When Sarah and Miguel built their life together over 15 years in Auburn, they never thought about what would happen if one of them died. They shared a home, raised children, and considered themselves life partners in every way that mattered. But when Miguel suddenly passed away, Sarah discovered a harsh reality: California law treated her as a complete stranger to the man she’d loved for over a decade.
The home they’d shared together might go to Miguel’s distant relatives. His retirement accounts, which they’d always considered “theirs,” legally belonged to his family. Despite being his partner in every meaningful way, Sarah had no legal standing to make decisions or inherit anything.
This situation happens more often than many people realize. A large share of adults in the U.S. live with a partner outside of marriage at some point in their lives. Yet many of these couples don’t recognize that, without legal planning, they may have little to no protection if one partner passes away.
Why Marriage Creates Legal Protection (And What Happens Without It)
California takes inheritance law seriously, following strict rules about who gets what when someone dies. These rules strongly favor legal spouses and registered domestic partners. Since California doesn’t recognize common-law marriage, unmarried couples face significant legal barriers.
Marriage automatically grants you rights that unmarried couples must actively plan for:
- Automatic inheritance rights under California Probate Code Section 6401
- Community property rights to assets acquired during the relationship
- Medical decision-making authority during emergencies
- Social Security survivor benefits
- Favorable tax treatment for inherited assets
- Wrongful death claim rights
For unmarried couples, these protections simply don’t exist without intentional planning.
Can unmarried partners inherit anything automatically in California?
No, they cannot. California Probate Code Section 6400 controls what happens when someone dies without a will, creating a hierarchy of heirs that completely excludes unmarried partners. Your assets go to your surviving spouse, children, parents, siblings, or other blood relatives before your unmarried partner receives anything.
Even after living together for decades, sharing finances, and considering yourselves married in every way except legally, California law gives your partner no more inheritance rights than a stranger.
Domestic Partnership vs. Marriage: Understanding the Difference
California offers registered domestic partnership as an alternative to marriage, but couples don’t get it automatically by living together. You must actively register with the California Secretary of State to gain domestic partner status.
Registered domestic partnership provides many, but not all, rights of marriage. Here’s what registered domestic partners receive:
Rights You Get:
- Community property rights under California Family Code Section 297.5
- Inheritance rights identical to spouses under Probate Code Section 6401 (as provided by Family Code Section 297.5)
- Hospital visitation and medical decision-making rights
- Family and Medical Leave Act protections
- Spousal privilege in legal proceedings
Rights You Don’t Get:
- Federal tax benefits (domestic partnerships aren’t federally recognized)
- Social Security survivor benefits
- Immigration benefits for non-citizen partners
- Federal family leave protections
Who can become registered domestic partners in California?
To register as domestic partners in California, you must meet these requirements:
- Both people must be 18 or older
- Neither person can be married or in another domestic partnership
- You cannot be related by blood in a way that would prevent marriage
- Both must be capable of consenting to the domestic partnership
- Both must file a Declaration of Domestic Partnership with the California Secretary of State
Same-sex and opposite-sex couples have the same domestic partnership rights in California.
Essential Estate Planning Tools for Unmarried Couples
Without marriage’s automatic protections, unmarried couples must be more intentional about their planning. Here are the fundamental tools you need:
Wills and Trust Documents
A will provides your most basic protection, but it’s often not enough by itself. California’s probate process typically takes 12-18 months and costs 4-7% of your estate’s value.
Living Trusts offer several advantages:
- Assets pass directly to beneficiaries without probate
- Privacy protection (probate proceedings become public record)
- Faster distribution of assets
- Reduced costs and court involvement
When creating your will or trust, be specific about your intentions. Don’t just name your partner as a beneficiary – explain the relationship and your reasons for leaving assets to them. This helps prevent family members from challenging your wishes.
Financial Powers of Attorney
A Financial Power of Attorney allows your partner to manage your finances if you become unable to do so yourself. Without this document, your partner has no legal authority to pay bills, access accounts, or make financial decisions on your behalf.
California Probate Code Sections 4000-4545 govern powers of attorney. Your document should be:
- Durable (remains valid if you become incapacitated)
- Broad enough to cover all necessary financial decisions
- Specific about timing (immediate vs. taking effect upon incapacity)
Advance Healthcare Directives
Medical professionals can legally exclude your unmarried partner from treatment decisions unless you have proper documentation. An Advance Healthcare Directive combines two important documents:
Healthcare Power of Attorney. Names your partner as your healthcare agent to make medical decisions when you cannot.
Living Will. States your preferences for end-of-life care, including wishes about life support, artificial nutrition, and pain management.
California Probate Code Section 4670 requires specific language and witness requirements for these documents to be valid.
HIPAA Authorization Forms
The Health Insurance Portability and Accountability Act (HIPAA) prevents healthcare providers from sharing medical information with anyone not specifically authorized. A HIPAA authorization form ensures your partner can access your medical information and communicate with your healthcare providers.
Property Ownership Strategies for Unmarried Couples
How you hold title to property significantly impacts what happens when one partner dies. California offers several options:
Joint Tenancy with Right of Survivorship
This works well for unmarried couples buying property together. When one joint tenant dies, their share automatically passes to the surviving joint tenant, bypassing probate entirely. Key features include:
- Both owners have equal rights to the entire property
- Cannot be willed to someone else
- Automatic transfer upon death
- Creditors of one owner can potentially reach the property
Tenancy in Common
With tenancy in common, each owner holds a specific percentage interest that can be willed to anyone. This might work better if:
- Partners contribute unequally to the purchase
- You want flexibility to leave your share to children from a previous relationship
- You want to maintain separate ownership interests
Community Property with Right of Survivorship
This option is only available to married couples and registered domestic partners, not unmarried couples.
