§ 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.
