Prenuptial agreement: what it can govern and where the limits are

A prenuptial agreement is not romantic, but it is often sensible, especially with a business, a large disparity in wealth, or a second marriage. It creates clarity for the case of divorce. But it has limits on form and content that you should know.

Your chances of getting your money back

In the prenuptial agreement you can govern the property regime (for example separation of property or a modified community of accrued gains), post-marital support and pension equalization. A prenuptial agreement must be notarized.
There are limits: a one-sided, grossly unfair disadvantage can be immoral and therefore invalid (§ 138 BGB; validity and exercise review by the courts). Child support cannot be waived to the detriment of the child.

Frequently asked questions

What can a prenuptial agreement govern?

Above all the property regime (such as separation of property or a modified community of accrued gains), post-marital support and pension equalization. It must be notarized. Child support is excluded from this; it cannot be excluded to the detriment of the child.

Can a prenuptial agreement be invalid?

Yes. If the agreement disadvantages one partner one-sidedly and grossly unfairly, it can be wholly or partly immoral and therefore invalid (§ 138 BGB). The courts examine this through a validity review and an exercise review. A balanced arrangement with advice on both sides is considerably more robust.
