21 GCA § 4210: Implied Covenants.

From the use of the word grant in any conveyance by which an estate of inheritance or fee simple is to be passed, the following covenants, and none other, on the part of the grantor for himself and his heir to the grantee, his heirs, and assigns, are implied, unless restrained by express terms contained in such conveyance:

1. That previous to the time of the execution of such conveyance, the grantor has not conveyed the same estate, or any right, title, or interest therein, to any person other than the grantee.

2. that such estate is at the time of the execution of conveyance free from encumbrance done, made, or suffered by the grantor, or any person claiming under him.

Such covenants may be sued upon in the same manner as if they had been expressly inserted in the conveyance.
