In California, "domestic partnership agreement" can mean two different things. It can mean the state registration that makes two people registered domestic partners, with the same rights and duties as spouses. It can also mean a private written contract the partners sign to decide how their property, debts and support will be handled.
Most people facing this question are partway through something real. Some registered years ago, perhaps before they could marry, and now wonder what that filing actually committed them to. Some later married the same partner and are unsure whether the partnership still exists. Others are considering registration and want to know what a private agreement could protect. This article separates the two meanings, explains the rules that govern each, and shows how a partnership is registered, combined with marriage and ended.
What a Domestic Partnership Agreement Means Under California Law
Family Code section 297 defines the relationship itself: "Domestic partners are two adults who have chosen to share one another's lives in an intimate and committed relationship of mutual caring." A partnership is established when both people file a Declaration of Domestic Partnership with the Secretary of State and, at the time of filing, all of the statute's requirements are met:
- Neither person is married to someone else or in another domestic partnership that has not been terminated, dissolved or adjudged a nullity.
- The two are not related by blood in a way that would prevent them from marrying each other in California.
- Both are at least 18, except as section 297.1 provides.
- Both are capable of consenting to the domestic partnership.
That filing is the first meaning of "domestic partnership agreement." It is a public declaration on a state form, not a negotiated contract. The California Secretary of State publishes the standard Declaration of Domestic Partnership (Form DP-1) and also lists a confidential version (Form DP-1A). The Secretary of State's domestic partnership page is the authoritative source for the current forms, instructions and filing fees.
The second meaning is a private contract. Partners may write their own agreement about who owns what, how assets are managed, and what support, if any, one owes the other. People often use "domestic partnership agreement" loosely for this document. Couples who live together without registering sometimes sign a similar contract, usually called a cohabitation agreement. That kind of agreement is discussed in our article on cohabitation agreements for gay couples. It does not create domestic partner status, and the state registration does not by itself settle the private terms a couple may want.
Rights and Duties That Registration Creates
Family Code section 297.5(a) sets the core rule. Registered domestic partners "shall have the same rights, protections, and benefits, and shall be subject to the same responsibilities, obligations, and duties under law" as spouses, whatever the source of those rights: statutes, regulations, court rules, government policies or common law. Section 297.5(b) extends the same equivalence to former registered domestic partners.
That rule came from AB 205 (Stats. 2003, ch. 421). From January 1, 2005, registered domestic partners have the rights and duties of spouses, whenever they registered. A couple who filed in 2001 and a couple who filed in 2015 stand in the same position under California law today.
In practice, spousal equivalence reaches nearly every part of family law:
- Community property. Community property is the property that belongs equally to both spouses because it was acquired during the relationship. The same rules apply to registered partners.
- Support. The duty of support between registered partners mirrors the duty between spouses, during the partnership and, in the right circumstances, after it ends.
- Parentage. Because section 297.5 applies spousal rules to partners, the parentage presumptions that apply to a married couple's child generally apply to a registered partner's child too. For many families with a non-biological parent, this is the most important consequence of registration.
Section 297.5(k)(1) adds a timing rule that often matters most when couples later look back. For community property, shared debts, post-dissolution support and property rights between the partners, any legal reference to "the date of a marriage" is treated as the date the partnership was registered with the state. For couples whose lives together began well before any legal relationship, that registration date is often where the analysis of their property starts.
Federal treatment is a separate question. Section 297.5 governs California law. How a federal agency treats a registered domestic partnership falls outside California family law and is not covered here.
Registration also gives a couple the default rules, not tailored ones. Anything the partners want to arrange differently from those defaults has to come from a private written agreement.
What a Private Domestic Partnership Property Agreement Can Cover
Family Code section 1500 states the basic permission: "The property rights of spouses prescribed by statute may be altered by a premarital agreement or other marital property agreement." Through section 297.5, that permission extends to registered domestic partners.
The timing of the agreement matters, because different rules apply.
An agreement signed before registration is the closest parallel to a premarital agreement. That term has a precise definition in section 1610(a): "an agreement between prospective spouses made in contemplation of marriage and to be effective upon marriage." California's Uniform Premarital Agreement Act is written for that kind of agreement. Section 297.5(k)(2) also has a narrow rule for partners who registered before January 1, 2005: an agreement they made intending to be governed by sections 1600 to 1620 is enforceable under those sections if it complies with them, apart from its effective date, and was fully executed and in force as of June 30, 2005.
For premarital agreements, the statutes set out the scope and the limits:
- It must be in writing and signed by both parties (section 1611).
- It may cover property rights "whenever and wherever acquired," management and control of property, disposition of property on separation, dissolution or death, wills and trusts carrying out the agreement, life insurance death benefits, choice of law, and "any other matter... not in violation of public policy or a statute imposing a criminal penalty" (section 1612(a)).
- "The right of a child to support may not be adversely affected" (section 1612(b)).
- A spousal support provision is not enforceable if the party it is enforced against had no independent lawyer when signing, or if the provision is unconscionable at the time of enforcement (section 1612(c)).
- The agreement is not enforceable if it was not signed voluntarily. For later agreements, a court will treat it as involuntary unless it finds, among other things, that the challenging party had independent counsel or waived counsel in a separate writing after being advised at least seven calendar days before signing (section 1615).
An agreement signed after registration is a different instrument, comparable to a postnuptial agreement. The premarital agreement act does not govern it. Instead, Family Code section 721(b) applies. Spouses, and therefore registered partners, owe each other "a duty of the highest good faith and fair dealing," and "neither shall take any unfair advantage of the other." That duty includes giving true and full information about anything affecting community property. A post-registration agreement that favors one partner is examined against that fiduciary standard.
How these agreements are typically structured is covered in more depth in our pages on prenuptial agreements for LGBTQ+ couples and LGBT post-nuptial agreements.
