@Bryce Davis, a quitclaim deed transfers any and all real estate rights in certain described real estate, but does not make any promises or warranties that the grantor actually owns anything at all.
It is frequently used to clear up possible title defects, or when someone makes a gift of land. Nobody wants to sign a regular warranty deed under those circumstances, later find out the title is defective, and then get sued.
At least in Alabama, there are two other types of deed in common usage.
A general warranty deed makes promises that the title is perfect and clean. If it is not, then the grantee can sue the grantor. Even if there is title insurance paid by the grantor, to protect the grantee, the grantor is not safe. That is because if there is a title defect, even if it arose before the grantor's period of ownership, the title insurance company will pay off, and then step into the shoes of the grantee and sue the grantor under its warranties. Usually the grantor goes a little crazy at that point and says to the title company, "It was your responsibility to FIND the title defects before we closed, and also, I was the one who PAID for the title insurance!!! It's not fair that you are suing me for your own mistakes!!!!!" The title company says, "Too bad, so sad..." and continues with their law suit and will ultimately win.
They tell the grantor, "Don't worry, now you can sue your own grantor under the title insurance you got when you bought the property." That is good advice, unless you inherited the property, or it was a gift, or the title company is out of business, or you bought it cheaply and quickly with no title insurance. Never be lulled into a false sense of security by a title company saying you should not worry about something because if they sue you, then you can sue somebody else. Plus, who wants to go through that grief and expense, anyway?
Another type of deed is a statutory warranty deed, also called a special warranty deed. This type makes promises that the grantor did not allow any title defects to arise during its period of ownership, but makes no promises about things that make have clouded the title from earlier. Same result with the title insurance company lawsuit as the general warranty deed, but the grantor knows if he allowed an IRS lien or placed a mortgage or something similar during his period of ownership. So, it is not unfair for it to get sued for its warranties. A warranty is a promise, by the way.
Bear in mind, this is all Alabama law. Tax sale investors should usually give only quitclaim deeds unless they have a Quiet Title court order. Nobody should ever give a general warranty deed, even with title insurance. There is just too much risk over things you have no way of knowing about.
Be careful about using quitclaim deeds found on the Internet or passed around among friends or colleagues. Something might say "Quitclaim Deed" at the top of the instrument, but contain words of warranty down in the body, using language nobody understands or pays attention to. The usual warranties are of seisin (possession), quiet enjoyment (freedom from interference from others, such as the lack of a boundary line dispute brewing, or condemnation proceedings in process, etc.) , right to convey (the right to sell the whole of the interest recited in the deed, and not just a partial owner, for example), freedom from encumbrances (no liens, undisclosed leases, or other claims) and defense of title as to all claims (a promise to sue other people to clear up the title if the warranties are broken).
Usually (but not always) the language with the warranties will be near the end of the deed, and will say something like, "And we do, for ourselves and for our heirs, executors, and administrators, covenant with the Grantees, and the Grantee's heirs and assigns, that we are lawfully seized in fee simple of said premises..."
