It`s a good practice for a written lease to control the following details: There are a number of things you can include in a secure short-term rental agreement. Our model includes: if one of you wants to leave and tells the owner to terminate the contract, this can terminate the contract for all. If you are disabled, your landlord may need to change the lease if a contract term means you are worse off than someone without your disability. It is more difficult to prove what was agreed if it is not written. This is due to the fact that there is often no evidence of what has been agreed or that a particular problem has arisen that does not cover the agreement. You can also prove what has been agreed by other means, for example with emails or text messages. Some lawyers and real estate agents provide written rental templates. .