Registration, the Confidential Declaration, and the Secretary of State Process
Family Code section 298.5(a) provides that two people who want to become domestic partners "may complete and file a Declaration of Domestic Partnership with the Secretary of State." The Secretary of State registers the declaration and returns a copy, a Certificate of Registered Domestic Partnership, and an informational brochure to the mailing address the partners supply. The certificate shows each partner's name before registration and any new name chosen at registration.
The standard filing is Form DP-1. The Secretary of State also lists a confidential declaration, Form DP-1A, for some couples. Who may use it, where it is filed, and how its records can be accessed are set by current Secretary of State rules. The Secretary of State's site is the place to confirm those details and current fees, since this article does not restate them.
The registration date carries legal weight. Under section 297.5(k)(1), as described above, it serves as the "date of marriage" for community property and related rights. Earnings and acquisitions before that date are analyzed differently from those after it. That is why couples with long histories before registration often find that the filing date shapes the property case more than the date they moved in together.
One document is often confused with registration. Some employers and benefit plans ask for their own domestic partner affidavit before covering a partner. That is a private employer form. It is not a state registration, and signing one does not create a California domestic partnership.
Domestic Partnership and Marriage: Two Separate Legal Relationships
Section 297(b)(1) makes exclusivity a condition of registering: neither person may be married to someone else or in another unterminated domestic partnership. Section 298.5(c) adds the reverse rule. A person who has filed a declaration may not file a new one or enter a civil marriage "with someone other than their registered domestic partner" until the most recent partnership has been terminated or dissolved, or declared a nullity by final judgment. The bar does not apply if the earlier partnership ended because a partner died.
Marrying the same partner is allowed, and it raises a frequent question. When registered partners marry each other, the partnership does not disappear into the marriage. Family Code section 299(e) provides that partners "who are also married to one another may petition the court to dissolve both their domestic partnership and their marriage in a single proceeding." The law treats them as two relationships that a court can end together. Our article on LGBTQ divorce and domestic partnerships discusses how that plays out when both exist.
History explains why so many couples have both. In November 2008, California voters approved Proposition 8, providing that only marriage between a man and a woman is valid or recognized in California. California allowed no new same-sex marriages from November 2008 until after Hollingsworth v. Perry was decided on June 26, 2013. That case decided standing only: the petitioners did not have standing to appeal the District Court's order, and the Ninth Circuit's judgment was vacated and remanded. During those years, registration was the available route for many couples to a spouse-like legal status in California, and many of those couples married each other later.
Dissolving a Domestic Partnership in California
Section 299 sets out two ways a registered partnership can end while both partners are living. Reading these rules can be hard when a relationship is already coming apart. Separating or moving out does not end the partnership by itself.
Summary termination through the Secretary of State. Under section 299(a), partners may end the partnership without a court case by filing a Notice of Termination of Domestic Partnership with the Secretary of State. The conditions at the time of filing include:
- Both partners sign the notice.
- There are no children of the relationship born before or after registration, or adopted by the partners after registration, and neither partner, to their knowledge, is pregnant.
- The partnership is not more than five years in duration.
- Neither partner has an interest in real property, except a qualifying residential lease with no purchase option that ends within one year of filing.
- Unpaid obligations incurred after registration, excluding car loans, stay within the limit set by reference to section 2400.
The statute lists further conditions, and current forms and instructions are on sos.ca.gov.
Dissolution in superior court. Partners who do not meet those conditions, or who disagree, file for dissolution in superior court. Because section 297.5 applies spousal rules, the case follows the same general framework as a divorce and uses Judicial Council family law forms. The California Courts self-help pages explain the process and forms.
Several divorce rules carry over:
- Waiting period. Under section 2339(a), a dissolution judgment is not final to end the relationship until six months after service of the summons and petition or the respondent's appearance, whichever comes first. Through section 297.5, that rule generally applies to partners as well, and section 2339(b) lets a court extend the period for good cause.
- Property. Community property built during the partnership is divided under the same rules as in a divorce, subject to any valid private agreement.
- Support. Section 4320 lists what a court considers when ordering support. The factors include each party's earning capacity, contributions to the other's education or career, ability to pay, needs based on the standard of living, assets and obligations, the duration of the relationship, age and health, and documented evidence of any history of domestic violence. That last factor is addressed further in our article on same-sex domestic violence.
If the partners also married each other, section 299(e) lets one court proceeding end both relationships.
When a Domestic Partnership Agreement Needs an Attorney
A private agreement signed without separate lawyers is easier to attack. For premarital agreements, sections 1612(c) and 1615 tie enforceability to independent counsel, voluntary signing and disclosure. For agreements signed after registration, section 721's fiduciary duty invites close review of any terms that favor one partner.
Dissolution calls for the same legal analysis as a divorce. A partnership does not simplify the property, support or custody questions. When a couple's history includes years together before registration, a registration and a later marriage, and property acquired across those periods, the analysis usually becomes more involved, not less.
Parentage deserves separate attention. Questions about a child conceived through assisted reproduction, a child born before the partners registered, or a non-biological parent's status are governed by California's version of the Uniform Parentage Act. Those rules are distinct, and the answer depends on facts such as timing, consent and the family's legal history.

If You'd Like to Talk Through Your Partnership and Its History
Domestic partnership questions rarely turn on the statute alone. They usually depend on dates: when the couple registered, whether and when they married, what was acquired before and after each, and whether any agreement was signed and how. A consultation goes through that timeline. It covers which relationships legally exist, which termination route may be available, how a private agreement is likely to be read, and, where children are involved, how each parent's legal status was established. For readers whose main question concerns an adoption itself, the firm does not handle adoption matters, though the related parentage, custody or dissolution questions are within its practice.
