§ 245. Estate which passes by grant or devise. A grant or devise of
real property passes all the estate or interest of the grantor or
testator unless the intent to pass a less estate or interest appears by
the express terms of such grant or devise or by necessary implication
therefrom. A greater estate or interest does not pass by any grant or
conveyance, than the grantor possessed or could lawfully convey, at the
time of the delivery of the deeds; except that every grant is conclusive
against the grantor and his heirs claiming from him by descent, and as
against a subsequent purchaser or incumbrancer from such grantor, or
from such heirs claiming as such, other than a subsequent purchaser or
incumbrancer in good faith and for a valuable consideration, who
acquires a superior title by a conveyance that has been first duly
recorded.