How do unmarried couples handle retirement accounts and life insurance?
Retirement accounts and life insurance policies pass by beneficiary designation, not through your will. This makes them powerful tools for unmarried couples because they bypass probate and go directly to your named beneficiaries.
401(k) and IRA Accounts. Name your partner as the primary beneficiary. Without marriage, your partner won’t have the same rollover options as a spouse, but they can still inherit the accounts.
Life Insurance. This often provides the most cost-effective way to give financial security to your partner. Life insurance proceeds are generally tax-free to beneficiaries and don’t go through probate.
Pension Benefits. Many pension plans only provide survivor benefits to legal spouses. Check with your plan administrator about options for unmarried partners.
Tax Implications You Should Know
Unmarried couples face different tax consequences than married couples when it comes to inheritance:
Step-Up in Basis. When a spouse inherits property, they receive a “stepped-up basis” equal to the property’s fair market value at death. Unmarried partners also receive this benefit, which can reduce capital gains taxes if they later sell the property.
Estate Tax Exemption. The 2025 federal estate tax exemption is $13.99 million per person. Assets left to a spouse are generally exempt from estate taxes regardless of amount (unlimited marital deduction). Unmarried partners don’t get this benefit, but few estates are large enough for this to matter.
Gift Tax Issues. Married couples can gift unlimited amounts to each other. Unmarried partners are limited to the annual gift tax exclusion ($19,000 for 2025) before gift tax consequences arise.
Protecting Your Children from Previous Relationships
Blended families create additional complications for unmarried couples. If you have children from a previous relationship, you need to balance providing for your current partner while ensuring your children’s inheritance rights.
Common Solutions:
- Life insurance to provide immediate funds for your partner
- Trust structures that provide income to your partner for life, then distribute principal to your children
- Separate assets designated for children vs. partner
- Clear documentation of your intentions to prevent family disputes
California Probate Code Section 21620 provides that a child is entitled to support from a parent’s estate, which could complicate plans to leave everything to an unmarried partner.
What happens if we break up? Protecting yourself in estate planning
Unlike married couples who have established divorce procedures, unmarried couples must think carefully about what happens if the relationship ends. Your estate planning documents should address this possibility:
Automatic Revocation Clauses. Include language that automatically revokes benefits to your partner if you break up or stop living together.
Regular Review Requirements. Set calendar reminders to review and update your documents regularly, especially after major relationship changes.
Separate Property Documentation. Keep clear records of separate vs. joint assets to avoid disputes later.
Common Mistakes Unmarried Couples Make
Assuming Living Together Creates Legal Rights
Simply living together doesn’t create any legal rights in California. You must take active steps to protect each other.
Naming Each Other on Bank Accounts Without Understanding the Consequences
Joint bank accounts create the right of survivorship, but they also give both parties access to all funds and can create gift tax issues.
Forgetting to Update Beneficiary Designations
Your retirement accounts and life insurance policies won’t be covered by your will if you name someone else as beneficiary.
Not Planning for Incapacity
Death planning matters, but planning for disability or incapacity is equally important for unmarried couples.
Failing to Communicate with Family
Your blood relatives may be shocked to learn about your plans. Consider having conversations with adult children and other family members about your intentions.
Getting Professional Help with Your Estate Plan
While some basic documents can be created online, unmarried couples often face complex situations that benefit from professional guidance. Consider working with an estate planning attorney when:
- You own significant assets or real property
- Either partner has children from previous relationships
- Your relationship involves business ownership or professional practices
- You have concerns about family members challenging your plans
- Tax planning is important due to the size of your estate
- You need coordination between multiple states (if you’ve lived in different states)
Key Takeaways

- With proper planning, unmarried couples can achieve most of the same protections as married couples through wills, trusts, powers of attorney, and beneficiary designations
- Domestic partnership registration provides many marriage-like rights but requires active registration with the California Secretary of State
- Property ownership structure (joint tenancy vs. tenancy in common) significantly affects inheritance rights
- Retirement accounts and life insurance pass by beneficiary designation, making them powerful tools for unmarried couples
- Regular review and updates of estate planning documents are essential as relationships and finances evolve
- Professional guidance becomes more valuable when significant assets, children from previous relationships, or complex family dynamics are involved
Frequently Asked Questions
Q: Do we need separate estate plans or can we do one together? Each person needs their own individual estate planning documents. You cannot share a will or power of attorney, though you can coordinate your plans to work together effectively.
Q: Can my partner’s family challenge my estate plan? Yes, family members can contest wills and other estate planning documents, especially if they feel an “outsider” is receiving assets they believe should stay in the family. Proper documentation and legal assistance can help prevent successful challenges.
Q: What happens to our house if we own it together and one of us dies? This depends on how you hold the title. Joint tenancy with right of survivorship automatically transfers your share to your partner. Tenancy in common allows you to will your share to anyone, including someone other than your partner.
Q: Should we get married just for the legal benefits? Marriage does provide automatic legal protections that unmarried couples must plan around. However, marriage also creates legal obligations and potential complications in divorce. The decision should be based on your personal values and relationship goals, not just legal convenience.
Q: How often should we update our estate planning documents? Review your estate plan annually and update it after major life events like buying property, having children, starting a business, or significant changes in your relationship status.
Q: Can we create an “unmarried couple agreement” to define our rights? Yes, cohabitation agreements can define financial responsibilities, property rights, and expectations during your relationship and if it ends. These agreements work alongside, not instead of, your estate planning documents.
