Not too long ago, we were called to pass upon the issue of the probative value of a marriage contract issued by the church to prove the fact of marriage.1 Once again, it behooves upon us to determine whether the marriage contract or Contrato Matrimonial, as it is denominated in this case, is sufficient to prove the fact of marriage.

The Court of Appeals correctly ruled that it is a private document. As early as in the case of U.S. v. Evangelista,22 it has been settled that church registries of births, marriages, and deaths made subsequent to the promulgation of General Orders No. 6823 and the passage of Act No. 190 are no longer public writings, nor are they kept by duly authorized public officials. They are private writings and their authenticity must therefore be proved as are all other private writings in accordance with the rules of evidence.24

Under Section 20, Rule 132, Rules of Court,25 before a private document is admitted in evidence, it must be authenticated either by the person who executed it, the person before whom its execution was acknowledged, any person who was present and saw it executed, or who after its execution, saw it and recognized the signatures, or the person to whom the parties to the instruments had previously confessed execution thereof.26 As observed by the Court of Appeals, petitioners failed to present any one of such witnesses. In fact, only Simplicia testified that her mother gave her the marriage contract. Unfortunately however, she was not present during its execution nor could she identify Benita’s handwriting because Simplicia admitted that she is illiterate.

Petitioners insist on the admissibility of the marriage contract on the ground that it is a duplicate original, hence, the original need not be produced. We do not agree. We had previously ruled in Vallarta v. Court of Appeals27 that " a signed carbon copy or duplicate of a document executed at the same time as the original is known as a duplicate original and maybe introduced in evidence without accounting for the non- production of the original. But, an unsigned and uncertified document purporting to be a carbon copy is not competent evidence. It is because there is no public officer acknowledging the accuracy of the copy."28

Next, while petitioners concede that the marriage contract is a private document, they now argue that it is an ancient document which need not be authenticated. Petitioners’ argument still has no merit. Section 21, Rule 132 defines an ancient document as one that: 1) is more than 30 years old; 2) is produced from custody in which it would naturally be found if genuine; and 3) is unblemished by any alteration or by any circumstance of suspicion. The marriage contract was executed on 9 October 1929, hence it is clearly more than 30-years old. On its face, there appears to be no evidence of alteration.

The marriage contract however does not meet the second requirement.

Ancient documents are considered from proper custody if they come from a place from which they might reasonably be expected to be found. Custody is proper if it is proved to have had a legitimate origin or if the circumstances of the particular case are such as to render such an origin probable. If a document is found where it would not properly and naturally be, its absence from the proper place must be satisfactorily accounted for.29

Gibson v. Poor30 cited the reason why it is required that an ancient document shall be produced from the proper depository:

x x x that thereby credit is given to its genuineness. Were it not for its antiquity, and the presumption that consequently arises that evidence of its execution cannot be obtained, it would have to be proved. It is not that any one particular place of deposit can have more virtue in it than another, or make that true which is false; but the fact of its coming from the natural and proper place, tends to remove presumptions of fraud, and strengthens the belief in its genuineness. It may be false, and so shown, notwithstanding the presumptions in its favor. If found where it would not properly and naturally be, its absence from the proper place must be satisfactorily accounted for; but that being done and all suspicions against its genuineness removed, we can discover no reason why it may not be read in evidence. The real question which is to affect its consideration is, whether the instrument offered is genuine, and contains a true statement of what it purports to. In the Bishop of Meath v. Marquis of Winchester, 2 Bing. 183, Tindal, C. J., speaking of ancient documents, holds this language. "It is not necessary that they should be found in the best and most proper place of deposit. If documents continued in such custody, there never would be any question as to their authenticity; but it is when documents are found in other than their proper place of deposit, that the investigation commences whether it was reasonable and natural under the circumstances in the particular case, to expect that they should have been in the place where they are actually found; for it is obvious, that while there can be only one place of deposit strictly and absolutely proper, there may be many and various that are reasonable and probable, though differing in degree; some being more so, some less; and in those cases the proposition to be determined is, whether the actual custody is so reasonably and probably accounted for, that it impresses the mind with the conviction, that the instrument found in such custody must be genuine." Some authorities hold, that the antiquity of the document is alone sufficient to entitle it to be read, and that the other circumstances only go to its effect in evidence.
