Two of the most common types of deeds are the warranty deed and the quitclaim deed. Unlike a general warranty deed, an Illinois quitclaim deed does not assure a free and clear title.A warranty deed promises the seller that he or she legally owns the property. A warranty deed provides guarantees of clear title to real property and that the current owner has the legal right to sell it or transfer it to another party. No Warranty: Unlike warranty deeds, quit claim deeds do not provide any guarantee about the property's title status. A quitclaim deed is also called a nonwarranty deed and is the least safe form of title transfer, while a warranty deed is the safest. Quit claim deeds operates, in effect, as a release of whatever interest the grantor has or may have in the property. This is because a quitclaim deed only changes who owns the title to the property, but not the mortgage itself. An Illinois Quitclaim Deed conveys whatever ownership the Grantor has in the property to the Grantee without any warranties. Instead, quitclaim deeds are used when there is a property transfer outside of a real estate sale.
