Article 3. Spousal Support of California Family Law Code >> Division 9. >> Part 1. >> Chapter 3. >> Article 3.

The provisions of an agreement for support of either party shall be deemed to be separate and severable from the provisions of the agreement relating to property. An order for support of either party based on the agreement shall be law-imposed and shall be made under the power of the court to order spousal support.

(a) Except as provided in subdivisions (b) and (c), the provisions of an agreement for the support of either party are subject to subsequent modification or termination by court order.
  (b) An agreement may not be modified or terminated as to an amount that accrued before the date of the filing of the notice of motion or order to show cause to modify or terminate.
  (c) An agreement for spousal support may not be modified or revoked to the extent that a written agreement, or, if there is no written agreement, an oral agreement entered into in open court between the parties, specifically provides that the spousal support is not subject to modification or termination.

If an obligation under an agreement for settlement of property to a spouse or for support of a spouse is discharged in bankruptcy, the court may make all proper orders for the support of the spouse, as the court determines are just, having regard for the circumstances of the parties and the amount of the obligations under the agreement that are discharged.

Sections 3590 and 3591 are effective only with respect to a property settlement agreement entered into on or after January 1, 1970, and do not affect an agreement entered into before January 1, 1970, as to which Chapter 1308 of the Statutes of 1967 shall apply.
