What Should I Do If the Reviewer Couldn’t Finalize the Review in the Journal’s Given Time?

By Dr. Aanya Mehta
Research Writer & Professional Business Communicator

If you are wondering, “What should I do if the reviewer couldn’t finalize the review in the journal’s given time?”, the most important answer is simple: the reviewer should contact the handling editor or journal office as soon as possible rather than remain silent, rush an inadequate report, or assume the deadline will automatically be extended. If only a short additional period is required, the reviewer can explain the situation briefly and request a realistic extension. If completing a useful review is no longer feasible, the more responsible option may be to withdraw from the assignment so the editor can approach another reviewer.

Missing a peer-review deadline is not automatically an ethical failure or a sign of unprofessional conduct. Researchers review manuscripts alongside teaching, clinical work, fieldwork, grant deadlines, administrative responsibilities, conferences, and their own research. Unexpected events can also interfere with a commitment that seemed manageable when the invitation was accepted. What matters is how the delay is handled.

Timeliness is nevertheless important because peer review affects authors, editors, and the journal’s publication workflow. Wiley’s publishing-ethics guidance states that reviewers should agree to review only within their expertise and within a reasonable timeframe, while editors should work toward timely peer review and avoid unnecessary delays. Elsevier similarly advises prospective reviewers to consider whether they genuinely have time to meet the deadline before accepting an invitation.

The appropriate response also depends on who you are. A reviewer who is running late should communicate with the editor. An editor may decide to extend the deadline, send a reminder, or seek another reviewer. An author who notices that peer review is taking longer than expected should normally contact the editorial office rather than attempting to identify or approach the reviewer directly.

This guide explains what to do before and after a missed reviewer deadline, how to request an extension professionally, when withdrawal may be preferable, what authors should do while waiting, and how to prevent the same problem in future assignments.

Quick Answer: What Should You Do If a Reviewer Cannot Finish on Time?

If you are the reviewer, contact the journal’s handling editor or editorial office immediately. State that you need additional time, give a realistic date by which you can submit the report, and ask whether an extension would still be useful to the editor.

If you can finish a careful review within a short extension, requesting more time is usually more constructive than submitting a rushed report. However, if your circumstances mean you cannot provide a meaningful review within a reasonable additional period, inform the editor promptly and offer to withdraw.

Do not assume that an automated reminder means the editor has already granted additional time. Journal workflows differ, and deadlines can be handled differently across publishers, journals, disciplines, and editorial systems.

If you are the author, you generally do not need to take action simply because a reviewer is late. The editor manages the reviewers. If the overall review period becomes substantially longer than the journal’s stated or typical timeline, a polite status inquiry to the editorial office is appropriate.

Key Takeaways

• Contact the editor early if you know you cannot meet the review deadline.
• Ask for an extension only if you can provide a specific, realistic revised completion date.
• If you can no longer complete a useful review, withdrawing promptly may be better than creating an indefinite delay.
• Do not sacrifice review quality merely to meet a deadline.
• Do not delegate the manuscript or share confidential material with another researcher without the journal’s permission.
• Authors should communicate with the editorial office, not the reviewer, about unusually long delays.
• Journal procedures vary, so always follow the instructions in the review invitation and the journal’s reviewer guidelines.

Methodology and Academic Sources

The guidance in this article is based on established peer-review principles and current information from major scholarly publishers and publishing-ethics resources.

Publisher-specific procedures differ. Wiley notes that peer-review timelines vary by journal and that reviewers should follow the timing given in their invitation. Elsevier advises reviewers to consider expertise, conflicts of interest, and available time before accepting an invitation. Springer Nature similarly emphasizes considering whether the reviewer can meet the requested deadline before accepting a review assignment.

Therefore, the practical guidance below should not be interpreted as a universal journal rule. Always check the specific review invitation, journal instructions, editorial platform, and correspondence from the handling editor.

