Splitting Security Deposits With Roommates

On a joint lease, the landlord holds one deposit for the whole unit, can apply it to damage or unpaid rent no matter which roommate caused it, and generally does not have to return any of it until the tenancy ends and everyone has moved out. California, since January 1, 2026, and Virginia require the refund to go out as one check payable to all the tenants unless every tenant agrees in writing to a different arrangement. How the money divides among you is for the roommates to settle, so write down each person's share and how deductions will be split before you move in.

How one deposit works on a joint lease

A joint lease is a single lease that every roommate signs with the landlord. Michigan Legal Help, a statewide legal self-help site, explains that these leases usually make each roommate "jointly and severally liable," meaning each of you is fully responsible for the rent and any damage to the home. The landlord can ask any one roommate for all of it, even if the roommates agreed to pay only their own shares and even if only one roommate caused the problem.

For the deposit, that means:

• Deductions come out of the whole deposit. If one roommate's guest breaks a window, the landlord takes the repair cost from the deposit everyone paid into, not from that roommate's contribution.
• Any of you can owe charges above the deposit. If damage or unpaid rent costs more than the deposit, the landlord can pursue any of you for the rest. See our guide to whether you are liable for a roommate's damage.
• Your roommate agreement does not bind the landlord. The landlord is not a party to it, so it governs only what you owe each other.

If each of you signed your own lease with the landlord, this article does not describe your situation; see our guide to joint leases vs. individual leases.

Who gets the refund check?

• California: when more than one adult tenant lives in the unit, the landlord must return the balance by a check made payable to all adult tenants on the lease when the tenancy ends, and can send the itemized statement (its list of deductions) to any one of them. To change that, the landlord and every adult tenant can sign a written agreement, at the start of the tenancy or any time later, saying how the money will be returned (to one tenant, or divided among you with set percentages, by check or by deposit to each person's account) and how each of you will receive the itemized statement.
• Virginia: the landlord sends one check payable to all tenants on the lease, to a forwarding address that one of you provides, within 45 days, unless each tenant agrees otherwise in writing. Without a forwarding address, the landlord can keep holding the deposit.
• Elsewhere: check your lease and your state's deposit law. If neither addresses it, ask the landlord in writing before move-out whether it will write separate checks according to your agreement.

A check made out to all of you jointly can be cashed or deposited only by all of you acting together, under the standard rule for checks in Uniform Commercial Code section 3-110. Decide in advance who will deposit it, how the others will sign, and how quickly that person pays out the other shares. Our overview of state security deposit laws explains how return deadlines and penalties vary by state.

How to record shares and split deductions

Put these points in a written roommate agreement that everyone signs:

1. What each person paid. List each contribution and how it was paid, and keep the bank or payment-app record.
2. How the refund divides. Divide it in proportion to what each person paid, unless you agree on something else.
3. How deductions divide. For example, assign damage inside a bedroom to that room's occupant, divide shared-area damage and cleaning in proportion to each share, and charge unpaid rent to whoever did not pay it.
4. Who handles the check. Name the person who will receive or deposit it and set a deadline, such as 7 days, to pay out the other shares.
5. Move-in photos for each room. Photograph every bedroom and shared space before anyone moves in and share the files with everyone.

See also our guide to creating a roommate agreement. In California, you can also turn your split into the written agreement with the landlord described above, so the landlord pays each of you directly.

Worked example: three roommates pay a $3,000 deposit: Alex pays $1,200 for the larger room, and Blake and Casey pay $900 each. At move-out, the landlord deducts $400 to replace the closet door in Alex's room and $240 to clean the kitchen.

The refund is $2,360 ($3,000 - $400 - $240), and the three shares add up to it. If a charge looks wrong, dispute it with the landlord before you divide anything; our guide to understanding security deposit deductions explains which charges are allowed.

When a roommate moves out before the lease ends

The landlord generally does not have to return any part of the deposit until the lease ends and all of the original tenants have moved out. A roommate who leaves early gets their share back sooner only if the roommates staying or a replacement agree to buy it out; otherwise they wait for the final refund. In California, the refund check goes to the adult tenants on the lease when the tenancy ends, so a roommate who has been taken off the lease will not be on it.

Leaving also does not end the departing roommate's duties under a joint lease, and neither does the landlord's approval of a replacement. California's tenant guide explains that a tenant who transfers their place in a lease to someone else stays responsible to the landlord unless the landlord explicitly releases them, and that a full release takes a written agreement among the landlord, the departing tenant, and the new tenant. In practice, landlords typically have everyone sign a new lease with the replacement.

To buy out a departing roommate's share:

1. Walk through together. Inspect the departing roommate's room and the shared areas, take photos, and get estimates for anything the landlord would charge for.
2. Agree on the amount. Start with what that roommate paid toward the deposit and subtract the repair costs you agreed on.
3. Pay the departing roommate directly. The incoming roommate, or the roommates staying, pays that amount to the person leaving. The landlord keeps the full deposit.
4. Put the transfer in writing. The departing roommate signs a statement that the payer now holds the claim to that share of the deposit.
5. Get a written release. Ask the landlord to approve the replacement and to sign a new lease or amendment that releases the departing roommate. In California, also update any written deposit agreement with the landlord so the refund goes to the right people.

For example, if the departing roommate paid $900 toward the deposit and you agree that a hole in her bedroom wall will cost $150 to repair, the buyout is $750 ($900 - $150). A departing roommate who waits for the final refund instead shares in any deductions for damage done after she left, unless your agreement assigns those costs to the roommates who stayed.
