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

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.
