What happens to the deposit when a roommate moves out

A security deposit is held against the tenancy, not against the people in it, so it is normally returned once — after everybody has gone, to whoever is still on the lease at the end. Somebody leaving in month seven is not owed anything by the landlord that month. They are owed something by the household, and the only question worth settling in advance is what.

The two ways households handle it

The first is that the person moving out is bought out by whoever replaces them. The incoming roommate pays their share of the original deposit directly to the person leaving, and the amount held by the landlord never changes. It is tidy, it needs no money from anyone still living there, and it only works if there is a replacement.

The second is that the remaining household pays the leaver out and absorbs their share. That is cleaner emotionally and harder financially, because it asks the people staying to find real money for something they will not get back until the end of the tenancy.

Damage is not split the same way as the deposit

When the itemised statement finally arrives, most households find it separates into two piles. Damage inside one bedroom belongs to whoever slept in it. Cleaning, common-area damage and any unpaid rent belong to everybody, usually in the same proportions as the rent.

Agreeing that division while everybody is still on speaking terms is the whole trick. It is an abstract conversation in September and a very concrete one in June.

Take photographs of the room, not the flat

The dispute that actually happens is never about the state of the kitchen. It is about one bedroom, months later, with nobody able to say what it looked like when that person arrived. A dozen photographs on the day somebody moves in costs nothing and settles it.

Deposit rules differ by state and by country, and some places require the money to be held in a specific scheme with its own dispute process. This is what households tend to agree between themselves; it is not legal advice and it does not override your lease.

💡Whatever you agree, write it in a message rather than saying it in a kitchen. The version that exists in two memories is the version that stops matching.
