I have a 'Warranty Deed' that granted me the property my mom lived in, conveyed in 1975. However, in it, it reminds me of a 'Beneficiary Deed' the way it is written. In 2003, my mom conveyed the same property to my sister under a 'Beneficiary Deed'. There is no 'Revocation Deed' made to revoke the first 'Warranty Deed'. Who should have the rights to the property?
