A Warranty Deed is the transfer of real estate from one person to another, which warrants good and clear title to the real estate transferred. This means that the grantor (the person issuing the Warranty Deed) will defend and guarantee the worthiness of title to the grantee (the purchaser or person receiving the property) against any persons or entities making claims against the property.  In many states, a Warranty Deed often includes some or all of the following covenants: seisin, quiet enjoyment, right to convey, freedom from encumbrances, and defense of title against all claims.

In a Quit Claim Deed, the grantor transfers to the grantee all the right, claim, or interest in the real estate that the grantor possesses. It does not contain any of the covenants or warranties found in a Warranty Deed. It does not covenant or warrant that the grantor's interest in the real estate is valid, but simply transfers any interest, claimed by the grantor, to the grantee.

A Warranty Deed provides a buyer of real estate property far more protection than a Quit Claim Deed.