Why Reviewer Deadlines Matter

A reviewer deadline is intended to keep editorial decision-making moving while still allowing enough time for a careful scholarly evaluation.

A delayed review can affect several people. The author may be waiting for a decision before revising the study, completing a thesis requirement, applying for funding, presenting findings, or progressing another related manuscript. The editor may also be waiting for enough independent reports to make an informed decision.

At the same time, speed should not replace quality. A superficial report submitted solely to avoid being late may be less useful than a brief, transparent request for additional time.

Elsevier advises researchers to consider whether they have enough time before accepting a review invitation and to respond to invitations promptly because delays can slow the review process for authors. Wiley’s ethics guidance likewise identifies timeliness as part of an efficient peer-review process.

The practical objective is therefore not simply “submit something before the clock expires.” It is to provide a useful review within an agreed timeframe—or tell the editor promptly when that is no longer possible.

What Should I Do If the Reviewer Couldn’t Finalize the Review in the Journal’s Given Time?

1. Contact the Editor Before the Deadline If Possible

If you realize several days before the deadline that you will not finish, write to the editor immediately.

You do not need to provide a lengthy personal explanation. A concise message can state:

• that you are still willing to complete the review;
• that you will be unable to meet the original deadline;
• how much additional time you require;
• the specific date by which you expect to submit;
• whether the extension would still be useful to the editor.

Early communication gives the editor options. The editor may approve the extension, request a faster turnaround, invite another reviewer, or decide that your report is no longer required.

2. Estimate the Extra Time Realistically

Avoid asking for “a few more days” unless you have actually checked your schedule.

Consider what remains:

• Have you read the full manuscript?
• Have you examined the methods carefully?
• Do figures, tables, appendices, or supplementary materials still require review?
• Do you need to verify important references or methodological issues?
• Have you drafted your major and minor comments?
• How much uninterrupted time can you realistically allocate?

A realistic request is better than requesting three additional days and then missing the revised deadline too.

3. Do Not Rush a Poor-Quality Review

A deadline does not justify replacing careful evaluation with a few hurried sentences.

The reviewer has been invited because the editor requires informed scholarly judgment. If completing that judgment properly requires a modest extension, ask for one.

Elsevier’s guidance emphasizes that peer review requires the reviewer to assess the manuscript carefully and provide useful feedback, while the ultimate editorial decision remains with the editor.

Quality and timeliness should therefore be balanced rather than treated as opposing absolutes.

4. Withdraw If You Can No Longer Complete the Review

Sometimes an extension will not solve the problem.

You may need to withdraw because of:

• unexpected illness or personal circumstances;
• an urgent professional commitment;
• prolonged travel;
• a workload change;
• discovery that the manuscript requires expertise you do not sufficiently possess;
• a conflict of interest noticed after accepting;
• realization that you cannot finish within any reasonably useful timeframe.

In those circumstances, tell the editor promptly.

Withdrawing professionally is generally preferable to repeatedly requesting extensions without a realistic prospect of completing the review.

What If the Reviewer Deadline Has Already Passed?

If the deadline has already passed, contact the editor now rather than waiting for another reminder.

A useful message should acknowledge the missed deadline without excessive explanation and clearly state one of two things:

1. you can still complete the review by a specific near-term date and would like confirmation that the editor still wants it; or
2. you cannot complete the review promptly and wish to withdraw so the editor can proceed.

Some editorial platforms have mechanisms for managing overdue reviewers. Elsevier’s Digital Commons documentation, for example, describes editor options that can include reminders, revision of a reviewer’s due date, selecting another reviewer, or giving up on an overdue reviewer.

That does not mean every journal follows the same process. It shows why communicating with the editor is important: the editor may have several workflow options available.

Can You Still Submit After the Deadline?

Possibly, but do not assume so.

A journal’s submission system may continue to permit an overdue report, the editor may extend the deadline, or the editor may already have replaced the reviewer. Editorial systems and journal policies differ.

