This guide explains what a domestic partnership is in California, how you register it with the California Secretary of State, and what changes you can and can’t make after filing. You’ll also learn the big legal differences from marriage, especially under federal law and taxes.
Domestic partnership in California explained simply
A domestic partnership in California is a legal union between two adults who share an intimate and committed life and register it with the state. In California law, registered partners generally get rights and benefits similar to those of spouses, and they also take on similar responsibilities under state law.
Key idea to remember
If you want the state-level legal protections, it’s not enough to just live together. You must register the partnership with the state.
Domestic partnership vs marriage in California
Under California law, registered domestic partners generally receive many of the same state protections and duties as married spouses. The main difference is federal recognition.
Quick comparison
| Topic | Registered domestic partnership in California | Marriage in California |
|---|---|---|
| California legal recognition | Yes. Registered domestic partnership is recognized under state law | Yes |
| Federal recognition | Not always the same as marriage | Generally treated as marriage under federal law |
| Federal taxes | Registered partners are not treated as married for federal tax purposes (important example used by the California Secretary of State materials) | Treated as married for federal tax purposes |
| Same-sex couples | Still allowed as an option | Allowed since marriage is legal nationwide |
Pain point to imagine: You might do everything right in California and still discover that the federal government does not treat your union the same way. That can affect tax filing and some federal programs.
Registration with the California Secretary of State
California requires state registration to get state-level legal benefits. Registration through a county or city is not the same as registering with the Secretary of State.
State registration is different from local registration
| Registration type | Are you entitled to California domestic partnership law benefits? |
|---|---|
| Registered with California Secretary of State | Yes |
| Registered only with a city or county | No |
Who can register in California
To be eligible, both partners must meet requirements at the time of filing:
- Neither person is married to someone else, and neither is in another domestic partnership that hasn’t been ended.
- The two people are not closely related by blood in a way that would prevent marriage in California.
- Both are at least 18 years old, unless an exception applies.
- Both are capable of consenting.
Age exception
If someone is under 18, they may still be able to register if they get a court order that grants permission. California points to California Family Code section 297.1 for how that works.
How to register a domestic partnership step by step
What you must do
You register by filing a declaration form with the Secretary of State and meeting signature rules.
1. Complete the correct declaration form
- Use a Declaration of Domestic Partnership for a public domestic partnership.
- Use a Confidential Declaration of Domestic Partnership for a confidential one.
2. Use wet signatures and notary acknowledgement
The original declaration with wet signatures by both partners is required. Copies or scans are not accepted.
3. Notary and signature rules
A big practical detail is that both partners must sign the same form, and each signature must be acknowledged by a notary.
4. Submit it to the Secretary of State
The Secretary of State materials state that you submit the completed form and fees for filing. Also note:
- Fax or email submission is not accepted for domestic partnership registrations (or terminations/revocations).
If a partner can’t appear in person
Imagine one partner is incarcerated or is outside California (or outside the country). California still allows registration if both partners complete the same form correctly.
Practical options described by the state
- Each partner may separately sign the same form.
- Then each partner must appear before a notary public to have their signature acknowledged.
- Notarizations done outside California are allowed if they follow the rules of that location.
- Important rule: separate forms that contain only one partner’s signature are not accepted. Both partners must complete the same document.
Public vs confidential domestic partnerships
California uses two types of filings: public and confidential. This mainly affects who can access records.
Main difference
| Record type | Is it open to the public | Who can get information |
|---|---|---|
| Public domestic partnership | Yes. Names and mailing address are open to inspection | Public access generally allowed |
| Confidential domestic partnership | No. Not open to public inspection | Information generally only to partners after identity verification, or via a court order with good cause |
Pain point to imagine: If you worry about privacy, the “public record” difference can feel huge—especially when name and contact information are involved.
A key operational detail
Requests for confidential domestic partnership status or information can’t be provided by phone or email, and the process depends on verification or a court order.
Name changes during registration
Partners can change their names when they register, but not freely.
Permissible name change options
One or both partners may adopt certain middle or last names, including:
- The other partner’s current last name
- Their own last name given at birth
- A combined last name that uses segments from birth last names
- A hyphenated combination of last names
If you make a mistake before filing
If you realize something is wrong on the declaration before filing, the state recommends:
- Complete a new form.
