A Philippine Legal Article

I. Introduction

In the Philippines, one of the most commonly invoked grounds to dissolve a marriage is psychological incapacity under Article 36 of the Family Code. It is often misunderstood as requiring a psychiatric diagnosis, hospital records, therapy notes, or expert testimony from a psychologist or psychiatrist. That is not strictly correct.

A marriage may be declared void on the ground of psychological incapacity even without medical records, provided the totality of evidence sufficiently proves that one or both spouses were psychologically incapacitated to comply with the essential marital obligations at the time of the marriage.

The key point is this: psychological incapacity is a legal concept, not purely a medical one. Medical or psychological evidence may help, but it is not always indispensable.

II. Nature of Psychological Incapacity Under Philippine Law

Article 36 of the Family Code provides that:

A marriage contracted by any party who, at the time of the celebration, was psychologically incapacitated to comply with the essential marital obligations of marriage shall be void, even if such incapacity becomes manifest only after its solemnization.

Psychological incapacity does not refer to ordinary marital difficulty, emotional immaturity, incompatibility, refusal to perform marital duties, or mere “bad behavior.” It refers to a serious incapacity that prevents a spouse from truly understanding, assuming, or complying with the essential obligations of marriage.

The marriage is considered void from the beginning, not merely voidable. This is why the action is usually called a petition for declaration of nullity of marriage, not technically annulment, although many people casually call it annulment.

III. Annulment vs. Declaration of Nullity

In Philippine law, “annulment” and “declaration of nullity” are different.

Annulment applies to valid marriages that may be annulled due to defects such as lack of parental consent, insanity, fraud, force, intimidation, impotence, or serious sexually transmissible disease.

Declaration of nullity applies to marriages that were void from the start, including marriages void under Article 36 because of psychological incapacity.

Thus, when people say “annulment based on psychological incapacity,” the technically correct term is usually:

Petition for Declaration of Nullity of Marriage under Article 36 of the Family Code.

Still, in common usage, many people refer to it as “annulment.”

IV. Essential Marital Obligations

Psychological incapacity must relate to the inability to comply with essential marital obligations, not just any marital expectation.

These obligations include, among others:

To live together as husband and wife;
To observe mutual love, respect, and fidelity;
To render mutual help and support;
To jointly manage the family;
To care for, support, and educate the children;
To maintain commitment to the marital union;
To assume the responsibilities of marriage in a real, stable, and enduring way.

The focus is not simply whether a spouse failed to do these things. The deeper question is whether the spouse was psychologically incapable of doing them in a legally significant sense.

V. Psychological Incapacity Without Medical Records

A petition may still prosper even if the petitioner has no:

Psychiatric hospital records;
Psychological treatment history;
Therapy records;
Medical diagnosis before or during marriage;
Prescription records;
Mental health certificates;
Written psychiatric evaluation from the incapacitated spouse.

This is because Philippine jurisprudence recognizes that psychological incapacity may be proven by the totality of evidence.

The court does not require proof beyond reasonable doubt. The required level of proof in civil cases is generally preponderance of evidence, meaning the evidence shows that the claim is more likely true than not.

Medical records may strengthen a case, but their absence does not automatically defeat it.

VI. Expert Testimony Is Helpful but Not Always Indispensable

Earlier case law placed heavy emphasis on psychological or psychiatric expert testimony. However, later jurisprudence clarified that the testimony of a physician, psychologist, or psychiatrist is not absolutely required in every Article 36 case.

The Supreme Court has recognized that courts may decide based on the totality of evidence presented, including testimony from the petitioner, relatives, friends, and other people who personally observed the spouses’ conduct before, during, and after the marriage.

This means a case may be built through:

Personal testimony;
Family testimony;
Documentary evidence;
Patterns of conduct;
Circumstantial evidence;
Admissions;
Communications;
Prior behavior;
Post-marriage conduct revealing a pre-existing incapacity.

The absence of medical records is not fatal if the evidence convincingly shows a grave, deeply rooted, and enduring incapacity that existed at the time of marriage.

