Before drafting your roommate agreement, it is important for both of you to understand the difference between a lease and a roommate contract. A lease contract is an agreement between the landlord and the tenants, while the roommate agreement is a legal document that binds the individual tenants who agree on several terms of living with each other. Moreover, the lease agreement does not decide the behavior of the roommates towards each other. Since the behavior of the tenants does not violate the law, roommates are free to do anything. In addition to that, it is likely that your roommate can leave the apartment and never return, leaving you to pay the rent. How often can you borrow things? What kinds of things can’t be borrowed? This sample template includes all that and the specific details of how to live harmoniously. The Parties shall abide by the terms of the lease at all times, which is attached hereto as Exhibit A (the “Lease”). Should either Party breach the Lease, the breaching Party shall be liable to the non-breaching Party for any costs incurred curing the breach or other resulting costs.
