I have a cousin trying to get me to sign documents and I just want to make sure im not giving up my rights to the inherited property

I need to know what this means "to have and to hold the property, together with all and singular in the rights and appurtenances belonging in any way to the property subject to the provisions stated above, to Grantee, his heirs, personal representatives, successors and assigns to warrant and forever defend all and singular the property to Grantee and his heirs, personal representatives, successors, and assigns against every person lawfully claiming or to claim all or any part of the property subject to the provisions stated above, by through or under grantors but not otherwise." I want to make sure I am not signing away my rights here.
