When the question is who owes it
Many deposit disputes are not about the condition of the apartment at all. They start when the building changes hands and the new owner says it never received the money, or when one roommate moves out while others remain on the lease. In New York, the deposit is held as the tenant's money rather than the landlord's, and a buyer of the building may become responsible for deposits paid to the prior owner, depending on the kind of building. Where several people signed one lease, the landlord usually returns the deposit when the whole tenancy ends, and dividing it among roommates is often a separate conversation. Commercial deposits are a different matter and mostly follow the lease itself.
The statement of deductions
For most residential tenancies, New York expects a landlord who keeps any part of a deposit to give the tenant an itemized statement within a set period after the tenant leaves. A landlord who misses that step can lose the right to keep any of the money, which is why the date the statement arrived, if it arrived at all, deserves attention. Ordinary wear from living in a home is generally not a proper deduction, while damage beyond that may be. Keep the envelope or email showing when the statement came, the move-out photos, proof of how you returned the keys, and the forwarding address you gave. If the landlord applied the deposit to rent, ask for the ledger showing how.
Choosing how to press the claim
Most tenants start with a written request that refers to the statement, or the lack of one, and asks for a specific amount. Small claims court is designed for disputes of this size and is often used without a lawyer, while larger amounts or claims bundled with other lease problems may belong in a different court. The state attorney general also takes complaints about deposits. For landlords, the same review works in reverse: we look at whether the paperwork supports what was kept before a dispute grows. Our initial review sorts out who holds the money now, what the timeline looks like, and whether the claim should be handled alone or folded into a wider dispute.
