§36-4-7. Special covenant against encumbrances.
A covenant by a grantor in a deed, "that he has done no act
to encumber the said lands," or a covenant of like import, shall
have the same effect as if he had covenanted that he had not done
or executed, or knowingly suffered to be done or executed, any
act, deed or thing whereby the lands and premises conveyed or
intended so to be, or any part thereof, are, or will be, charged,
affected, or encumbered in title, estate or otherwise.
