Article 9 - (290 - 336) RECORDING INSTRUMENTS AFFECTING REAL PROPERTY
314 - Recording of conveyances acknowledged or proved without the state, when parties and certifying officer are dead.

§  314.  Recording  of  conveyances acknowledged or proved without the
  state, when parties and certifying officer are dead. When the  execution
  of  a  conveyance  of real property within this state is acknowledged or
  proved according to the laws of any other state of  the  United  States,
  and  a  certificate of the acknowledgment or proof signed by the officer
  taking it is annexed to or indorsed upon the instrument, if such officer
  and the grantor or mortgagor be dead and the death of  all  of  them  be
  proved by affidavit, sworn to in such state before an officer authorized
  by  its  laws  to  administer  an oath therein, the conveyance, with the
  affidavit or affidavits  annexed  thereto,  on  being  authenticated  as
  required  by  this  section, may be read in evidence and recorded in the
  same manner, and with like effect, as if the conveyance was acknowledged
  or proved and certified as required  by  the  laws  of  this  state.  To
  entitle  such  conveyance  and  affidavits  to  be  read in evidence, or
  recorded, a certificate of the clerk, recorder, register or prothonotary
  of the county in which the deceased officer resided, authenticating  his
  signature,  and  also  certifying that the conveyance is acknowledged or
  proved in all respects, as required by the laws of such state,  must  be
  annexed  to  the  original  certificate;  and a like certificate of such
  clerk, recorder, register or prothonotary, authenticating the  signature
  of  the  officer,  before  whom  the  affidavits proving the deaths were
  taken, must be annexed to  such  affidavits.  The  affidavits  on  being
  recorded,  are  presumptive evidence of the matters of fact, required to
  be stated therein.
