You can also prove what has been agreed by other means, for example with emails or text messages. The lease may be held in trust until the young person is 18 years of age. A co-signer is typical in situations where the tenant does not have a rental history or has no credit history (often among university students). The co-signer is legally required to pay by the tenant for unpaid rent or damage. If you are still not sure what type of rental you have, you can use the controller for Shelter`s rental right. The lease you have depends on the facts of your situation, not what your agreement says. For example, if you pay rent to a private landlord who does not reside in your home and you have agreed to a 6-month lease agreement, you will likely have a secure short construction contract (or an insured rental agreement in Scotland). This is the case even if your agreement says something else. Check the type of rental you have. In England and Wales, most tenants do not have legal protection on a written lease..
