Warranty deeds are used to convey title to real property and provide promises or guarantees from the seller the he or she is the owner of the property, has a right to convey the property, and that the property is free and clear of liens and other types of encumbrances on the property. This warranty deed is used when the transfer is to one person or to tenants in common. “Tenants in common" is a form of co-ownership by which each owner holds an undivided interest in real property as if he or she was the sole owner. If one co-tenant dies, his or her interest in the real property passes to his or her heirs (not to the other co-tenant).