VII. The Totality of Evidence Rule

The “totality of evidence” approach means the court examines all facts together, not in isolation.

A spouse’s isolated act of irresponsibility may not be enough. But a long-standing pattern of behavior may show psychological incapacity, especially when that pattern reveals an inability to understand or perform marital obligations.

For example, the following may be relevant:

Persistent abandonment of the family;
Habitual refusal to provide support despite ability;
Chronic infidelity showing incapacity for fidelity and commitment;
Repeated violence, cruelty, or abuse;
Severe narcissistic, antisocial, dependent, avoidant, or immature personality patterns;
Addiction that existed before marriage and rendered the spouse unable to perform marital duties;
Complete inability to form a stable marital partnership;
Extreme irresponsibility toward children;
Fraudulent or manipulative behavior showing inability to maintain trust and mutual respect;
Pattern of treating marriage as disposable or meaningless.

However, the court must be convinced that these are not merely voluntary acts, moral failings, or ordinary marital problems, but manifestations of psychological incapacity.

VIII. The Important Shift in Philippine Jurisprudence

Philippine law on psychological incapacity has evolved significantly.

For years, courts followed a strict interpretation requiring psychological incapacity to be:

Medically or clinically identified;
Existing at the time of marriage;
Grave;
Juridically antecedent;
Incurable or permanent.

These requirements were associated with the guidelines in Republic v. Court of Appeals and Molina.

Later cases softened the rigidity of Molina. The most important modern development is Tan-Andal v. Andal, where the Supreme Court clarified that psychological incapacity is not necessarily a medical illness. It is a legal incapacity that may be proven without a clinical diagnosis.

Under this more liberal approach, psychological incapacity remains serious, but it need not be proven only through medical or psychiatric evidence.

IX. Psychological Incapacity as a Legal, Not Medical, Concept

One of the most important principles is that psychological incapacity under Article 36 is a legal concept.

This means:

It does not have to be classified under a psychiatric manual;
It does not always require a formal mental disorder diagnosis;
It does not require that the spouse was confined in a hospital;
It does not require prior psychiatric treatment;
It does not require the incapacitated spouse to submit to examination.

The court looks at whether the spouse was truly incapable of complying with essential marital obligations.

A psychological report may explain the incapacity, but the judge makes the legal determination.

X. What Must Still Be Proven

Even without medical records, the petitioner must still prove key elements.

1. Gravity

The incapacity must be serious. It must not be mere difficulty, neglect, immaturity, or refusal.

The spouse must be truly unable, not merely unwilling, to comply with essential marital obligations.

2. Juridical Antecedence

The incapacity must have existed at the time of the marriage, even if it became obvious only later.

Evidence from childhood, adolescence, prior relationships, family background, early adult behavior, and conduct immediately before marriage may be relevant.

3. Incurability or Durability

The incapacity must be enduring or deeply rooted. It need not be absolutely incurable in a medical sense, but it must be so persistent and ingrained that the spouse cannot reasonably be expected to comply with marital obligations.

4. Relation to Essential Marital Obligations

The conduct must relate directly to marriage duties. General unpleasantness, personality clashes, or incompatibility are not enough.

XI. Evidence That May Substitute for Medical Records

Where medical records are absent, the petitioner may rely on other evidence.

A. Testimony of the Petitioner

The petitioner’s testimony is often central. It should describe:

How the parties met;
Conduct before marriage;
Events during marriage;
Specific acts showing incapacity;
Frequency and duration of the behavior;
Effect on the family;
Attempts to save the marriage;
Why the behavior shows incapacity, not merely conflict.

Vague statements such as “he was irresponsible” or “she was immature” are weak. Courts need concrete details.

B. Testimony of Relatives

Parents, siblings, children, in-laws, and other relatives may testify about:

The spouse’s personality before marriage;
Family history;
Long-standing behavioral patterns;
Abandonment, abuse, addiction, infidelity, or irresponsibility;
Attempts by the family to intervene;
The spouse’s inability to sustain family obligations.