If your review is ready but the system no longer allows submission, contact the journal office rather than sending confidential material through an unapproved channel.

Extension or Withdrawal: How Should You Decide?

The following table offers a practical decision framework.

Situation	Usually Sensible Action	Why
You need only a few extra days and can commit to a date	Request an extension	Your report may still be useful without substantially disrupting the process
Most of the review is complete but unexpected work interrupted you	Ask the editor whether a short extension is acceptable	The editor can decide whether waiting is worthwhile
You have barely started and will remain unavailable for weeks	Consider withdrawing	The editor may be better served by finding another reviewer
You discover a conflict of interest	Inform the editor immediately	Objectivity and disclosure matter more than finishing the assignment
You realize the paper is substantially outside your expertise	Tell the editor and discuss withdrawal	Reviewing beyond your competence may produce unreliable evaluation
The deadline has passed but your report is almost finished	Contact the editor and give a precise submission date	The editor may still want the report
You already missed one extended deadline	Reassess honestly before requesting another extension	Repeated uncertain extensions may cause unnecessary delay

The central question is: Can you still provide a rigorous review soon enough to remain useful to the editor?

If yes, request an extension. If no, withdrawing promptly is often the more responsible choice.

How to Request a Peer-Review Deadline Extension Professionally

A reviewer-extension request does not need to be elaborate.

A suitable message might say:

Dear Dr. [Editor Name],
Thank you again for the opportunity to review manuscript [reference number/title]. I am still working on the review, but unfortunately I will not be able to submit a sufficiently careful report by the current deadline. If it would still be useful to you, could the deadline please be extended to [date]? I expect to complete the review by then. If that timing would cause difficulty for the editorial process, please let me know and I will understand if you prefer to reassign the review.
Kind regards,
[Name]

This wording works because it:

• takes responsibility;
• keeps the explanation brief;
• gives a definite date;
• emphasizes review quality;
• lets the editor decide whether the extension is useful.

What Not to Write

Avoid vague messages such as:

“I’m busy. I will submit when possible.”

The editor cannot plan around an undefined timeline.

Also avoid repeatedly promising “tomorrow” unless you are genuinely certain the review will be ready.

What Editors Can Do When a Reviewer Is Late

A late review does not leave an editor with only one option.

Depending on the journal and editorial system, an editor may:

• send a reminder;
• extend or revise the review deadline;
• invite another reviewer;
• continue waiting if the report is expected shortly;
• decide that sufficient reviews have already been received;
• end the outstanding review assignment.

Elsevier’s editorial-system documentation explicitly describes options including reminding a delinquent reviewer, revising the report due date, finding another reviewer, and ceasing to wait for a reviewer.

Springer Nature’s reviewer-management information likewise describes configurable review timelines and automated reminders within its systems.

The editor—not the reviewer or author—decides how the delayed report fits into the manuscript’s editorial process.

What Should an Author Do If a Reviewer Is Taking Too Long?

If you are the manuscript author rather than the reviewer, the recommended approach is different.

First, Avoid Assuming Something Has Gone Wrong

Peer review rarely proceeds with perfect predictability.

An editor may need time to:

• identify appropriate reviewers;
• obtain enough accepted invitations;
• wait for reports;
• replace reviewers who decline;
• obtain specialist methodological input;
• assess conflicting reviewer recommendations.

A status that remains unchanged for some time does not necessarily indicate neglect.

Check the Journal’s Published Timeline

Some journals provide typical or median review information. Treat such figures as guidance rather than guaranteed decision dates.

Wiley notes that peer-review duration varies by journal and recommends consulting the journal’s information for its particular process.

Contact the Editorial Office Politely When Appropriate

If the review has clearly exceeded the journal’s indicated timeframe or has remained unchanged for an unusually long period, a short inquiry is reasonable.

