A deed in which the grantor conveys title to the grantee and agrees to protect the grantee against title defects or claims asserted by the grantor and those persons whose right to assert a claim against the title arose during the period the grantor held title to the property. In a special warranty deed the grantor guarantees to the grantee that he has done nothing during the time he held title to the property which has, or which might in the future, impair the grantee’s title.
