California Code, Family Code - FAM § 4330

(a) In a judgment of dissolution of marriage or legal separation of the parties, the court may order a party to pay for the support of the other party an amount, for a period of time, that the court determines is just and reasonable, based on the standard of living established during the marriage, taking into consideration the circumstances as provided in Chapter 2 (commencing with Section 4320).

(b) When making an order for spousal support, the court may advise the recipient of support that the recipient should make reasonable efforts to assist in providing for their support needs, taking into account the particular circumstances considered by the court pursuant to Section 4320, unless, in the case of a marriage of long duration as provided for in Section 4336, the court decides this warning is inadvisable.
