relief upon any equitable ground against any deed, instrument, or contract, or
against any right, title, or claim asserted by any plaintiff in the cause or
matter, or alleges any ground of equitable defence to any such claim of the
plaintiff, the court shall give to every equitable estate, right, or ground of
