Words usually found in a deed, showing the interest the grantee is receiving. A deed to "A, his heirs and assigns", would grant the property to A, with the right to assign said property or have it descend to A's heirs upon A's death. This would be considered a fee interest (estate). This would differ from, for example, a life estate granted to A, which would terminate upon A's death and could not be inherited by A's heirs.
