How have courts treated the issue of a spouse's right to make a gift of community property under section 5125(b) of the California Marriage Act?

Appellant attempts to equate the choosing of the method of payment of a pension with the making of a gift of community property in order to invoke the rule that "a gift made in violation of section 172 [now 5125(b) ] is, as against the donee, voidable by the wife in its entirety during the husband's lifetime [citations], and to the extent of one-half after his death [citations]." (Fields v. Michael (1949) 91 Cal.App.2d 443, 448, 205 P.2d 402.)
