Family Code Section 297 provides:
(a) Domestic partners are two adults who have chosen to share one another’s lives in an intimate and committed relationship of mutual caring.
(b) A domestic partnership shall be established in California when both persons file a Declaration of Domestic Partnership with the Secretary of State pursuant to this division, and, at the time of filing, all of the following requirements are met:
(1) Both persons have a common residence.
(2) Neither person is married to someone else or is a member of another domestic partnership with someone else that has not been terminated, dissolved, or adjudged a nullity.
(3) The two persons are not related by blood in a way that would prevent them from being married to each other in this state.
(4) Both persons are at least 18 years of age.
(5) Either of the following:
(A) Both persons are members of the same sex.
(B) One or both of the persons meet the eligibility criteria under Title II of the Social Security Act as defined in 42 U.S.C. Section 402(a) for old-age insurance benefits or Title XVI of the Social Security Act as defined in 42 U.S.C. Section 1381 for aged individuals. Notwithstanding any other provision of this section, persons of opposite sexes may not constitute a domestic partnership unless one or both of the persons are over the age of 62.
(6) Both persons are capable of consenting to the domestic partnership.
(c) “Have a common residence” means that both domestic partners share the same residence. It is not necessary that the legal right to possess the common residence be in both of their names. Two people have a common residence even if one or both have additional residences. Domestic partners do not cease to have a common residence if one leaves the common residence but intends to return.
