Tenants in Common with her Brother

[Unregistered]

Mrs. A was a tenant in common with her brother. Mrs. A. transfered her portion of the property in a quitclaim deed to her daughter and son in law. The brother now claims that he had a signed agreement with Mrs. A. The agreement was never witnessed, notorized, or attached to the deed. The deed lists us a co-owners of the property. The agreement lists that he has exclusive use of the attic area. Mrs. A says the paper she signed gave her brother use of the attic area until she needed it. How valid is that peice of paper? Also, the agreement says for the life of the agreement.....what does that mean?
Anxious to know what to do.

He could try to sue Mrs A for damages but normally your deed would be valid as to you and you need not accept his claims.
