What type of deed includes the covenant of seisin, stating the grantor's right to convey title?

The correct answer is a bargain and sale deed because this type of deed involves the grantor implicitly asserting that they hold title to the property and can convey it, thereby including the covenant of seisin. This covenant is a representation that the grantor owns the property and has the right to transfer it, even though the deed itself does not guarantee that the title is free of defects or encumbrances.

In contrast, a quitclaim deed does not provide any such covenant or guarantee regarding the ownership rights; it merely conveys whatever interest the grantor has, if any. A special warranty deed provides a limited warranty that covers only the period during which the grantor owned the property, and does not extend beyond that. Lastly, a general warranty deed offers comprehensive guarantees about the title against any claims, covering the entire history of the property, which also includes the covenant of seisin. However, the focus on the specific characteristics of a bargain and sale deed, particularly the assertion of the grantor's rights to convey title, makes it the most fitting choice in this context.
