In Santos v. Local Civil Registrar of Manila (G.R. No. 265114, February 3, 2026), a woman applied for a CENOMAR to marry her fiancé and discovered she was already recorded as married to a Japanese national she said she had never met. Her Rule 108 petition to cancel the “wife portion” of that marriage certificate was denied — all the way up. A marriage certificate is a public document carrying a presumption of regularity, so forgery is never presumed and must be shown by clear and convincing evidence. Her own denial, her mother, a co-worker and a neighbour were not enough.
This case applies Rule 108 of the Rules of Court, which governs cancellation and correction of civil registry entries. Read the rule on who must be made a party: Rule 108, Section 3 — Parties, with annotation and interpreting cases.
What the Court Actually Held
Lizza C. Santos went to secure a Certificate of No Marriage so she could marry her fiancé. Instead she was told a marriage already existed: a certificate on file with the Manila Local Civil Registrar recording that she married Yoshio Imai, a Japanese citizen, at 10:00 a.m. on August 7, 2010 at Manila City Hall, before a named solemnising officer. The certificate carried what appeared to be her signature, certifying that she had personally appeared.
She filed a petition in the Regional Trial Court to cancel the entire wife portion, the place and date of marriage, and her name and signature. Her case was that she had never met Imai and that her signature had been forged. On the day in question, she said, she was at work in Sta. Maria, Bulacan.
She supported this with her own testimony, her mother (who said she had never been asked about a marriage), a co-worker who placed her at their Bulacan workplace from 6:00 a.m. to 6:00 p.m., and a neighbour who saw her leaving in her uniform at 5:30 a.m. and cooking dinner at 7:00 p.m. The Office of the Solicitor General, through the City Prosecutor, appeared but presented no evidence of its own.
She lost at every level. In a decision penned by Senior Associate Justice Marvic M.V.F. Leonen, the Supreme Court’s Second Division denied the petition and affirmed the Court of Appeals.
The reasoning starts with the status of the document. A marriage certificate is an official record in the custody of the civil registrar; it is a public document, it enjoys a presumption of regularity and authenticity, and its entries are prima facie evidence of the facts stated. To overturn it as a forgery therefore requires clear, positive and convincing evidence — a standard the Court, quoting Tankeh v. Development Bank of the Philippines, described as less than proof beyond reasonable doubt but greater than mere preponderance.
That distinction decided the case. Santos argued in her own pleadings that she had proved by preponderance of evidence that she did not marry Imai. The Court took her at her word: by her own account she had shown only a probability, which is a lower standard than the one the law requires.
Several specific gaps compounded the problem. She never obtained an NBI examination, because she had submitted only a photocopy of the certificate — which the NBI told her did not reflect the writing strokes — and specimen signatures it found unsuitable for comparison. She produced no daily time record for August 7, 2010, so her alibi rested entirely on recollection. Her Bulacan workplace was close enough to Manila City Hall that being at one did not make the other impossible. And she never explained how a stranger’s certificate came to contain all of her correct personal details except her address.
The Court was careful on one point that is widely misunderstood: expert testimony is not strictly required. A judge may find forgery without a handwriting expert. But something independent is required, and Santos offered nothing beyond her own denial and witnesses to her whereabouts.
What Changed, and What Didn’t
No rule was rewritten. The value of this decision is that it shows, against a real record, exactly where these petitions fail — and it does so by contrast with Republic v. Olaybar, the case petitioners in this situation usually cite because there the cancellation was granted.
The Court spelled out why Olaybar succeeded. That petitioner produced an employee of the court where the marriage was supposedly celebrated, who testified that the ceremony did happen but that the woman who appeared was definitely not her. She produced a document examiner who testified the signature was forged. And she gave a coherent account of how her identity had been used — she had handed her personal details to a travel agency operator to obtain a passport. She also impleaded the alleged husband.
Santos had none of that. She did not implead Imai at all. On that point the Court restated the procedural rule: where the correction sought is not merely clerical but affects civil status, Rule 108 requires a genuinely adversarial proceeding in which both the civil registrar and the supposed spouse are impleaded.
The Court also repeated Olaybar’s warning, which matters for anyone tempted to use this route as a shortcut: a Rule 108 petition is not a substitute for a direct action to question the validity of a marriage. You cannot dissolve a marriage by editing the register.
Who This Affects
This is a more common problem than people assume. Identity details are handed over routinely — for passports, for job applications, for agency processing — and every so often someone discovers, usually when applying for a CENOMAR before their real wedding, that a marriage already sits on their record. The practical consequence is severe: they cannot marry, and their civil status is wrong on every document that draws from the PSA.
For them, Santos is a warning rather than a door closing. The remedy exists and Olaybar shows it can succeed. But it succeeds on independent, documentary and third-party proof — not on sincerity. The person who discovers a false marriage record should be building a file from day one, not simply preparing to testify.
It also affects anyone advising on timing. Santos said she discovered the record in 2015 and the case was only finally resolved in 2026. Evidence decays: workplaces close, records are purged, witnesses move. The strength of a petition filed promptly is not the same as one filed years later.
What It Means in Practice
- Get a certified true copy of the marriage certificate from the civil registrar, not a photocopy. The NBI refused to examine Santos’s photocopy, and that single failure hollowed out her case.
- Submit proper specimen signatures. The NBI also rejected hers as unsuitable for comparison — ask what they require before submitting.
- An expert is not legally required, but bring one anyway. In Olaybar a document examiner testified; in Santos nobody did, and that is the clearest difference between the two outcomes.
- Implead the supposed spouse. A substantial Rule 108 correction needs an adversarial proceeding with both the civil registrar and the alleged spouse as parties.
- Prove the alibi with documents, not memory — daily time records, payroll, logbooks, CCTV. And be ready to show it was physically impossible to attend, not merely unlikely.
- Explain how your details got there. An unexplained certificate carrying all of your correct information is evidence against you, and the Court said so.
- Understand what the remedy is for. Rule 108 corrects a record. It does not dissolve a marriage — if a marriage genuinely took place, the action is a different one entirely.
