Buying a house before marriage: how should you hold title?

Last updated September 14, 2026

Title is the decision that matters, and marriage is what usually makes it for people. Two unmarried buyers cannot use California's community property vestings, so the deed has to say exactly what you mean. Choose joint tenancy or tenancy in common on purpose, record the shares that match the money, and pay an attorney to put the breakup terms in writing before you close. The loan is a separate question and it does not decide who owns the house.

Escrow asks how you want to hold title near the end of the process, often in a one page form with checkboxes. You will be tired, you will be signing a stack, and the question takes ten seconds to answer. It is the ten seconds with the longest reach of anything you sign that day.

How should an unmarried couple hold title in California?

There are four realistic answers for two people who are not married to each other. Read all four before escrow asks.

Joint tenancy is the one people land on when they have not thought about it, because it sounds tidy and it avoids probate. Tidy is the problem. Joint tenancy makes the shares equal whether or not the money was.

What is the difference between joint tenancy and tenancy in common?

Two differences do all the work. The shares, and what happens at a death.

Start with the shares. Joint tenancy is equal, always. If one of you brings most of the down payment and the deed records joint tenancy, half of that money changed hands the moment the deed recorded. Nobody announces it and no paperwork calls it a gift. The ownership is fifty fifty from that day. Tenancy in common is the vesting that can carry an uneven contribution on its face.

Now the death. Joint tenancy sends the house to the survivor with no court involved, ahead of any will. Tenancy in common sends each share wherever that owner's will or trust points it, and with no trust in place that usually means probate. Neither outcome is better in the abstract. They are just different, and only one of them matches your estate plan.

There is an income tax layer under both. At a death, only the share the deceased owner held gets a new cost basis for capital gains. Married couples who hold title as community property with right of survivorship can get a new basis on both halves, and unmarried buyers have no version of that. We wrote that up in community property with right of survivorship. Your CPA should be the one who applies it to you.

One more thing both vestings share. Either co-owner can file a partition action, which is a lawsuit asking a judge to divide the property or order it sold. It works. It is also slow, public, and expensive enough to eat the equity you are arguing over. The written agreement further down exists so that neither of you has to use it.

Does being on the loan put you on the deed?

No. Title and debt are two separate records, and mixing them up is the most common mistake we see at this stage.

If you both sign the note, you are each liable for the entire payment. A late payment lands on both credit reports. If one of you moves out, the lender has no interest in that fact and will keep expecting the full amount.

If only one of you signs the note, only that person carries the debt on their credit. The lender will still normally want the other owner to sign the deed of trust, because a lender wants its lien to cover the whole property rather than a share of it. Signing the deed of trust does not make that person a borrower. It pledges their ownership interest.

Plan for the exit while you are still getting along. Taking a name off a mortgage means refinancing, and the person staying has to qualify for the whole loan on their own income. Ask the lender now what that would take. Ask them too how they will treat two credit profiles on one application, because the weaker file usually sets the terms for both of you.

Before any of that, get the two numbers that decide the size of the house. Run Purchase Power for the price your income supports, then run the buyer net sheet for the cash it actually takes to close, which is the down payment plus every closing cost on top.

What should the written agreement cover?

Hire an attorney to draft a co-ownership agreement and sign it before escrow closes. An hour of legal time is a rounding error against the price of the house, and this is the document that decides what a breakup costs you.

Bring these items to that meeting already answered.

• The money in. Who paid the down payment and the closing costs, in dollars, and where each dollar came from. Gift funds from a parent belong in this list by name.
• The percentages. What share each of you owns, and whether that share moves if one of you later pays more than the other.
• The money out. Who pays the mortgage, the property taxes, the insurance, the HOA dues and the repairs, and in what proportion.
• The miss. What happens when one of you stops paying. Say whether the other can cover it and claim credit, and how that credit is measured.
• Who stays. If you split, who has the right to live in the house, for how long, and on what terms.
• The buyout formula. How value gets set, who picks the appraiser, what comes off the top, and the deadline to fund it.
• The backstop. What happens when neither of you can buy the other out. Usually the house is listed and both of you are obligated to sign.
• Death. What each of you wants for your share, matched to the vesting on the deed and to your wills or trusts.

Do not download a template for this. The value of the agreement is the lawyer who wrote it for your facts, and a form found online has no idea which of you brought the cash.

What happens to the house if you get married later?

Marriage does not move the deed. A home you owned before the wedding stays your separate property, and it stays vested exactly the way it was recorded. Nothing happens automatically on the wedding day.

What does happen is slower. When community earnings start paying down a loan on separate property, the community acquires an interest in the home, measured against the principal it paid down and a share of the appreciation that came with it. California lawyers call that the Moore and Marsden analysis, after the two cases that set it out. Separate property money put into community property has its own rule for reimbursement in Family Code section 2640. Both of these are worked out by family law attorneys with statements and escrow records in front of them, and neither is something you want to reconstruct from memory a decade later.

Keep the closing statement, the wire confirmations and the gift letters. Scan them and put them somewhere that survives a phone upgrade. Tracing is the whole game in these disputes, and it is won by paperwork.

If you marry and you want a different outcome, change the deed deliberately with an attorney. That is also the moment to look at whether community property with right of survivorship fits, since the basis treatment at a first death is the reason many California couples use it.

Does adding a partner to title reassess your property taxes?

It can, and this one surprises people. Transferring a share of ownership is a change in ownership for the share transferred, and the county assessor can reassess that share at today's market value. Your Proposition 13 base stays on the part you kept. The part you gave away comes back on the roll at current value and rises from there.

Transfers between spouses are a different story. Those are generally excluded from reassessment under Revenue and Taxation Code section 63, which is why the identical change made after a wedding usually does not touch the assessment. There is no equivalent exclusion for two people who are engaged.

Documentary transfer tax can also apply to the value of the interest transferred, depending on the facts and on whether there is consideration. Call the Los Angeles County or Ventura County Assessor before you record anything, and tell your escrow officer what you are trying to do. Exclusion forms, filing windows and local practice change, so get the current answer from the assessor rather than from a blog post.

This is not legal or tax advice. Vesting, basis, reimbursement rights, partition and reassessment all turn on documents and facts we cannot see, and registered domestic partners have their own set of rules. Use a real estate or estate planning attorney and a CPA before you sign a deed or change one.

What we watch go wrong here

Three failures show up over and over on this topic, and all three are cheap to prevent before closing.

• The silent gift. One buyer brings almost all of the cash and the deed records joint tenancy, because that was the box that got checked at escrow. Half of that cash became the other person's ownership that afternoon. Neither of them meant it and neither of them noticed.
• The handshake buyout. The relationship ends and both agree to work it out. A year later one is living in the house, the other is still on the loan, and the one who moved out cannot qualify to buy anything else because the full payment still counts against them.
• The refinance that never happens. The agreement says the person staying will refinance within six months. Nobody checked whether that person could qualify alone at any rate, and the answer turns out to be no. Ask the lender that question before you close, while it is still a hypothetical.

One honest limitation. We are real estate agents. We can show you what each vesting does, and we are in the room when the choice gets made, which is why we wrote this. We cannot draft your agreement, we cannot pick the vesting that fits your estate plan, and we are not going to pretend otherwise. Book the attorney hour before you are in escrow, when there is still time to change something.
