Two friends buying together. Siblings pooling an inheritance into a house. An unmarried couple. A parent contributing to a child's purchase and taking an interest in return.
Shared ownership is common and escrow handles it without difficulty. What escrow cannot do is settle the questions the co-buyers have not answered between themselves, and those questions have a habit of surfacing on signing day when there is no time left to think.
This is what escrow needs, and what belongs on paper before it asks.
Escrow follows written instruction from both
The first structural point: when two people buy together, BOTH are principals. Escrow takes instruction from both, requires both to sign, and cannot act on one buyer's direction over the other's silence or objection.
That is not bureaucracy; it is the neutrality that makes escrow useful. It does mean that if the two buyers disagree mid-transaction, escrow stops rather than picking a side - the same posture that produces the standoff described in the disputes and mediation guide. Two buyers who cannot agree are two buyers whose escrow does not move.
The practical version: decide things between yourselves, then instruct escrow jointly and in writing.
The vesting decision
How two or more buyers hold title is a decision with genuine legal and estate consequences, and California recognizes several forms. Each affects what happens to a co-owner's share on death, what a co-owner can do with their interest independently, and how the ownership is treated for other purposes.
There is no default that is right for everyone, and the correct choice depends on the relationship, the contributions, and the estate plans involved. It is a question for an attorney, and where money is unequal, for a CPA as well.
What matters mechanically is that the ANSWER MUST BE EXACT and must be given to escrow in writing before the deed is prepared. The deed states the vesting, and it is the document that governs afterward. Changing it later requires a new recorded instrument and everyone's cooperation. Read the deed before signing, not after recording.
Unequal contributions need documenting somewhere
Two buyers rarely contribute identically. One brings a larger down payment. One pays more of the monthly cost. One funds the renovation. One is on the loan and the other is not.
Here is the thing people are surprised by: THE DEED DOES NOT RECORD ANY OF THAT. The vesting states the form of ownership; it does not narrate who paid what. Nor does the settlement statement, which reports what arrived in escrow rather than any agreement about what it means.
So if the co-buyers intend anything other than what their vesting implies, that intention lives in a separate written agreement between them - drafted with an attorney, before closing. A co-ownership agreement typically addresses contributions, how ongoing costs are shared, what happens if one wants out, how a sale is decided, how a buyout is valued, and what occurs on death or default.
It is an unromantic document and it is the single most valuable thing co-buyers can produce. Its whole purpose is to be written while everyone is agreeable.
Funds from two sources
Escrow verifies who sends money, and two buyers means two verification paths.
Tell escrow in advance that funds will arrive from more than one account, from whom, and roughly when. Money arriving from an account belonging to someone not on the transaction - a parent, a business, a third party - raises questions escrow must resolve before closing, and resolving them takes time nobody has that week. If a family member is contributing, say so early; the treatment differs depending on whether it is a gift, a loan, or a purchase of an interest, and where there is a mortgage the LENDER has documentation requirements of its own.
Ask the lender in writing how it wants a contribution documented, because the answer affects eligibility on some programs.
The mechanics of collection apply to both buyers equally: escrow disburses from collected funds, so both parties need to hit the deadline. One buyer's late wire delays everyone's closing.
And the constant, which matters more here than in a single-buyer purchase: VERIFY WIRING INSTRUCTIONS BY TELEPHONE using a number obtained independently, never a number printed in an email. With two buyers, instructions get forwarded between them, and a forwarded instruction feels verified because it came from someone trusted. It is not verified. Each person who sends money makes their own call to the escrow company on its published number and reads the details back. The deposit guide covers the same discipline for the first transfer.
Signing and logistics
Both buyers sign, and on a financed purchase both borrowers sign the loan documents. If one cannot be present, plan that in the first week rather than the last - the options are a separate signing appointment or a power of attorney, and a power of attorney requires approval from escrow, title, and the lender before it can be relied on.
The escrow glossary covers the vocabulary both buyers will encounter, which is worth reading together rather than separately.
The order of operations
Decide the vesting with an attorney. Write the co-ownership agreement before closing. Confirm with the lender how contributions must be documented. Tell escrow about multiple funding sources early. Give escrow the exact vesting in writing. Sign jointly, and instruct jointly.
Vesting and co-ownership terms go to an attorney. Contribution treatment goes to a CPA and the lender. Funding logistics go to the escrow officer.

Frequently asked questions
Do both co-buyers have to sign everything in escrow?
Yes. When two people buy together both are principals, so escrow takes instruction from both and cannot act on one buyer's direction over the other's objection or silence. Two buyers who cannot agree are two buyers whose escrow stops moving.
Does the deed show who paid what?
No. The vesting states the form of ownership; it does not record who contributed which amount, and the settlement statement reports what arrived in escrow rather than any agreement about what it means. Unequal contributions belong in a separate written co-ownership agreement.
What should a co-ownership agreement cover?
Contributions, how ongoing costs are shared, what happens if one owner wants out, how a sale is decided, how a buyout is valued, and what occurs on death or default. Draft it with an attorney before closing, while everyone is still agreeable.
Can funds come from two different accounts?
Yes, but tell escrow in advance who is sending from where. Money arriving from an account belonging to someone not on the transaction raises questions that must be resolved before closing, and where there is a mortgage the lender has its own documentation requirements for contributions.
