In the Philippines, marriage is a special contract of permanent union between a man and a woman entered into in accordance with law for the establishment of conjugal and family life. It is governed exclusively by the Family Code of the Philippines (Executive Order No. 209, series of 1987, as amended). While the great majority of marriages are publicly solemnized and registered with the local civil registrar, unregistered and secret marriages occasionally occur. These unions raise distinct legal issues when one or both parties seek to dissolve them through annulment or declaration of nullity. This article examines the legal framework, the distinction between valid, voidable, and void marriages, the specific challenges posed by unregistered or secret marriages, the applicable grounds, and the complete procedural steps required under Philippine law.

Definition and Legal Status of Unregistered and Secret Marriages

An unregistered marriage is one that has been duly solemnized before an authorized person but has not been recorded in the civil registry as mandated by Article 22 of the Family Code. A secret marriage, by contrast, is generally understood as a ceremony performed privately, without public notice, publicity, or the knowledge of relatives and friends. It may or may not involve registration.

The Family Code is clear that registration is not an essential or formal requisite for the validity of marriage. It serves merely as the best evidence of the fact of marriage and protects third persons. A marriage that satisfies the essential and formal requisites remains valid even if unregistered. Conversely, if any essential or formal requisite is absent, the marriage is void from the beginning, regardless of registration.

Essential and Formal Requisites of Marriage

Article 2 of the Family Code enumerates the essential requisites: (1) Legal capacity of the contracting parties, who must be a male and a female; and (2) Consent freely given in the presence of the solemnizing officer.

Article 3 lists the formal requisites: (1) Authority of the solemnizing officer; (2) A valid marriage license, except in the cases provided in Chapter 2 of Title I (marriages in articulo mortis, remote places, and marriages after five years of cohabitation under Article 34); and (3) A marriage ceremony which takes place with the appearance of the contracting parties before the solemnizing officer and their personal declaration that they take each other as husband and wife in the presence of not less than two witnesses of legal age.

Article 4 declares that the absence of any essential or formal requisite renders the marriage void ab initio, except as otherwise provided. Article 5 further requires that the contracting parties must be at least eighteen years of age and must not be subject to any legal impediments.

Void Marriages versus Voidable Marriages

Philippine law distinguishes sharply between void marriages (which are inexistent from the beginning) and voidable marriages (which are valid until annulled by a competent court).

Void marriages (Declaration of Absolute Nullity) include those enumerated in Articles 35, 36, 37, 38, and 41 of the Family Code, among others. Common examples relevant to unregistered or secret marriages are:

Marriages solemnized without a valid license and without qualifying for any exemption (Article 35[2]);
Marriages where one party was psychologically incapacitated to comply with the essential marital obligations (Article 36);
Incestuous marriages (Article 37);
Marriages against public policy (Article 38); and
Subsequent marriages contracted before the finality of a prior judgment of nullity or annulment (bigamous or polygamous marriages under Article 41, subject to the rule on presumptive death).

Voidable marriages (Annulment) are governed by Article 45 and include:

Lack of parental consent for parties aged 18 to below 21;
Unsound mind;
Fraud (concealment of a previous conviction, pregnancy by another, sexually transmitted disease, or homosexuality);
Force, intimidation, or undue influence;
Physical incapacity to consummate the marriage (impotence); and
Serious and incurable sexually transmitted disease.

A secret or unregistered marriage may fall under either category. If it lacked a license and no exemption applied, it is void and subject to a petition for declaration of absolute nullity. If all requisites were present but a ground for annulment exists, the marriage is voidable and may be annulled.

Special Challenges in Proving Unregistered or Secret Marriages

The primary obstacle in cases involving unregistered or secret marriages is proving that the marriage actually took place. Because no marriage certificate exists in the civil registry, the petitioner must rely on secondary evidence under the Rules of Court (Rule 130). Acceptable proofs include:

Testimony of the solemnizing officer;
Affidavits or testimony of the two witnesses required by Article 3(3);
Photographs, video recordings, or invitations (if any);
Joint bank accounts, insurance policies, or other documents showing the parties held themselves out as husband and wife;
Birth certificates of children born to the union; and
Affidavits of persons who knew of the marriage.

Once the existence of the marriage is established by preponderance of evidence, the court may proceed to determine its validity or voidability.

Grounds Most Commonly Invoked

The most frequently used ground in Philippine annulment and nullity cases, including those involving secret or unregistered marriages, is psychological incapacity under Article 36. This ground requires proof that a party is psychologically incapacitated to fulfill the essential obligations of marriage—mutual love, respect, support, and fidelity—at the time of the celebration of the marriage. The incapacity must be grave, juridically antecedent, and incurable. Expert testimony from a psychiatrist or psychologist is almost always required, though the Supreme Court has clarified in landmark decisions that the totality of evidence, including the parties’ behavior during marriage, may suffice.

