What type of deed provides the most legal promises, covenants, and warranties to the buyer?

A Full Covenant and Warranty Deed is indeed the type of deed that offers the most legal promises, covenants, and warranties to the buyer. This kind of deed guarantees that the seller has a clear title to the property and full ownership rights, meaning that no one else can claim an interest or right to the property.

In addition, it provides specific covenants, including the covenant of seisin (the grantor's promise they own the property), the covenant against encumbrances (the promise that there are no undisclosed liens or encumbrances on the property), and the covenant of quiet enjoyment (the guarantee that the grantee will not be disturbed in their ownership). These extensive assurances protect the buyer and offer significant legal recourse if any issues arise concerning ownership or title defects.

In contrast, other types of deeds such as a Quitclaim Deed transfer only whatever interest the grantor has without any guarantees or warranties regarding the title, a Special Warranty Deed offers limited protection typically covering only the period during which the seller owned the property, and a Bargain and Sale Deed implies a transfer of interest but provides minimal protection, usually missing the detailed warranties that a Full Covenant and Warranty Deed includes.
