A West Virginia roommate agreement is a written rental contract between a group of people who are intent on creating a harmonious living environment in a shared rental property. While the agreement is not attached to the original lease, it is legally binding and must not conflict or interfere with the provisions of the lease in any way.

The roommate agreement is particularly useful in situations where one or more roommates are not on the lease as it prevents an unfair distribution of financial liability. In addition to rent, deposits, and other fees associated with the property, this agreement allows the roommates to decide on a number of other aspects of their living arrangement, such as chores, duties, pets, guests, common areas, parking, and quiet times.