Other grounds remain available depending on the facts of each case.

Procedural Steps for Annulment or Declaration of Nullity

The process is governed by the Family Code and the Rule on Declaration of Absolute Nullity of Void Marriages and Annulment of Voidable Marriages (A.M. No. 02-11-10-SC, as amended). Jurisdiction lies with the Regional Trial Court (Family Court) of the place where the petitioner or respondent has resided for at least six months prior to the filing of the petition.

The complete step-by-step process is as follows:

Pre-Filing Consultation and Preparation
The petitioner consults a lawyer experienced in family law. All available evidence of the marriage’s existence and of the ground(s) for nullity or annulment is gathered. A verified petition is prepared containing the facts, the ground(s), and the reliefs prayed for (declaration of nullity/annulment, custody and support of children, if any, and liquidation of properties).
Filing of the Petition
The petition is filed with the appropriate Family Court. The docket fee is paid. If the petitioner is indigent, an affidavit of indigency may be filed to seek exemption from fees.
Service of Summons and Answer
The respondent is served with the summons and a copy of the petition. The respondent has fifteen (15) days (or thirty [30] days if outside the Philippines) to file an answer. If the respondent fails to answer, the court may proceed with the case but must still require the public prosecutor to investigate for collusion.
Public Prosecutor’s Participation
The Office of the Solicitor General or the city/provincial prosecutor is furnished a copy of the petition and participates to ensure that no collusion exists between the parties and that evidence is not fabricated.
Pre-Trial and Mediation
A pre-trial conference is held. The court may refer the parties to mediation. If the ground is psychological incapacity, the court may order a social worker’s report or further psychological evaluation.
Trial Proper
The petitioner presents evidence first. Witnesses, including the petitioner, the solemnizing officer, marriage witnesses, and experts, testify. Documentary evidence is marked and offered. The respondent may present counter-evidence. The public prosecutor cross-examines.
Decision
The court renders a decision declaring the marriage void ab initio or annulling the voidable marriage. The decision becomes final only after the reglementary period for appeal has lapsed or after any appeal is resolved.
Registration of the Decree
Upon finality, the decree of nullity or annulment is registered with the local civil registrar where the marriage was recorded (or where it should have been recorded in the case of unregistered marriages) and with the Philippine Statistics Authority. Only after registration can the parties remarry.

Effects of the Judgment

A decree of annulment or nullity restores the parties to their status before the marriage. Under Article 50 of the Family Code, the effects include:

Dissolution of the absolute community or conjugal partnership;
Liquidation, partition, and distribution of properties;
Delivery of presumptive legitime to common children, if any;
Custody and support of minor children determined in accordance with the best-interest-of-the-child rule.

Children conceived or born before the final judgment of nullity or annulment are considered legitimate (Article 54). For void marriages due to psychological incapacity, the same rule applies.

Property Relations

The property regime depends on the date of marriage. Marriages before 1988 follow the Civil Code regime; those after follow the Family Code. In the absence of a marriage settlement, the default is absolute community of property (Article 75 et seq.). The court orders the liquidation of the community or conjugal property upon the issuance of the decree.

Special Considerations

Children – The petition must include provisions for support, custody, and visitation rights.
Criminal Implications – If the secret marriage was bigamous or involved fraud, separate criminal charges (e.g., bigamy under Article 349 of the Revised Penal Code) may be filed.
Time and Cost – Cases typically take two to five years or longer, depending on docket congestion and complexity. Attorney’s fees, filing fees, and expert witness fees vary by region.
Foreign Marriages – If one party is a foreigner or the marriage was celebrated abroad, additional rules on recognition of foreign judgments or conflict of laws may apply, but the Family Code still governs the personal status of Filipino citizens.
Muslim Personal Law – For Muslims, the Code of Muslim Personal Laws (Presidential Decree No. 1083) may provide alternative grounds and procedures, including divorce by talaq, but unregistered marriages among Muslims still require compliance with registration requirements under that Code.

The law treats every marriage with the presumption of validity. Therefore, the burden of proving the existence of the marriage and the existence of a ground for nullity or annulment rests squarely on the petitioner. Courts exercise caution to prevent collusion or fraud, particularly in secret or unregistered cases where documentary evidence is scarce.

In sum, while unregistered and secret marriages are valid when the essential and formal requisites are met, their dissolution follows the same rigorous judicial process as registered marriages, with the added evidentiary burden of proving the marriage itself. Compliance with the Family Code and the Supreme Court’s procedural rules ensures that the rights of the parties, their children, and third persons are fully protected.
