A more thorough explanation:

A full-covenant-and-warranty deed is a type of deed used to transfer ownership of real property from one person to another. It provides the highest level of protection for the buyer because the seller guarantees that they have clear title to the property and will defend the buyer against any claims made by others.

For example, if John sells his house to Jane using a full-covenant-and-warranty deed, John is guaranteeing that he has the legal right to sell the property and that there are no liens or other claims against it. If someone later comes forward with a claim to the property, John is responsible for defending Jane's ownership.

This type of deed is also known as a warranty deed and is commonly used in real estate transactions.