If both partners already signed and the signatures were acknowledged by a notary, you generally cannot change information on the already-notarized declaration. Instead, you must complete a new declaration and repeat signing and notary acknowledgement.
What paperwork you receive after filing
After your domestic partnership is filed:
- Partners receive one copy of the file-stamped declaration (uncertified).
- Partners also receive a Certificate of Registration of Domestic Partnership.
Additional certified or uncertified copies can be purchased at the time of registration.
About certificates and seals
The state notes that as of September 2014, it no longer issues certificates with a raised gold seal. The certificate is provided upon filing and is described as ornamental and not for substantiation of the domestic partnership. For proof, use a certified copy of the filed declaration.
Proof of partnership and certified copies
For proof, the state says a certified copy of the filed, file-stamped declaration is sufficient.
How a certified copy looks
Certified copies contain a purple stamp on the back with the California State Seal and initials.
How to order records
You can order copies by submitting a special filings records order form. The confidential option uses the confidential records order process.
If you change names after filing
Here is a common surprise:
- There is no legal provision to update the state registry to reflect later legal name changes for domestic partners.
So, any later changes won’t appear in the domestic partners registry.
Ending a domestic partnership in California
Ending a domestic partnership can be done two different ways depending on whether state termination requirements are met.
Option A. Terminate with the Secretary of State
If both partners meet all requirements in California Family Code section 299(a), the partnership may be terminated by filing a Notice of Termination of Domestic Partnership with the Secretary of State.
Rules the state highlights:
- The original notice with wet signatures by both partners is required.
- Fax or scans are not accepted.
Option B. Dissolve in Superior Court
If the partners do not meet the requirements for termination through the Secretary of State, then they must dissolve through California Superior Court.
Can a termination be undone
If partners change their minds about termination filed with the Secretary of State, undoing it may not be straightforward. In practice, outcomes depend on the situation and timing, so legal guidance is important when this happens.
Property and support during ending a partnership
California domestic partnerships come with ongoing obligations, including rules that can affect property division and financial support when the relationship ends.
What this means in real life
- Assets and debts built during the partnership may be treated under California community property concepts (so the division can feel similar to divorce).
- In some cases, one partner may owe financial support to the other.
Pain point to imagine: If you and your partner used the domestic partnership to share finances—bank accounts, housing, retirement planning—ending the partnership can trigger a need for a careful accounting of property and responsibilities.
Alternatives to dispute resolution
When ending a domestic partnership, many couples choose ways to resolve disagreements without a full courtroom battle.
Common options
- Mediation
- Collaborative approaches
These methods can help couples talk through issues like property and support in a more structured way than trying to negotiate in conflict.

Federal and healthcare implications
Federal recognition
California domestic partnership recognition does not always match marriage under federal law. The Secretary of State materials specifically point out that registered domestic partners are not considered married for federal tax purposes.
Healthcare decisions
Registered partners generally have legal standing to make healthcare decisions in certain circumstances when one partner is incapacitated, similar to spouses under California law.
Recognition beyond California
California may recognize substantially similar unions from other states or foreign jurisdictions as domestic partnerships if the other jurisdiction’s union law is comparable.
Important caution: Not every “similar” arrangement is strong enough to be treated the same way in California. The strength and structure of the legal union matter.
A practical checklist for registration
| Step | What to do | Common mistake to avoid |
|---|---|---|
| Eligibility | Confirm neither partner is married/another unended partnership and both can consent | Registering when someone is still legally married |
| Form | Use the right declaration type | Using copies or scans instead of originals |
| Signatures | Both partners sign the same form with wet signatures | Signing separate forms |
| Notary | Get signatures acknowledged by a notary | Missing required notary acknowledgement |
| Submission | Mail or file with Secretary of State (no fax/email) | Expecting fax/email approval |
| Proof later | Plan for certified copies of the file-stamped declaration | Using only the ornamental certificate |
Summary
A domestic partnership in California is a state-registered union for two partners who share an intimate life. It provides many rights under California state law that are similar to marriage, but it differs at the federal level—especially for tax purposes. Registration is done through the Secretary of State with strict document and notary rules, and you can choose public or confidential records depending on privacy needs. Ending it may be handled by state termination filings or by court dissolution, depending on eligibility.
