Grant Deed Law and Legal Definition
A grant deed is a deed containing an implied warranty that there are no encumbrances on the property not described in the deed and that the person transfering the property actually owns the title. It must describe the property by legal description of boundaries and/or parcel numbers, be signed by all people transferring the property, and be acknowledged before a notary public. It is in contrast to a quit claim deed, which only conveys the interest that the transferor actually owns, if any, without a warranty of ownership.
A grant deed transfers the owner's ownership and promises that the title hasn't already been transferred to someone else or been encumbered, except as set out in the deed. This is the most commonly used kind of deed, in most states.
A warranty deed transfers ownership and explicitly promises the buyer that the grantor has good title to the property. It may make other promises as well, to address particular problems with the transaction.