C. Testimony of Friends, Neighbors, or Co-workers

Non-family witnesses can be persuasive because they may appear more neutral. They may testify about observed behavior, public incidents, admissions, or long-standing patterns.

D. Documentary Evidence

Documents may include:

Text messages;
Emails;
Social media messages;
Letters;
Barangay blotters;
Police reports;
Protection order records;
Financial records;
School records of children;
Employment records;
Records of abandonment;
Photographs;
Travel records;
Prior complaints;
Affidavits;
Written admissions.

E. Expert Evaluation Based on Collateral Information

Even without medical records, a psychologist may prepare a report based on interviews with the petitioner and collateral witnesses.

The expert may not personally examine the respondent if the respondent refuses to participate. That does not automatically invalidate the report, although it may affect weight.

The report should be careful, factual, and grounded in observed behavior.

XII. Can the Case Proceed If the Respondent Refuses Psychological Evaluation?

Yes.

A respondent cannot defeat an Article 36 petition simply by refusing to undergo psychological or psychiatric evaluation.

The court may consider evidence from the petitioner, witnesses, and documents. An expert may also render an opinion based on collateral sources, provided the limitations are disclosed.

However, the court will still evaluate whether the evidence is sufficient.

XIII. Common Situations Where There Are No Medical Records

Many Article 36 cases involve no prior medical records because:

The spouse never sought treatment;
The spouse denied having any problem;
The family viewed the behavior as moral or personal, not psychological;
Mental health services were inaccessible or unaffordable;
The spouse refused evaluation;
The incapacity became obvious only after marriage;
The behavior involved personality patterns rather than hospitalization-level mental illness.

Courts understand that not all psychologically incapacitated spouses have a formal medical history.

XIV. Examples of Conduct That May Support Psychological Incapacity

The following conduct may support a petition if proven to be grave, enduring, antecedent, and connected to essential marital obligations.

1. Chronic Infidelity

Infidelity alone does not automatically prove psychological incapacity. But a pattern of compulsive, shameless, or repeated infidelity, especially existing before marriage and continuing after marriage despite consequences, may show incapacity for fidelity and commitment.

2. Abandonment

A spouse who repeatedly abandons the family, refuses communication, rejects responsibility for children, and shows no capacity for marital partnership may be psychologically incapacitated.

3. Violence or Abuse

Repeated physical, emotional, psychological, or sexual abuse may show incapacity to observe love, respect, and mutual support.

However, the petitioner must show that the conduct reflects a deep incapacity, not merely isolated anger or ordinary conflict.

4. Substance Abuse or Addiction

Addiction may support psychological incapacity if it existed before the marriage or was deeply rooted and rendered the spouse incapable of fulfilling marital duties.

5. Extreme Irresponsibility

Persistent refusal to work, provide support, care for children, or participate in family life may be relevant, especially if it reflects a personality structure incompatible with marriage.

6. Narcissistic or Antisocial Patterns

Manipulation, lack of empathy, exploitation, deceit, aggression, and inability to maintain stable relationships may support a finding of incapacity.

7. Immaturity

Mere immaturity is not enough. But extreme, persistent, and deeply rooted immaturity that makes a spouse unable to assume marriage obligations may be considered.

XV. What Is Usually Not Enough

The following, by themselves, are usually insufficient:

Mere incompatibility;
Ordinary quarrels;
Financial problems alone;
Laziness without proof of incapacity;
One-time infidelity;
Temporary separation;
Falling out of love;
Refusal to have sex without deeper incapacity;
Personality differences;
Poor communication;
Religious differences;
Cultural differences;
Meddling in-laws;
Ordinary jealousy;
Marital disappointment;
Mutual resentment.

Article 36 is not a divorce substitute. It requires proof that a spouse was psychologically incapacitated from the beginning to assume essential marital obligations.

XVI. Importance of Juridical Antecedence Without Medical Records

Without medical records, proving juridical antecedence becomes more challenging but still possible.