For example:

Dear Editorial Office,
I am writing to ask whether there is any update regarding manuscript [reference number], submitted on [date]. I understand that peer review timelines can vary, and I appreciate the time contributed by the editor and reviewers. I would be grateful for any information you can provide about the current status.
Kind regards,
[Author Name]

Avoid demanding an immediate decision or sending repeated inquiries within very short intervals.

Do Not Contact the Reviewer Directly

Peer-review identities may be confidential, and correspondence between authors and reviewers is normally managed through the journal.

Wiley’s publishing-ethics guidance states that editors should mediate exchanges between authors and reviewers during peer review and emphasizes maintaining confidentiality.

If you happen to suspect who a reviewer is, do not approach that person about your manuscript.

Confidentiality, Delegation, and AI Tools When a Deadline Is Tight

A missed deadline does not remove the reviewer’s confidentiality obligations.

Do Not Give the Manuscript to Someone Else to Finish

A reviewer may be tempted to ask a colleague, postdoctoral researcher, or student to help complete the report.

Do not do this without the journal’s permission.

The reviewer invitation was issued to a specific person, and the manuscript is confidential. Wiley’s guidance states that reviewers should inform editors if peer-review work is delegated and emphasizes the confidentiality of manuscripts under review.

If you believe involving a qualified co-reviewer would improve the process, ask the editor first.

Be Extremely Careful With Generative AI

Do not upload a confidential manuscript into a public generative-AI system simply because you are short of time.

Elsevier states that reviewing involves responsibilities attributable to humans and warns reviewers not to share confidential review materials without authorization. Wiley’s current publishing-ethics guidance states that peer reviewers should not upload manuscripts or manuscript components to AI technology because doing so may compromise confidentiality, privacy, or copyright; it also emphasizes that responsibility for a peer-review report remains with the human reviewer.

Always follow the specific journal’s current AI and confidentiality policy.

Common Mistakes When a Reviewer Cannot Finish on Time

Mistake 1: Saying Nothing

Silence leaves the editor unable to determine whether your report is coming.

Better approach: Send a concise update as soon as you identify the delay.

Mistake 2: Waiting Until Long After the Deadline

The earlier the editor knows, the more options are available.

Better approach: Communicate before the deadline whenever possible.

Mistake 3: Requesting an Unrealistic Extension

An extension does not help if the replacement deadline will also be missed.

Better approach: Review your schedule first and offer a date you can genuinely meet.

Mistake 4: Rushing the Review

A rushed report may miss methodological problems, misunderstand the argument, or offer unhelpful comments.

Better approach: Ask for a modest extension if careful review is still feasible.

Mistake 5: Delegating Without Permission

Confidentiality continues even when you are under time pressure.

Better approach: Ask the editor before involving another person.

Mistake 6: Asking for Multiple Extensions Without Reassessing

Repeated extensions can turn a temporary delay into a prolonged bottleneck.

Better approach: If your availability has fundamentally changed, consider withdrawing.

Mistake 7: Authors Trying to Identify the Late Reviewer

The author should not manage the reviewer relationship.

Better approach: Contact the editorial office.

Mistake 8: Assuming Automated Reminders Equal an Extension

A reminder means the review is outstanding; it does not necessarily establish a new agreed deadline.

Better approach: Confirm the revised timing with the journal when necessary.

Practical Example 1: A Reviewer Needs Five More Days

Situation

A researcher accepts a manuscript review with a three-week deadline. Two weeks later, an unexpected grant deadline consumes several working days. The reviewer has read the manuscript carefully but has not completed the written report.

Poor Response

The reviewer says nothing and submits ten days late.

Better Academic Approach

The reviewer contacts the editor four days before the deadline and says the review can be completed five days later.

Why This Is Stronger

The editor now has enough information to decide whether waiting for the report is reasonable.

A limited, realistic extension protects review quality without creating unnecessary uncertainty.

Practical Example 2: A Reviewer Cannot Complete the Assignment for Several Weeks

Situation

A reviewer accepts an invitation but then faces an unforeseen professional or personal commitment. Only the abstract and part of the manuscript have been read, and the reviewer will not have sufficient time for approximately a month.

