Issue: Whether or not the use of handwriting experts is necessary in order to prove the
authenticity of petitioner’s signature?
Held: No, they are necessary. The Court ruled that resort to handwriting experts is not
mandatory. Handwriting experts, while probably useful, are not indispensable in
examining or comparing handwritings or signatures. This is so since under Section 22,
Rule 132 of the Revised Rules on Evidence, the handwriting of a person may be proved
by any witness who believes it to be the handwriting of such person, because he has
seen the person write; or has seen writing purporting to be his upon which the witness
has acted or has been charged, and has thus acquired knowledge of the handwriting of
such person. Moreover, the opinion of a non-expert witness, for which proper basis is
given, may be received in evidence regarding the handwriting or signature of a person
with which he has sufficient familiarity.
The Legazpi City RTC was, therefore, not obliged to put a handwriting expert on the
witness stand and direct the latter to examine petitioner’s signatures in the foregoing
exhibits before ruling on their admissibility. It can, as it did, rely on the testimonies of the
prosecution witnesses who are familiar with petitioner’s handwriting/signature in
determining the admissibility of the aforesaid exhibits. It can, by itself, also compare
petitioner’s signature in the PDS with the petitioner’s signatures in the subject exhibits
with or without the aid of an expert witness and thereafter rule on the admissibility of
such exhibits based on its own observation. In short, it can exercise independent
judgment as regards the admissibility of said exhibits.
