Final answer:
The deed guarantee in question is an example of a covenant of warranty forever, ensuring protection against future title claims and compensation for losses due to title failure.
Step-by-step explanation:
The deed contains a guarantee that the grantor will compensate the grantee for any loss resulting from the title's failure in the future. This is an example of a covenant of warranty forever, also known simply as warranty forever. This type of covenant assures the grantee that the grantor will protect and defend the title against all claims and will compensate the grantee for any loss incurred due to a defective title. It is one of the six traditional covenants for title that can be included in a deed.