The petitioner may show that the incapacity existed before marriage through:

Childhood history;
Family upbringing;
Previous unstable relationships;
Prior addictions;
Prior violence;
Long-standing irresponsibility;
Pre-marriage deceit;
Premarital abandonment;
Premarital infidelity;
Pre-existing personality patterns;
Testimony from people who knew the spouse before marriage.

Post-marriage conduct may also be used if it reveals a condition already existing before the wedding.

For example, if a spouse immediately abandons the marital home after marriage, refuses responsibility, and had a history of doing the same in prior relationships, the court may infer that the incapacity predated the marriage.

XVII. Role of the Psychologist Without Medical Records

A psychological report may still be useful even if there are no prior medical records.

The psychologist may rely on:

Clinical interview with the petitioner;
Interviews with collateral witnesses;
Psychological tests, if applicable;
Family history;
Relationship history;
Behavioral patterns;
Documents and communications;
Case records.

The expert’s task is not merely to assign a label. The report should explain:

The spouse’s personality structure;
How that structure developed;
How it existed before marriage;
How it prevented compliance with marital obligations;
Why the incapacity is grave and enduring.

A weak psychological report full of generic conclusions may be given little weight. A strong report links facts to legal elements.

XVIII. The Solicitor General and the State’s Role

In Article 36 cases, the State has an interest in protecting marriage. The Office of the Solicitor General, public prosecutor, or government counsel may participate or review the case, depending on procedural rules and practice.

The court must ensure there is no collusion between the spouses. Even if the respondent does not oppose the petition, the petitioner must still prove the case.

The absence of opposition is not automatic victory.

XIX. Procedure in an Article 36 Case

The general process usually involves:

Consultation with counsel;
Preparation of petition;
Filing in the proper Family Court;
Payment of docket fees;
Service of summons to respondent;
Investigation or certification against collusion;
Pre-trial;
Presentation of petitioner’s evidence;
Presentation of expert witness, if any;
Presentation of respondent’s evidence, if any;
Formal offer of evidence;
Decision;
Registration of judgment and decree, if granted.

The exact procedure may vary depending on current court rules, local practice, and whether the case is contested.

XX. Proper Venue

Petitions involving marriage and family relations are generally filed in the Family Court with jurisdiction over the proper residence of the parties, subject to procedural rules.

Venue can be technical. Filing in the wrong venue can delay or jeopardize the case.

XXI. Who May File

Generally, either spouse may file a petition for declaration of nullity based on psychological incapacity.

The incapacitated spouse may also be the petitioner. Philippine law does not require that only the “innocent” spouse file.

The issue is not fault, but whether there was psychological incapacity at the time of marriage.

XXII. Effect of Declaration of Nullity

If the court grants the petition, the marriage is declared void from the beginning.

However, this does not automatically settle every related issue. The court may also address:

Custody of children;
Support;
Property relations;
Liquidation of property regime;
Legitimacy of children;
Use of surname;
Registration of the decree;
Delivery of presumptive legitime, when applicable;
Other consequences under the Family Code.

Children conceived or born before the judgment of nullity under Article 36 are generally considered legitimate.

XXIII. Property Consequences

The property consequences depend on the applicable property regime and the circumstances of the marriage.

Possible regimes include:

Absolute community of property;
Conjugal partnership of gains;
Complete separation of property;
Co-ownership rules for void marriages.

The court may require liquidation, partition, and distribution of properties before issuance or registration of the final decree, depending on the applicable rules.

XXIV. Custody and Support

A declaration of nullity does not erase parental obligations.

Parents remain responsible for support, education, and care of their children. Custody is determined based on the best interests of the child.

A parent found psychologically incapacitated is not automatically deprived of custody, but the facts supporting incapacity may affect custody and visitation.

XXV. Remarriage After Declaration of Nullity

A person cannot simply remarry after receiving a favorable decision.

The judgment must become final, and the decree of nullity and related documents must be properly registered with the civil registry and other required offices.

Failure to comply with registration and decree requirements may create legal complications for a subsequent marriage.

