Buying a home together in California: what to decide first

Buying with a spouse, registered domestic partner, friend or chosen family member? Before you fall for a house, talk about how you'll own it, pay for it and make decisions together.
Buying together doesn't always mean borrowing together, owning equal shares or making the same financial contribution. Work through who borrows, who owns, who pays, who makes decisions and what happens if plans change-before you're sitting down to sign.
Sorting out the details
What the paperwork actually does
The people on an offer, a mortgage and a deed may not be the same people-and even when they are, those documents do different jobs. Ask the lender, title or escrow officer and an attorney what each document means for your group.
- Title
- Who owns an interest in the property
- Loan
- Who promises the lender repayment
- Agreement
- How co-buyers propose to share expenses and decisions
- Estate documents
- Who may act or inherit, subject to applicable law
The four layers interact, but one document does not automatically settle the other three. Use the specialist comparison below before choosing terms.
The detailed comparison table scrolls horizontally; focus it and use the arrow keys for hidden columns.
| Document or arrangement | What it affects | Who to ask |
|---|---|---|
| Deed and form of title | Legal ownership and rights in the property | Title officer and qualified California attorney |
| Mortgage and loan documents | Who borrows and who is responsible for repayment | Lender |
| Co-ownership agreement | Contributions, decisions, exits and transfers, where appropriate | Property attorney |
| Estate and authority documents | Who may act or inherit if circumstances change | Estate-planning attorney |
California's Department of Real Estate explains that tenancy in common, joint tenancy and community property are different ownership concepts, with different consequences. For example, the right of survivorship associated with a joint tenancy is not the same as inheriting an interest held as a tenant in common. The appropriate choice depends on facts and law; a Realtor should not select a legal vesting arrangement for you. Read the Department of Real Estate's reference chapter on title.
An interest held as a tenant in common generally passes through the owner's estate rather than automatically to another co-owner; joint tenancy generally provides survivorship but may be severed. Community property and community property with right of survivorship are not interchangeable. Ask a California attorney to check deed language, the estate plan, any co-ownership agreement and lender obligations together.
Relationship status matters
Married, domestic partners or not legally partnered
Relationship status can affect rights and responsibilities, but it doesn't replace a discussion about the particular home, the deed and the financing.
Married or registered domestic partners
California states that registered domestic partners generally receive the same state-law rights and responsibilities as spouses. Ask a qualified California attorney about how that interacts with property characterization, vesting, taxes, dissolution and estate planning in your situation. Federal treatment can require separate advice. California Secretary of State: domestic-partnership FAQs.
Unmarried co-buyers or chosen family
Agree before closing on contributions, decisions about repairs and refinancing, occupancy, exits and how a share might be transferred. A property or estate attorney can explain when a written co-ownership agreement, a particular title arrangement or estate documents may be appropriate. Never assume that living together automatically creates an inheritance right.
Talk through the costs and the exit plan
Work out how the down payment, property taxes, insurance, maintenance, repairs and any special assessments will be shared. If contributions are unequal, record the arrangement and ask legal and tax professionals whether a contribution is treated as a gift, loan or ownership interest. A monthly budget needs more than the mortgage payment.
Talk about an exit while everyone still agrees: whether one person could buy out another, how a sale price would be determined, when a sale could happen and what refinancing would require. A qualified attorney can also explain whether powers of attorney, trusts or other documents are needed if someone dies or cannot act.
Decide who will communicate with the lender, title, escrow and inspector, and how each co-buyer wants to be addressed. Those practical details become important once deadlines begin.

The Marin-specific decision
Inspect the property and the total cost
Once the paperwork is sorted, the home still has to fit: cost, condition, insurance, drainage, commute and resale all matter. We compare Marin properties using the priorities you set-not assumptions about who you are or where you should live.
To understand the steps between an accepted offer and closing, see our escrow explainer. The lender, title officer and attorney still need to review your actual co-ownership documents.
