The guaranteed insurability option (Nachversicherungsgarantie) is a contract clause that appears mainly in occupational disability insurance policies. It allows you to increase your cover when certain life events occur, without undergoing a full health check again. This entry explains how the guarantee works, what limits it has and why the rules differ from tariff to tariff.
Short answer: The guaranteed insurability option is a contractual rule, not a statutory benefit. It allows increases on defined occasions, such as marriage, the birth of a child or a professional fresh start. Which occasions apply, which deadlines run and how large an increase may be are set by each tariff itself. Last updated: October 2026.
The key points in brief
- The guaranteed insurability option is a contract clause, not a statutory obligation.
- It allows increases on specified life events.
- If the conditions are met, the increase is made without a new health check.
- Occasions, deadlines and maximum amounts differ from tariff to tariff.
- After a deadline has passed, the right may lapse. That is why timing matters.
What does the term mean?
When you take out an occupational disability insurance, you generally have to answer health questions. If you need more cover later, you would normally have to submit a new application, in which pre-existing conditions can become a problem. The guaranteed insurability option is meant to make this step easier. It is not a blank cheque, however: the occasion must be named in the contract, and every increase has its price in the premium.

Typical occasions and what to check
Many tariffs name similar occasions. The list is a guide only. Your contract alone is binding.
| Occasion | What to check in the contract |
|---|---|
| Marriage or registered civil partnership | Whether the occasion is listed and which deadline runs from the event |
| Birth or adoption of a child | Whether the increase is possible in full or only up to a limit |
| Career start or salary increase | Which proof the insurer requires |
| Completion of an apprenticeship or degree | Whether the completion counts as an occasion and whether it must be documented |
The entries in the table are typical points to check and say nothing about any particular provider.
What to look for when you sign
- Read the clause in full and note every occasion it names.
- Check the deadline that runs from the event. Some tariffs require the increase within a few months.
- Clarify whether the increase is capped at a maximum sum or limited to a certain age.
- Compare how the guarantee interacts with any later dynamic increase, and note the effect on your premium.
Frequently asked questions
Do I need the guaranteed insurability option if I already have occupational disability insurance?
It is most useful if you can foresee needing more cover, for example when starting a family or after a significant jump in income. Whether the additional cost is worth it depends on your circumstances and should be checked individually.
Does the guarantee apply automatically?
No. It must be agreed in the contract. Whether it exists and in what form is set out in your contract documents and the policy conditions of the tariff.
What happens if I miss the deadline?
A later application may then be treated as a new application, which again requires a health check. It is therefore worth keeping occasions and deadlines in view early on.
Where can I find binding rules for my tariff?
In the policy conditions of your contract. If you are unsure, a personal review helps. You can find a reference to this kind of advice at Academycon (in German).
