Frequently asked questions
When must a prenup be signed?
Before the marriage is registered at the district office. It is recorded with the marriage registration.

Can it be changed later?
Changes after marriage generally require court approval, so get it right before registration.

Recognition depends on the other country. Translation and legalisation may be needed.
