Final answer:
The term for a deed that only warrants that the grantor has not caused a defect in title during their period of ownership is a Special Warranty Deed.
Step-by-step explanation:
The term for a deed that warrants only that the grantor has done nothing to cause a defect in title is a Special Warranty Deed. Unlike a General Warranty Deed, which guarantees the title against defects arising at any point in time, even before the grantor owned the property, the Special Warranty Deed only covers the period during which the grantor held title. In contrast, a Quitclaim Deed offers no warranties whatsoever, simply transferring any interest the grantor may have without any promise about title quality. An Executor's Deed is used by an executor of an estate to transfer property owned by the decedent.
