A Delaware roommate agreement is a contract supplemental to a residential lease agreement that relays the rules of a shared dwelling between a group of individuals. Unlike a lease, the roommate agreement does not involve the landlord and will usually contain certain terms that are not legally enforceable (cleaning duties, food sharing, common areas, etc.).
The purpose of the document is to establish rules and responsibilities that contribute to a harmonious living arrangement with as few disputes as possible. Having all parties sign the document legally binds them to uphold responsibilities such as paying their portion of rent and utilities, giving proper notice before moving out, and restricting unauthorized occupants.