Poor Response

The reviewer repeatedly asks for one-week extensions in the hope that the workload will improve.

Better Academic Approach

The reviewer informs the editor that completing the review promptly is no longer feasible and offers to withdraw.

Why This Is Stronger

Withdrawing may initially feel inconvenient, but it allows the editor to invite another qualified reviewer instead of waiting through several uncertain extensions.

Practical Example 3: The Deadline Has Passed and the Report Is Nearly Finished

Situation

The report was due yesterday. The reviewer has completed the substantive assessment and needs one additional day to organize the comments clearly.

Better Academic Approach

The reviewer immediately contacts the editor:

“I apologize for missing yesterday’s deadline. My assessment is substantially complete and I can submit the finalized report by tomorrow evening. Please let me know if the review is still required.”

Why This Is Stronger

The editor receives a precise timeline and can decide whether the near-complete report is worth waiting for.

Practical Example 4: An Author Has Been Waiting Longer Than Expected

Situation

An author submitted a research paper several months ago. The tracking system indicates that peer review is still underway, and the journal’s published information suggests decisions are often made sooner.

Poor Response

The author tries to determine who the reviewers are and sends messages to researchers suspected of reviewing the paper.

Better Academic Approach

The author sends one courteous inquiry to the editorial office asking whether an update is available.

Why This Is Stronger

It respects peer-review confidentiality and keeps communication within the journal’s established editorial process.

Reviewer Deadline Checklist

Before deciding what to do, ask yourself:

• Do I still have the expertise required to evaluate this manuscript properly?
• Have I identified any conflict of interest that should be disclosed?
• How much of the manuscript have I genuinely reviewed?
• How many additional hours of focused work are required?
• Can I provide a specific revised completion date?
• Is the additional time likely to be short enough to remain useful to the editor?
• Have I contacted the editor before the original deadline where possible?
• Am I maintaining the confidentiality of the manuscript and review process?
• Have I avoided involving another person without editorial permission?
• If I cannot finish within a reasonable period, would withdrawing be more responsible?

If several answers raise doubts about whether you can complete the review soon, inform the editor rather than continuing indefinitely.

How to Prevent Reviewer Deadline Problems in Future

The easiest deadline problem to manage is the one you avoid before accepting the invitation.

Elsevier recommends considering your expertise, conflicts of interest, and available time before agreeing to review. Springer Nature provides similar advice, including checking whether you can meet the review deadline before accepting.

1. Read the Invitation Carefully

Check:

• the due date;
• manuscript topic;
• article type;
• expected review format;
• approximate manuscript length;
• supplementary materials;
• conflicts-of-interest requirements;
• journal-specific reviewer policies.

2. Check Your Calendar Before Accepting

Consider known commitments during the entire review period, not just the current week.

3. Conduct an Early First Read

Do not wait until the final two days to discover that the paper is much more complex than expected.

An early scan can reveal:

• whether the paper is actually within your expertise;
• whether specialist methodological analysis is required;
• whether supplementary files substantially increase the workload;
• whether a conflict becomes apparent.

4. Reserve Specific Review Sessions

A manuscript review competes with other tasks unless time is deliberately allocated.

Consider reserving separate periods for:

1. initial reading;
2. detailed methodological and substantive evaluation;
3. verification of major concerns;
4. writing and revising the report.

5. Decline When Your Schedule Is Already Full

Declining an invitation promptly is preferable to accepting automatically and later discovering that there is no realistic time to complete it.

Elsevier encourages reviewers who decline to respond quickly and, where appropriate, suggest suitable alternative reviewers.

How Contentxprtz May Help Authors After Peer Review

A delayed reviewer report itself is an editorial workflow matter; an academic editing service cannot legitimately accelerate a journal’s independent peer-review decision or guarantee when a reviewer will respond.

