While the deed without warranty sells and conveys the property to the buyer, it's only slightly better than a quitclaim deed. A quitclaim deed conveys whatever interest the Grantor has in the property, if there really is any interest, and may not be a deed with any effect at all.A quitclaim deed transfers a person's interest in a property to another without warranties. A warranty deed and a quit claim deed are both legal documents that can be used to transfer ownership of real property. Q: What are the requirements to upgrade a quitclaim deed to a warranty deed? A quitclaim deed is a legal document that transfers ownership of real property from one party to another. Like the Warranty Deed, a Deed Without Warranty uses the "grant, sell and convey" language to establish title in the buyer. It is important to note that a Quitclaim Deed should never be used to transfer house title in Texas. A Quitclaim does not TRANSFER TITLE.