XXVI. No Medical Records: Strengths and Weaknesses of the Case

Strengths

A case without medical records may still be strong if there is:

Clear testimony from multiple witnesses;
Consistent timeline;
Specific incidents;
Proof of pre-marriage roots;
Documentary evidence;
Expert explanation based on collateral sources;
Strong connection between conduct and marital obligations.

Weaknesses

The case may be weak if it relies only on:

General accusations;
Unsupported conclusions;
Emotional narratives without dates or details;
Ordinary marital conflict;
A single act of betrayal;
No evidence of pre-existing incapacity;
No witnesses other than petitioner;
No documents;
No explanation of gravity or durability.

XXVII. Practical Evidence Checklist

A petitioner without medical records should try to organize evidence by theme.

Before Marriage

Behavior during courtship;
Prior relationships;
Family background;
Work history;
Addiction history;
Violence or abuse history;
Irresponsibility or abandonment patterns;
Premarital deception;
Witnesses who knew the spouse before marriage.

During Marriage

Dates of incidents;
Abandonment;
Infidelity;
Abuse;
Financial neglect;
Refusal to care for children;
Lack of emotional support;
Manipulation or cruelty;
Communications proving behavior;
Barangay or police records;
Medical records of the victim, if abuse occurred.

After Separation

Continued refusal of responsibility;
Lack of support;
Continued abusive behavior;
New relationships showing recurring pattern;
Admissions;
Failure to communicate with children;
Attempts at reconciliation and failure.

XXVIII. How to Present the Case Without Medical Records

The petition should not merely say that the respondent is psychologically incapacitated. It should narrate facts showing why.

A strong presentation usually follows this structure:

Background of the parties;
Courtship and pre-marriage behavior;
Wedding and early married life;
Manifestations of incapacity;
Impact on marital obligations;
History showing antecedence;
Explanation of gravity;
Explanation of incurability or durability;
Supporting witnesses and documents;
Expert opinion, if available.

The court must see a coherent story: the spouse’s behavior was not random, temporary, or ordinary; it was the manifestation of a deep incapacity to enter and sustain marriage.

XXIX. Importance of Specificity

Courts are more persuaded by specific facts than labels.

Weak allegation:

“My husband was irresponsible and immature.”

Stronger allegation:

“Even before the wedding, he repeatedly disappeared for days without explanation, refused stable employment, borrowed money from my parents while concealing gambling losses, and admitted he did not believe he had any duty to support a family. After the wedding, the same pattern continued. He left the marital home several times, failed to provide support despite employment, and ignored our child’s needs.”

The second version gives the court facts from which incapacity may be evaluated.

XXX. Psychological Incapacity of Both Spouses

A petition may allege psychological incapacity of one spouse or both spouses.

Sometimes both parties may have personality structures that made them incapable of assuming marriage obligations. However, the petitioner should be careful. Alleging one’s own incapacity may have implications in custody, credibility, and related issues.

The legal issue remains whether the marriage was void because of incapacity existing at the time of celebration.

XXXI. Collusion Concerns

If both spouses agree to the nullity, the court will still examine whether the case is collusive.

Collusion may exist where parties fabricate facts or suppress evidence to obtain a favorable judgment.

The petitioner must present real evidence. Agreement between spouses does not substitute for proof.

XXXII. The Respondent’s Non-Appearance

If the respondent does not appear despite proper service of summons, the case may proceed. But the petitioner must still prove psychological incapacity.

Default or non-participation does not automatically establish the ground.

The court may still deny the petition if the evidence is insufficient.

XXXIII. Common Defenses

A respondent may argue that:

The alleged acts are false;
The petitioner caused the marital breakdown;
The problems arose only after marriage;
The behavior was voluntary, not incapacity;
The conduct was isolated;
The petitioner tolerated or exaggerated the behavior;
There was no proof of juridical antecedence;
There is no expert evidence;
The witnesses are biased;
The case is collusive.

A good petition anticipates these defenses by presenting objective and consistent evidence.