Professional academic support becomes more relevant after reviewer comments arrive, particularly when an author needs help improving clarity, organizing revisions, checking whether each reviewer comment has been addressed, refining the language of a revised manuscript, or preparing a professional point-by-point response.

The Contentxprtz service brief identifies academic editing, research-paper editing, journal manuscript support, publication assistance, and reviewer-response support among its relevant academic communication services.

Researchers who have received reviewer comments and want an independent language, clarity, or structural review can explore the Contentxprtz Research Paper Editing Service.

Such assistance should support the researcher’s own intellectual work rather than replace responsibility for the study, data, interpretation, claims, citations, or final submission.

Summary: What to Do When a Reviewer Cannot Finish the Review on Time

If a reviewer cannot meet a journal’s deadline, the best response is usually prompt, transparent communication with the editor.

A reviewer who needs only a limited amount of additional time should request an extension and provide a realistic completion date. A reviewer who can no longer provide a timely, rigorous assessment should tell the editor and consider withdrawing.

Do not rush a poor-quality review, disappear without explanation, delegate a confidential manuscript without permission, or upload review materials into tools that conflict with the journal’s confidentiality or AI policies.

Editors may have several options for managing an overdue review, including reminders, revised deadlines, or replacement reviewers. Authors, meanwhile, should generally allow the editorial team to manage reviewers and contact the editorial office politely if the overall process becomes unusually long.

The key principle is simple: a manageable delay can often be resolved; an unexplained delay is much harder for an editor to manage.

Frequently Asked Questions

1. What should I do if the reviewer couldn’t finalize the review in the journal’s given time?

If you are the reviewer, contact the handling editor or editorial office immediately. Explain briefly that you cannot meet the original deadline and either request a realistic extension or withdraw if completing the review soon is no longer possible.

Do not wait silently for repeated reminders. The editor needs to know whether your report is still expected so that the manuscript can be managed appropriately.

If you are the author, the situation is different. You normally do not need to intervene when an individual reviewer is late because the editor manages reviewer deadlines. If the complete peer-review process becomes substantially longer than the journal’s indicated timeframe, send a polite inquiry to the editorial office.

2. Is it acceptable for a peer reviewer to ask for an extension?

Yes, an extension request can be reasonable when unexpected circumstances arise and the reviewer can still provide a careful report within a realistic additional period.

The reviewer should request the extension as early as possible and state a specific proposed completion date.

Whether the extension is granted is up to the journal or editor. Different journals have different workflows, so reviewers should not assume an extension is automatic.

If the reviewer needs a very long or uncertain delay, withdrawal may be more helpful than repeatedly extending the assignment.

3. How long an extension should a reviewer request?

There is no universal extension period that applies to all journals or disciplines.

Request only the amount of additional time you genuinely need. Before writing to the editor, estimate the remaining reading, analysis, checking, and report-writing work and compare it with your actual availability.

A precise request such as “Could I submit by 18 August?” is more useful than “I need more time.”

Remember that the editor may have manuscript-specific reasons for needing the report sooner and may choose to replace the reviewer rather than approve the extension.

4. What happens when a reviewer misses the deadline?

The outcome depends on the journal and its editorial system.

The reviewer may receive an automated or manual reminder. The editor may extend the deadline, contact the reviewer directly, invite an additional reviewer, or stop waiting for the overdue report.

Elsevier’s editorial workflow documentation, for example, describes options for reminding late reviewers, revising due dates, finding other reviewers, and ending an overdue review assignment.

Because procedures vary, a reviewer who has missed the deadline should contact the editorial office rather than guessing whether the review is still wanted.

5. Should I submit a rushed review rather than ask for more time?

Usually not if rushing would materially reduce the quality of your assessment.

A peer-review report should give the editor a reasoned evaluation and provide authors with useful scholarly feedback where appropriate. Submitting a superficial report merely to meet a deadline may fail to serve that purpose.

