Roommates and Co-Tenants in Texas Rentals: Joint and Several Liability, One Lease, and What Happens When Someone Leaves

If three names appear on a Texas lease and one roommate stops paying, the landlord can collect the full rent from either of the other two. That is joint and several liability, and it is the default on almost every multi-tenant lease signed in Bexar County. Your "share" is a private arrangement between roommates. It is not binding on the landlord, and it will not stop an eviction filed in a Bexar County JP court.

That single rule drives almost every roommate problem in San Antonio rentals — from the UTSA-area four-bedrooms around 78249, to the shared Southtown bungalows in 78204, to the military roommates splitting a Converse or Universal City house near JBSA-Randolph. Here is how it actually works, and the specific moves that protect you when someone wants out.

What "joint and several" actually means on your lease

Texas residential leases almost always include a clause stating that each tenant is "jointly and severally liable" for the full rent and for any damage. The TAA (Texas Apartment Association) lease — used by most managed properties in San Antonio — includes this language by default. Even most private landlord leases copy it.

In practice:

• The landlord can demand 100% of the rent from any one of you. They do not have to chase everyone equally.
• If one roommate trashes a bedroom, the deposit deduction comes out of the single deposit paid for the unit — not just that person's share.
• An eviction petition filed under Texas Property Code § 24.0051 names every tenant on the lease. A judgment runs against all of you.
• A judgment that goes to collections or a tenant screening database follows every signer, not just the one who stopped paying.

The landlord does not care which of you actually owes what. That is your problem to sort out — in small claims court if it comes to it, under a separate contract theory between roommates.

The three ways people end up on the lease together

The legal picture changes depending on how the arrangement was set up at signing.

1. Co-tenants (all names on one lease)

This is the standard San Antonio arrangement. Everyone signed the same document, everyone is a tenant, everyone has full rights to the unit and full liability for the rent. No one roommate can lock another out — that would violate § 92.0081, the same lockout statute that controls landlord behavior.

2. Separate per-bedroom leases

Common in purpose-built student housing near UTSA and in some corporate rent-by-the-room setups. Each tenant signs their own lease for a bedroom plus shared common areas. One person's default does not legally touch the others. If you are a UTSA student weighing a by-the-bed lease against a shared traditional lease, the risk calculus is completely different.

3. One leaseholder plus an unauthorized occupant

If only your name is on the lease and your partner or friend moves in, they are not a tenant. They have no right to be there if you leave, and the landlord can treat their presence as a lease violation under the unauthorized-occupant clause (standard in TAA leases). You are 100% liable; they are legally a guest. This arrangement is the single most common cause of ugly roommate exits in San Antonio.

When one roommate wants to leave mid-lease

There is no statute that lets a co-tenant unilaterally remove themselves from a Texas lease. The lease is a contract. Walking out of the apartment does not walk you out of the obligation.

There are a few real paths:

• Landlord releases the leaving tenant in writing. This requires the landlord's consent. Most managed properties will do it only if a replacement tenant signs on and passes screening — effectively a lease assignment under Texas Property Code § 91.005, which prohibits subletting or assignment without landlord consent.
• Lease amendment removing one name. Usually documented on a form like TREC-style amendment or an in-house addendum. The remaining roommates re-qualify at the current income threshold (typically 3x rent in San Antonio managed properties). The departing roommate's deposit interest is handled between the roommates — the landlord keeps the original deposit intact until final move-out.
• Military clause (SCRA, 50 U.S.C. § 3955). A servicemember roommate with PCS orders or 90-plus-day deployment orders can terminate their own obligation with 30 days' notice after the next rent due date. Critical point: § 3955 terminates the lease for the servicemember only when they are the sole tenant. When there are civilian co-tenants, courts have generally held the lease continues for the civilians, who remain liable. Get this in writing from the landlord before anyone counts on it.
• Family violence exit under Texas Property Code § 92.0161. A tenant with a protective order or qualifying documentation can terminate their own tenancy with 30 days' notice. The other co-tenants remain on the lease unless they independently qualify.
• Buy out the lease. Pay the reletting fee (capped at a reasonable amount under § 92.302's mitigation rules) or negotiate a lump sum. Done cleanly, this ends liability for everyone.

