How is common law marriage defined in california?

In Australia the term de facto marriage is often used to refer to relationships between men and women who are not married but are effectively living as husband and wife for a period of time, however common-law marriage is sometimes heard. The Federal parliament has power to legislate for marriages, which it first did in 1959 with the Matrimonial Causes Act (covering divorces, etc.) and in 1961 with the Marriage Act, both of which are now replaced by the 1975 Family Law Act. The Federal parliament has no power over de-facto marriages, and thus all Australian states and territories have legislation covering aspects of de-facto marriages, such as property distribution, custody of children, etc. if a relationship ends. Most laws dealing with taxation, social welfare, pensions, etc. treat de-facto marriages in the same manner as solemnized marriages.
