What do you call the historical instruments that convey ownership of a property to a new person?

The correct answer is the title deed. A title deed is a legal document that serves as evidence of ownership of a specific piece of property. It outlines the rights and interests that the owner has in the property and is essential for transferring ownership from one party to another during a sale or conveyance. The title deed typically includes important details such as the property description, the names of the buyer and seller, and any conditions of the sale.

In contrast, mesne conveyance refers to any intermediate transfer of property between the original owner and the final recipient, rather than the final instrument that conveys ownership. A bill of sale is primarily used for transferring ownership of personal property, such as vehicles or furniture, not real estate. A lease agreement is a contract that outlines the terms under which one party agrees to rent property owned by another party, and it does not convey ownership but rather grants temporary possession.