XXXIV. Psychological Incapacity and Abuse

Where abuse is involved, the petitioner should consider both the nullity case and protective remedies.

Psychological incapacity may be relevant if the abusive spouse’s conduct shows an inability to observe mutual love, respect, fidelity, and support. But if there is immediate danger, remedies under laws protecting women, children, or victims of violence may be more urgent.

A nullity case is not a substitute for protection orders or criminal remedies where abuse is present.

XXXV. Psychological Incapacity and Infidelity

Infidelity is one of the most common factual bases alleged in Article 36 cases, but it is also commonly misunderstood.

A single affair may show betrayal, but not necessarily psychological incapacity. The petitioner must show that the infidelity is part of a deeper incapacity, such as:

Compulsive pattern of affairs;
Inability to maintain exclusive commitment;
Lack of remorse or empathy;
Repetition despite harm to spouse and children;
Premarital roots;
Long-standing personality pattern.

The issue is not simply adultery or concubinage. The issue is incapacity to comply with fidelity and commitment as essential marital obligations.

XXXVI. Psychological Incapacity and Abandonment

Abandonment may be persuasive if it shows more than a temporary separation.

Relevant details include:

When the spouse left;
Whether there was justification;
Whether support was provided;
Whether children were abandoned;
Whether the spouse showed concern;
Whether the spouse had a history of abandonment;
Whether the spouse repeatedly returned and left;
Whether the conduct began soon after marriage.

Abandonment that reflects a fundamental inability to commit may support Article 36.

XXXVII. Psychological Incapacity and Addiction

Addiction may support a petition where it is grave and deeply rooted.

Important facts include:

When the addiction began;
Whether it existed before marriage;
Its effect on work, finances, children, and family life;
Failed attempts at rehabilitation;
Denial of the problem;
Related violence or neglect;
Recurrence over time.

Addiction arising only after marriage may still be relevant but may create difficulty in proving juridical antecedence unless linked to a pre-existing personality structure or earlier pattern.

XXXVIII. Psychological Incapacity and Financial Irresponsibility

Financial irresponsibility alone does not necessarily prove psychological incapacity.

However, a spouse who persistently refuses to work, squanders family resources, incurs debts, abandons support obligations, and shows no capacity for responsible family life may be psychologically incapacitated.

Evidence may include:

Loan documents;
Bank records;
Pawnshop records;
Gambling records;
Messages demanding money;
School fee records;
Proof of unpaid support;
Witness testimony.

The key is connecting financial irresponsibility to incapacity to assume marital and parental obligations.

XXXIX. Psychological Incapacity and Personality Disorders

A formal diagnosis of personality disorder may help, but it is not mandatory.

Possible personality patterns relevant to Article 36 may include narcissistic, antisocial, borderline, dependent, avoidant, or immature personality traits. But the label alone is not enough.

The court will examine how the personality structure affects marital obligations.

A spouse may have difficult traits but still be legally capable of marriage. Conversely, a spouse may lack a formal diagnosis but still be legally incapacitated under Article 36.

XL. Weight of Expert Testimony

Expert testimony is not automatically controlling.

The court may reject an expert report if it is speculative, biased, generic, or unsupported by facts. The expert must explain the basis of the opinion.

A strong expert report usually:

Identifies factual basis;
Explains methodology;
Discusses family and developmental history;
Links behavior to marital obligations;
Explains juridical antecedence;
Explains gravity;
Explains durability or incurability;
Avoids unsupported conclusions.

XLI. What If There Is No Expert Witness at All?

A petition may theoretically succeed without an expert witness if the lay testimony and documentary evidence are strong enough.

However, in practice, expert testimony often helps organize the psychological explanation and bridge the facts with the legal standard.

The absence of both medical records and expert testimony may make the case harder, but not necessarily impossible.

XLII. Burden of Proof

The petitioner has the burden of proving psychological incapacity.

The court will not presume incapacity from marital failure alone. The law presumes marriage to be valid, and the petitioner must overcome that presumption.

