Your roommate may the landlord to remove him from the lease. If you and your landlord agree to this change, then the roommate will no longer be responsible for any of the rent. This new agreement should be in writing and everyone should sign it to avoid later difficulties.
As a tip for next time, it is often a good idea to have a roommate agreement in place with all of the people you are living with. The agreement should specify:
- how rent will be paid
- how long each roommate remains responsible to pay their share of the rent
- what will happen to rent payments if a roommate leaves
