......Agreements Enforced
.........Spousal Support Waivers
3 Cards On This Topic:

Spousal support waivers and limitations contained in written premarital agreements are not contrary to public policy and are not per se unenforceable.

The validity of a spousal support waiver depends on when it was executed; waivers executed after the enactment of the UPAA are presumptively valid (or at least not per se invalid).

Fam. Code §1612 (c) is not retroactive to PMA s/s waivers entered into before 1/1/2002.