This is why evidence must be detailed, consistent, and credible.

XLIII. Drafting the Petition Without Medical Records

The petition should avoid overreliance on conclusions.

Instead of repeatedly saying “respondent is psychologically incapacitated,” it should plead facts showing:

What the respondent did;
When the behavior began;
How often it happened;
Who witnessed it;
How it affected marital obligations;
Why it existed before marriage;
Why it is grave;
Why it is enduring;
What evidence supports it.

The petition should also identify witnesses and documents.

XLIV. The Danger of Fabricated or Exaggerated Claims

Because Article 36 cases often involve private family matters, courts are alert to fabricated or exaggerated claims.

False allegations can damage credibility and may expose parties to legal consequences.

A case without medical records must be especially careful to rely on truthful, specific, and corroborated facts.

XLV. Possible Outcomes

The court may:

Grant the petition and declare the marriage void;
Deny the petition for insufficient evidence;
Require further proceedings;
Give little weight to weak expert testimony;
Consider the case collusive if facts appear fabricated;
Rule on custody, support, and property consequences.

Even if the marriage is clearly broken, the petition may still be denied if psychological incapacity is not proven.

XLVI. Strategic Considerations

A petitioner without medical records should consider:

Gathering witnesses who knew the respondent before marriage;
Preserving messages, emails, and documents;
Preparing a clear timeline;
Consulting a psychologist familiar with Article 36 cases;
Avoiding vague allegations;
Showing attempts to save the marriage;
Demonstrating that the incapacity is not merely refusal;
Connecting facts to essential marital obligations.

The strongest cases are fact-rich, consistent, and supported by multiple sources.

XLVII. Sample Theory of the Case

A possible theory may be:

The respondent’s conduct before, during, and after the marriage shows a deeply rooted personality structure marked by irresponsibility, lack of empathy, inability to sustain commitment, and refusal to assume family obligations. This incapacity existed before the marriage, became fully manifest during the marriage, and rendered the respondent incapable of complying with the essential obligations of mutual love, respect, fidelity, support, cohabitation, and parental responsibility.

This theory must then be supported by actual facts.

XLVIII. Sample Evidence Matrix

Legal Element	Evidence Needed	Possible Proof Without Medical Records
Gravity	Serious inability to perform marital duties	Repeated abandonment, abuse, addiction, chronic infidelity
Juridical antecedence	Existed at time of marriage	Premarital history, family testimony, prior relationships
Durability	Deeply rooted and persistent	Long pattern over many years, failed interventions
Link to obligations	Direct effect on marriage duties	Non-support, lack of fidelity, refusal to care for children
Credibility	Reliable and consistent proof	Witnesses, documents, messages, records

XLIX. Common Mistakes in Article 36 Cases Without Medical Records

Common mistakes include:

Treating Article 36 as divorce;
Relying only on emotional pain;
Presenting no witness except the petitioner;
Failing to prove premarital roots;
Confusing refusal with incapacity;
Using generic psychological reports;
Alleging conclusions instead of facts;
Ignoring property and custody consequences;
Assuming respondent’s absence guarantees success;
Failing to register the final decree properly.

L. Conclusion

A Philippine petition for declaration of nullity based on psychological incapacity may proceed and may even succeed without medical records. Medical documentation is useful, but it is not the sole means of proving psychological incapacity.

The decisive question is whether the totality of evidence shows that, at the time of marriage, one or both spouses suffered from a grave, enduring, and legally significant incapacity to comply with essential marital obligations.

The absence of medical records shifts the emphasis to credible testimony, corroborating witnesses, documents, behavioral history, and a clear explanation of how the spouse’s conduct reflects incapacity rather than ordinary marital failure.

In Philippine law, psychological incapacity is not simply a medical diagnosis. It is a legal finding based on the facts of the case. A well-prepared petition without medical records must therefore tell a coherent, specific, and evidence-based story showing that the marriage was void from the beginning because the spouse was never truly capable of assuming the obligations of marriage.
