R4538 - Acknowledged, proved or certified writing; conveyance of real property without the state.

Rule  4538.  Acknowledged,  proved or certified writing; conveyance of
  real property without the state. Certification of the acknowledgment  or
  proof  of  a writing, except a will, in the manner prescribed by law for
  taking and certifying the acknowledgment or proof  of  a  conveyance  of
  real  property  within  the  state  is  prima facie evidence that it was
  executed by the person who purported to do  so.  A  conveyance  of  real
  property,  situated  within  another state, territory or jurisdiction of
  the United States, which has been duly authenticated, according  to  the
  laws  of  that  state,  territory  or  jurisdiction, so as to be read in
  evidence in the courts thereof, is admissible in evidence in the state.