If a modest extension would allow you to complete the review properly, contact the editor. If you cannot complete a meaningful assessment within a useful timeframe, withdrawal may be preferable.

The objective is timely and responsible review, not deadline compliance at any cost.

6. Can I withdraw after I have already accepted a review invitation?

Yes, circumstances can change after acceptance, although you should notify the editor as soon as possible.

Withdrawal may be appropriate if you experience unexpected unavailability, discover a conflict of interest, realize the manuscript falls outside your expertise, or can no longer provide a useful review within a reasonable timeframe.

Do not simply stop responding. Explain briefly that you can no longer complete the review and allow the editor to make alternative arrangements.

If you know a qualified alternative reviewer, you may offer a suggestion when the journal permits it, but the editor decides whom to invite.

7. Can I ask a student or colleague to help me finish an overdue review?

Not without permission from the journal or editor.

Peer-review manuscripts are confidential, and the invitation was issued to you. Sharing the manuscript with another person may violate journal policy if the editor has not authorized that person’s involvement.

Wiley’s ethics guidance emphasizes confidentiality and states that reviewers should inform editors when peer-review work is delegated.

If supervised co-review would be educational or useful, contact the editor first and follow the journal’s procedure.

8. Should authors contact the journal when a reviewer is late?

Authors can contact the editorial office when the overall review process has become unusually long, but they should usually avoid reacting to every short delay.

Review timelines vary substantially among journals and individual manuscripts. A reviewer may need replacement, an editor may be awaiting another report, or the paper may require specialist assessment.

When you do inquire, keep the message short, polite, and focused on manuscript status. Do not accuse reviewers or editors of negligence, and do not attempt to contact reviewers personally.

9. Can a late reviewer still submit the review after the deadline?

Sometimes, but it depends on the journal’s workflow and whether the editor still requires the report.

Some editorial systems retain options for managing reviewers whose assignments have become late, including changing due dates. However, the editor may already have obtained another review or decided to stop waiting.

If your report is nearly complete after the deadline, contact the editor immediately and provide an exact proposed submission time. If the system has closed the assignment, ask the editorial office what procedure to follow rather than sending manuscript-related material through an unofficial channel.

10. How can reviewers avoid missing future journal deadlines?

Before accepting an invitation, check three things carefully: expertise, conflicts of interest, and time.

Read the abstract and reviewer instructions, examine your calendar, and consider the manuscript’s likely complexity. Elsevier specifically recommends checking whether you have sufficient time before accepting, while Springer Nature likewise advises reviewers to assess whether they can meet the requested deadline.

After accepting, schedule the first reading early rather than waiting until the final days. If circumstances later change, contact the editor immediately.

A prompt decline at the invitation stage is usually easier for an editor to manage than a late withdrawal after several weeks.

Conclusion

When a reviewer cannot finalize a peer review within the journal’s requested time, the situation is usually best managed through early and specific communication.

If you remain capable of providing a rigorous review within a short additional period, request an extension and state exactly when you can submit. If your availability has changed substantially, withdrawing may allow the editor to move the manuscript forward more efficiently.

What should be avoided is equally important: do not disappear after accepting the assignment, repeatedly make unrealistic promises, rush an inadequate report, share the confidential manuscript without authorization, or assume that an automated reminder automatically changes your deadline.

For authors, reviewer delays can be frustrating, but reviewers are managed by the editor. Allow the editorial process to operate, check the journal’s stated expectations where available, and send a courteous status inquiry if the overall delay becomes substantial.

Once reviewer comments arrive, careful revision becomes the author’s responsibility. Self-review may be sufficient when the comments are straightforward and the manuscript is already clearly written. When comments are complex, the manuscript requires extensive language revision, or the response letter needs clearer organization, ethical professional editing can help strengthen communication while preserving the researcher’s original ideas and responsibility for the work.

Researchers seeking that kind of support can consider the Contentxprtz Research Paper Editing Service.
