Consumer Legal Issue
My roommate moved out early, and I took over her spot in the apartment. No new lease or contract was written for the change. There are unpaid fees for the vacant spot, and those fees are currently on my former roommate's account. The landlord has left it up to us to figure out how to handle payment. My former roommate wants to take this to small claims court, but I just want to pay and move on. What should I tell my landlord to best remove myself from this situation?
Attorney Answer
Because no new lease, addendum, or written agreement was signed when you moved into your roommate's old room, you are likely not personally obligated under the lease for the fees currently sitting on her account, and the clearest way forward is to get that distinction confirmed by your landlord in writing.
In general landlord-tenant law, whoever signs a lease is the one legally bound by its terms, including any fees tied to that unit or that tenant's obligations. When a tenant informally hands off their space to someone else, that arrangement does not automatically transfer legal responsibility to the new person unless the landlord agrees to a formal change, sometimes called a lease assignment, addendum, or a brand new lease. Since you mentioned no new contract was written, the fees currently on your former roommate's account most likely remain her legal responsibility toward the landlord, regardless of who is actually living in the room now.
That said, landlords sometimes try to hold whoever is currently occupying a space responsible in practice, even without formal paperwork, especially if you are also a signer on the original lease for the rest of the unit. It matters a lot here whether you were already a co-signer on the master lease before this happened.
What can help you the most right now:
1. Ask the landlord, in writing, to confirm exactly which named tenant is contractually responsible for the vacant spot fees under the current signed lease documents. 2. Do not verbally agree to "just handle it" between you and your former roommate in a way that could be read as you accepting her debt. Keep communications about payment in writing. 3. If the landlord wants you to formally take over that portion of the lease going forward, ask for a written addendum or new lease before paying anything tied to her account, so your future obligations are clear. 4. If you do decide to pay to keep the peace, get a written statement from your landlord and former roommate confirming that the payment settles the matter and does not admit ongoing liability.
Your former roommate's threat to go to small claims court is a separate dispute between the two of you and does not by itself change what the landlord can hold you responsible for under the lease.

Frequently Asked Questions
Am I responsible for my roommate's fees just because I am living in her old room?
Not automatically. Legal responsibility for a lease generally follows who signed it, not who is physically living there, unless a new agreement was signed adding you as responsible for that portion.
Should I pay the fees anyway to avoid a dispute?
You can choose to pay to resolve things quickly, but if you do, get written confirmation from your landlord and former roommate that the payment settles the matter, so it is not treated as an admission that you were legally responsible all along.
What if my landlord insists I am responsible even without a new contract?
Ask the landlord to point to the specific signed document that makes you responsible. If none exists, you can request a written addendum before agreeing to take on any new obligation, rather than assuming responsibility based on a verbal arrangement.
