The Shame Behind the Draft Email

You have drafted the email seven times. You cannot get past "I am writing to request...".Asking for an extension feels like admitting failure, especially when classmates are visibly submitting on time. It is not failure. Recurring threads on studis-online ("Verlangerung Bachelorarbeit"), gutefrage.net (Atteste-fur-Verlangerung), and Quora ("How do I ask for an extension") confirm what most graduates discover only later: extension requests are routine, frequently granted, and not recorded on the diploma. The shame is the only thing that needs to die first.

What Counts as a Valid Reason

ReasonRequired evidenceRealistic extension length
Medical (illness, mental health)Krankschreibung from GP / Hausarzt1 to 12 weeks
BereavementDeath certificate or short personal statement2 to 6 weeks
Severe family illnessBrief letter; sometimes medical confirmation2 to 8 weeks
Supervisor delayEmail trail showing the silenceEqual to the supervisor delay
No specific cause / scope underestimateNone — supervisor discretion1 to 4 weeks

Three Email Templates That Work

Template 1: Routine medical extension

Dear Professor [Last Name],

I am writing to request an extension of my thesis submission deadline from [current date] to [proposed date]. I have been unfit for work since [start date] (Krankschreibung attached). My current draft stands at approximately [%], and the proposed deadline allows me to complete the remaining work to the standard expected. Please let me know if you require additional documentation.

Best regards,
[Your name]

Template 2: Hartefall-grade extension (bereavement / severe illness)

Dear Professor [Last Name],

I am writing to request an extension under the Hartefall provision of [Prufungsordnung section / mitigating-circumstances policy]. [One sentence about the event without graphic detail]. The impact on my ability to work between [date] and [date] has been substantial. I would like to request submission by [date]. I have informed the Prufungsausschuss / DGS in parallel. Please let me know whether you would like to discuss this in person.

Best regards,
[Your name]

Template 3: Short extension without medical reason (2 weeks)

Dear Professor [Last Name],

I would like to request a 2-week extension of my thesis submission deadline, from [current date] to [new date]. The remaining work is concentrated in the discussion chapter and final formatting; the additional time will allow me to deliver a stronger final version rather than a hurried one. If this is not possible, I will submit on the original deadline. Thank you for considering.

Best regards,
[Your name]

What NOT to Over-Share

Focus on impact, dates, and evidence. Do not provide a detailed medical narrative. The institution needs the minimum information required to grant the request — not your symptoms, not your diagnosis, not your therapy notes. A Krankschreibung saying "unfit for work for 14 days" is sufficient. The same applies to mental-health reasons: see our companion piece on how to phrase a Krankschreibung request.

Why ~30% of Students Take an Extension

Survey data from German university administrations and UK Higher Education Statistics Agency reports converge on roughly 25 to 35 percent of thesis-stage students requesting some form of extension or mitigating-circumstances accommodation. You are not the exception; you are part of the median. The extension does not appear on your degree certificate, your supervisor has seen many of these, and the administrative process is routine.

The extension is not on your transcript. The unfinished thesis is.

After the Extension Is Granted

The next 4 weeks are critical. The extension only matters if the new deadline becomes real. If your draft is stalled, our structured reference draft is what makes the new deadline real — a document to react to, refine, and submit instead of one to start from blank.

Frequently Asked Questions

What counts as a valid reason for a thesis extension?

In Germany: a Krankschreibung (medical), a Hartefall (bereavement, severe family illness, accident), Mutterschutz/parental leave, or a demonstrably unforeseeable external event. In the UK and US: mitigating circumstances forms cover similar grounds, often including documented learning differences and equipment failures.

Will a thesis extension show on my degree certificate?

No. The degree certificate (Zeugnis) shows the awarded degree and final grades. The extension appears only as a slightly later submission date in the Prufungsamt internal record, which is not part of the diploma.

How much detail about my health do I have to provide?

The minimum the institution needs to grant the request — typically a Krankschreibung from your GP stating you are unfit to work for X days. You do not need to disclose the diagnosis. Focus on impact and dates, not narrative.

Can I ask for an extension without a medical reason?

Often yes, especially for short extensions of 1 to 4 weeks. Supervisors have discretion. The request is more likely to succeed if it is specific, brief, and offers a concrete revised deadline.

How early should I request an extension?

As soon as you know you will need it. Late requests submitted close to the deadline are harder to grant administratively and look less credible. Two to four weeks before the deadline is ideal.