The worst move — and the most common — is the leaving roommate just stops Venmoing their share and assumes "not my problem anymore." It is still their problem. The landlord will sue all signers.

Security deposits with multiple tenants

There is one security deposit for the unit, held in one ledger. Under Texas Property Code § 92.103, the landlord has 30 days after everyone surrenders the unit — the final move-out — to return it with an itemized statement of deductions.

Some specifics that trip people up:

• The landlord does not have to refund the leaving roommate's share when they leave mid-lease. They hold the full deposit until the unit is vacated at the end of the term.
• The landlord sends one check, typically to the "forwarding address" provided by the tenants. If the roommates do not agree on where it goes, the landlord's safest move is to issue it jointly to all original signers.
• Any deduction for damage, cleaning, or unpaid rent comes out of the pooled deposit regardless of who caused it. Internal reimbursement among roommates is a separate dispute.
• If the landlord withholds in bad faith, the treble damages plus $100 plus attorney's fees under § 92.109 belong to the tenants collectively — not to one roommate.

Before anyone moves out mid-lease, take dated photos of every room (including the departing roommate's bedroom) and email them to all parties. This is the only reliable way to allocate damage later.

Notice to terminate and month-to-month conversions

When a fixed-term lease rolls to month-to-month in San Antonio, Texas Property Code § 91.001 governs the notice to terminate: at least one full rental period, in writing, unless the lease specifies longer. Many TAA leases require 60 days.

With co-tenants, notice from one is not notice from all unless the lease says so. If you want out and your roommate does not, your written notice does not end the lease for the household — the landlord may treat it as your personal abandonment and continue collecting from the remaining tenant.

What most people get wrong

• "I moved out, so I'm off the lease." No. Physical departure does not terminate contractual liability. Until the landlord signs a release or the lease ends, you owe rent.
• "The lease says we each pay $600, so I only owe my $600." That allocation is between you. The landlord's contract is for the full $1,800, collectible from any signer. Check the "joint and several" clause — it is almost always there.
• "My roommate's name isn't on the lease, so they can stay if I leave." They cannot. An unauthorized occupant with no leaseholder is a trespasser to the landlord. They can be removed, and you remain liable for rent until the term ends.
• "We'll just change the locks on the bad roommate." Illegal. Co-tenants have equal possessory rights. Changing locks on a lease signer is a civil lockout and exposes you to the same damages a landlord would face under § 92.0081 — a civil penalty plus one month's rent plus actual damages plus attorney's fees.
• "Military clause ends the lease for everyone." It ends it for the servicemember. Civilian co-tenants typically remain on the hook. Confirm with the landlord in writing before the civilians make plans.
• "The eviction only goes on the one who didn't pay." It goes on every named defendant. An eviction judgment in a Bexar County JP court shows up on tenant screening reports for every tenant on the lease, which is why clean co-tenants have been locked out of their next rental over a roommate they haven't seen in months.

Protect yourself before you sign

• Insist on a written roommate agreement — separate from the lease — that specifies rent shares, utility shares, deposit shares, and what happens if someone wants out early. This is enforceable between roommates even if the landlord ignores it.
• Confirm in writing that the landlord will consider a replacement tenant and what the screening criteria are. Get the current income multiplier and the credit threshold.
• Keep a shared folder with the lease, deposit receipt, move-in condition form (required under § 92.103 to be delivered), and photos of every room on day one.
• Pay your share directly to the landlord when possible — a separate ACH or portal payment per tenant creates a paper trail if things fall apart.
• Renters insurance costs about $12 to $20 a month in San Antonio and covers your personal property regardless of what a roommate does. Get a policy in your own name.

If you are weighing a shared San Antonio rental against a solo unit, the trade-off is cheaper rent against the risk of being on the hook for someone else's choices. RentInSA's active listings as of October 2026 show a median asking rent of $1,700 a month across the metro, with 4,773 active rentals available — enough inventory that going solo in a smaller one-bedroom is often a realistic alternative to splitting a three-bedroom with people you barely know.
