Adeed where the grantor warrants against (and agrees to defend against) title defects and encumbrances that arose after she acquired the property is called:

The answer is a special warranty deed. It is a real estate deed by which the seller only permits or guarantees the title against imperfections in clear title that may have risen during the period of its contract or ownership of the property. The grantor of a special warranty deed does not offer a warranty or guarantee against any defects in clear title that was prior to its ownership. A special warranty deed is an exemption to the more commonly issued general warranty deed. A special warranty deed is really of lower quality, proposing less security or protection against possible defects in clear title than a general warranty deed.
