What California Domestic Partnership Is and How It Works

A California domestic partnership is a legal relationship between two people who register with the state. Unlike marriage, which is a civil contract recognized across all 50 states and most countries, domestic partnership is a California-specific legal status. As of January 1, 2020, California stopped allowing new domestic partnerships for same-sex couples, but same-sex couples can still marry. However, opposite-sex couples where at least one partner is 62 or older may still form domestic partnerships.

The domestic partnership registry maintained by the California Secretary of State creates a legal record of the relationship. Once registered, domestic partners gain many of the same legal rights and responsibilities as married couples under California law. This includes hospital visitation rights, inheritance rights, health insurance benefits through employers, and tax filing status recognition by the state (though not the federal government for tax purposes).

Domestic partnerships were first introduced in California in 1999 as Assembly Bill 25. At that time, same-sex couples could not marry, so domestic partnership provided a legal structure for recognizing these relationships. Over the years, California expanded domestic partnership rights to nearly match those of marriage. When the U.S. Supreme Court legalized same-sex marriage nationwide in 2015, many same-sex domestic partners chose to convert their relationships to marriages.

The key distinction between domestic partnership and marriage in California today is that domestic partnership remains a state-level status. Federal benefits tied to marriage—such as Social Security spousal benefits, federal tax filing status, and immigration sponsorship—are not available through domestic partnership. For opposite-sex couples over 62, domestic partnership may serve as an alternative to marriage for personal or religious reasons.

Practical Takeaway: Understanding what domestic partnership actually is helps determine whether this legal status fits your needs. If you are an opposite-sex couple with at least one partner age 62 or older considering domestic partnership, research how the specific rights and responsibilities align with your family situation and financial goals.

Who Can Form a Domestic Partnership in California

California law restricts who may form a domestic partnership based on age, marital status, and sexual orientation. For opposite-sex couples, at least one partner must be 62 years of age or older. This restriction was implemented to distinguish domestic partnership from marriage for different-sex couples, since same-sex couples can now marry. If both partners in an opposite-sex couple are under 62, they cannot form a domestic partnership in California; marriage would be the only legal option if they wish to formalize their relationship.

Both partners must be at least 18 years old. California does not allow minors to enter into domestic partnerships, just as minors generally cannot marry without parental consent and court approval. Additionally, both partners must be free to enter into the relationship, meaning neither can currently be married to another person or already in an existing domestic partnership with someone else. This is the same requirement as for marriage.

Partners do not need to live together to register a domestic partnership, though they must be in a committed relationship. Unlike some states that require cohabitation for marriage or partnership recognition, California focuses on the parties' intent to form a committed relationship rather than where they physically reside. However, both partners must intend to assume the rights and responsibilities of domestic partners under California law.

Same-sex couples technically remain able to form domestic partnerships in California, but marriage is now the standard path for legal recognition of same-sex relationships. The state continues to recognize existing same-sex domestic partnerships and allows them to remain in that status if the couples choose not to convert to marriage. Some same-sex couples have maintained their domestic partnership status for personal, historical, or legal reasons specific to their situation.

Practical Takeaway: Before exploring California domestic partnership, verify that both partners meet the basic requirements. For opposite-sex couples, confirm that at least one partner is age 62 or older. For same-sex couples, understand that marriage is now available and may provide additional federal-level protections that domestic partnership cannot offer.

Steps to Register a Domestic Partnership

The registration process for California domestic partnership involves completing a specific state form and submitting it to the California Secretary of State. The form used is the Declaration of Domestic Partnership (Form DP-1). Both partners must sign this form, and it must be notarized by a notary public. This requirement ensures that both individuals are genuinely consenting to the partnership and that their identities are verified.

The process begins by obtaining the Declaration of Domestic Partnership form. This form is available on the California Secretary of State's website at sos.ca.gov. Partners can print the form directly or request a copy by mail. The form requires specific information about both partners: full legal names, dates of birth, Social Security numbers, California driver's license or identification card numbers, and addresses. Both partners must complete their sections of the form with accurate information, as any errors may delay registration or cause rejection.

Once the form is completed, both partners must appear before a notary public. The notary will verify that the people signing are who they claim to be by checking their identification documents. This step is mandatory—the Secretary of State will not accept the form without a notary's signature and seal. Notaries are available at banks, real estate offices, law offices, and through services like mobile notary companies. The cost for notarization typically ranges from $5 to $20 per signature, though fees vary by location and notary.

After notarization, one or both partners mail the completed form to the California Secretary of State, Elections Division. As of current processing times, the state typically processes domestic partnership registrations within 4 to 6 weeks. Partners should include a check or money order for the filing fee, which is currently $70. The state will mail a Certificate of Domestic Partnership once registration is complete. This certificate serves as proof of the legal partnership and can be used with employers, insurance companies, and government agencies.

Practical Takeaway: To register a domestic partnership, gather all required information beforehand, locate a notary in your area, and budget for the filing fee and notarization costs. Allow 4 to 6 weeks for the state to process the form and issue your certificate. Keep copies of the certificate for records related to insurance, healthcare decisions, and inheritance matters.

Legal Rights and Responsibilities of Domestic Partners

Once registered, domestic partners in California gain numerous legal rights that previously were available only to married couples. These rights encompass healthcare decisions, inheritance, property rights, and family law protections. Under California law, domestic partners have the right to make medical decisions for each other if one partner becomes incapacitated or unable to communicate. This includes hospital visitation rights, the authority to authorize medical procedures, and the ability to direct end-of-life care according to the partner's wishes.

Property and inheritance rights are significant. Domestic partners have the same community property rights as married couples. This means property acquired during the partnership is generally considered jointly owned, regardless of whose name is on the title. Upon the death of one partner, the surviving partner has inheritance rights if there is no valid will, similar to a surviving spouse. Additionally, domestic partners can transfer property between themselves without triggering certain property tax reassessments, which provides financial advantages in high-cost real estate markets like California.

Domestic partners can file as registered partners for California state income tax purposes. However, the federal government does not recognize domestic partnership for federal tax filing status. This creates a situation where partners file as a married couple filing jointly or separately to California, but must file as single or head of household to the Internal Revenue Service. This tax treatment requires careful attention and may necessitate working with a tax professional to avoid compliance issues.

Domestic partners also incur responsibilities. Both partners are responsible for each other's debts incurred during the partnership. If one partner passes away, the surviving partner may be liable for the deceased partner's outstanding obligations. Additionally, like married couples, domestic partners must go through a formal dissolution process if they wish to end the relationship; they cannot simply cease the partnership. Dissolution requires filing paperwork with the court and, if there are disputes over property or other matters, may involve litigation similar to divorce proceedings.

Practical Takeaway: Before registering as domestic partners, consult with an estate planning attorney about how the partnership affects your property, inheritance, and tax situation. Create or update your will, healthcare directive, and financial power of attorney to align with your domestic partnership status and ensure your wishes are legally documented and binding.

Dissolution of a Domestic Partnership

Ending a California domestic partnership is not a simple matter of filing paperwork to dissolve the relationship.
