Frequently Asked Questions

Does California follow the Uniform Premarital Agreement Act?

California has adopted the UPAA, so prenups must be in writing and signed voluntarily, with fair disclosure or a knowing waiver.

Do I need a lawyer for a prenup in California?

Independent counsel is strongly advised so both parties understand their rights, but in most states it is not strictly required for the agreement to be valid. A lawyer helps avoid the mistakes that get prenups thrown out.
