Annulment in the Philippines: Both Spouses Wanting Out Is Not Collusion

The Supreme Court just narrowed a rule that has been sinking petitions for years — and clarified what collusion actually means.

News hook: On July 2, 2026, the Supreme Court announced its decision in Republic v. Wong (G.R. No. 276986, promulgated February 3, 2026), written by Associate Justice Maria Filomena D. Singh for the Third Division. Spouses' mutual desire to end their marriage, standing alone, is not enough to prove collusion — and neither is the respondent spouse's failure to file an answer or oppose the petition.

Legal question

What counts as "collusion" in a Philippine annulment or nullity case, and can a court dismiss the petition simply because both spouses want the marriage to end, or because the respondent did not contest it?

Applicable laws and rules

Why this matters

The Philippines has no general divorce law. For most Filipinos, a court declaration that the marriage is void (nullity) or voidable (annulment) is the only lawful way out of a marriage — which makes every procedural obstacle in those cases enormously consequential. "Collusion" is one of the biggest. Because the law requires the State to guard against spouses conspiring to fake a ground, some trial courts have treated the ordinary reality that both spouses want out — or that the respondent simply did not show up to fight — as if it were evidence of a scheme. The Supreme Court has now said that is wrong.

First, the distinctions that trip everyone up

People use "annulment" as a catch-all, but Philippine law draws sharp lines, and choosing the wrong remedy can waste years.

Declaration of absolute nullity applies to a marriage that was void from the beginning — it never legally existed. Grounds include psychological incapacity (Article 36), absence of a valid marriage license, bigamy, and incest. A void marriage never becomes valid with the passage of time, so there is no prescriptive period.

Annulment applies to a voidable marriage — valid when celebrated, but capable of being set aside for a defect existing at the time. Article 45 lists them: lack of parental consent for a party aged 18 to below 21, unsound mind, fraud, force or intimidation or undue influence, physical incapacity to consummate, and a serious and incurable sexually transmissible disease. A voidable marriage is fully valid until a court annuls it, and Article 47 sets prescriptive periods — so these grounds can expire.

Legal separation does not dissolve the marriage at all. The spouses live apart and property is divided, but the marriage bond remains and neither spouse may remarry.

Divorce is not generally available. As of this writing there is still no absolute divorce law: the House of Representatives passed the Absolute Divorce Act (House Bill 9349) on third reading, but the Senate has not passed it, so it is not law. Two narrow exceptions exist — divorce under the Code of Muslim Personal Laws (P.D. No. 1083) for Muslim Filipinos, and judicial recognition of a valid foreign divorce under Article 26(2) where a foreign spouse is involved.

What the Supreme Court decided in Republic v. Wong

The wife petitioned to declare the marriage void, alleging her husband could not fulfill his marital duties because of continued physical, psychological, and economic abuse that began even before the marriage. The husband did not file an answer. As Article 48 requires, the Regional Trial Court ordered the Provincial Prosecutor to investigate possible collusion. The prosecutor investigated and reported that there was no collusion.

At trial the wife presented several witnesses, including a clinical psychologist and the husband's own father and cousin, who testified about his vices and abusive behavior. The husband presented no witnesses and did not oppose the petition. The RTC dismissed the case anyway — holding the evidence insufficient to prove psychological incapacity, and distrusting the husband's relatives, noting the father admitted discussing his testimony with his son and that the husband seemed willing to have the marriage ended. The Court of Appeals reversed. The Republic, through the Office of the Solicitor General, went to the Supreme Court arguing the spouses had colluded.

The Supreme Court disagreed and affirmed the nullity. Citing De Ocampo v. Florenciano, it defined collusion as a secret agreement in which spouses cooperate to make it appear that one of them committed, faked, or concealed a marital offense in order to obtain the dissolution. Applying that definition, the Court held:

The Court closed with an unusually direct statement of principle:

"Marriage, in its truest form, must be a sanctuary: a space of mutual respect, care, and emotional safety. It must never become a chain that binds a person to a relationship that is not only fundamentally flawed, but damaging. While the ideal remains that individuals choose wisely in love and commitment, the reality is that human beings make mistakes. When a marriage has become irreparably broken, the spouses so deeply incompatible as to render its continued existence unjust, the Court should not stand in the way."

How psychological incapacity is proven after Tan-Andal

Because Article 36 is the most common route to nullity, the standard for proving it matters as much as the collusion rule. In Tan-Andal v. Andal (G.R. No. 196359, May 11, 2021), the Supreme Court En Banc substantially reframed it. Psychological incapacity is a legal concept, not a medical one. It need not be a mental disorder recognized by the scientific community, and it need not be shown to be medically permanent and incurable. As a result, expert testimony from a psychologist or psychiatrist is no longer mandatory in every case — the Court abandoned the earlier Molina requirement that the root cause be medically or clinically identified and proven by experts. What must be proven is the durable, enduring aspect of a person's personality — the "personality structure" — manifesting through clear acts of dysfunctionality that undermine the family. Ordinary witnesses who knew the spouse before the marriage may testify to those behaviors. The standard of proof is clear and convincing evidence, higher than the preponderance of evidence used in ordinary civil cases, because the law presumes marriages are valid.

What individuals should know

The most practical takeaway from Wong is that an uncontested petition is not automatically a doomed petition. If your spouse does not fight the case, that is not collusion, and a court should not dismiss on that basis alone. Neither is the fact that you both want the marriage to end.

But do not over-read the ruling. The State still participates in every nullity and annulment case: under Article 48 the court must order a prosecutor to appear for the State, to prevent collusion and to ensure evidence is not fabricated or suppressed. Article 48 also provides that no judgment may be based on a stipulation of facts or a confession of judgment — meaning you and your spouse cannot simply agree in writing that the marriage is void and have a court rubber-stamp it. You must still prove your ground with evidence, to the clear-and-convincing standard. Real collusion — coaching a spouse to fake a ground, fabricating evidence, agreeing to suppress a genuine defense — remains fatal, and is exactly what the prosecutor is there to catch.

Finally, be realistic about the process. These are court cases that typically take years and are not cheap, they are filed with the Family Court covering your residence, and the outcome turns on the quality of your evidence rather than on both parties simply wanting it. If you are experiencing abuse, the abuse itself may give rise to separate and much faster remedies — including protection orders under the Anti-Violence Against Women and Their Children Act — which do not require you to wait for a nullity case to conclude.
