Mutual Incompatibility as Grounds for Marriage Nullity in the Philippines: A Deep Dive

The Supreme Court's 2022 decision in Leilani Lim Go v. Hendrick N. Go (G.R. No. 258095) marks a significant development in Philippine family law. It applies the re-conceptualized understanding of psychological incapacity under Article 36 of the Family Code, first articulated in Tan-Andal v. Andal. The case clarifies that a marriage may be declared void not only because of a diagnosed personality disorder, but also because of the mutual incompatibility and antagonism between spouses rooted in their clashing personality structures. This article explains the facts, the legal framework, and the practical implications of this ruling.

The Facts of the Case

Leilani and Hendrick married in 1999 after Leilani became pregnant. From the start, the marriage was fraught with difficulties. Leilani testified about Hendrick's infidelity, his lack of emotional and financial support, and his dismissive attitude toward her needs. Hendrick, for his part, admitted he did not give his wife the attention and support she deserved but denied having an affair.

The couple separated in 2014. Interestingly, both parties agreed that they became better co-parents after separating. A clinical psychologist diagnosed Leilani with Passive Aggressive Personality Disorder and Hendrick with Avoidant Personality Disorder, concluding both conditions were permanent and grave. However, the psychologist only interviewed Leilani and her friend; Hendrick refused to participate.

The Legal Issue

The central question was whether the marriage could be declared void under Article 36 of the Family Code, which states that a marriage is void if either party was psychologically incapacitated to comply with the essential marital obligations at the time of the celebration, even if the incapacity becomes manifest only later.

The Court of Appeals reversed the trial court's grant of nullity, holding that the evidence was insufficient because the psychologist's findings were one-sided. The Supreme Court, however, reversed the Court of Appeals and granted the petition.

The Re-Conceptualized Framework

The Supreme Court applied the framework from Tan-Andal v. Andal, which shifted the focus away from personality disorders as the sole basis for psychological incapacity. Under this new concept, psychological incapacity consists of clear acts of dysfunctionality showing a lack of understanding and compliance with essential marital obligations due to psychic causes. Expert opinion is no longer required.

The Court also cited Laroco v. Laroco, which provided new guidelines for establishing psychological incapacity. Counsel must present clear and convincing evidence of acts, behavior, or circumstances of dysfunctionalities that are indicative of incompatibility and antagonism between spouses. These may include loss of love, hostility, distrust, inability to live harmoniously, and zero probability of reconciliation.

Application to the Case

Applying this framework, the Court found that Leilani and Hendrick's marriage was marked by mutual incompatibility and antagonism. The evidence showed:

• General differences of interests and antagonistic feelings
• Loss of love and hostility
• Distrust and indifference
• Inability to live harmoniously together
• Zero probability of reconciliation

The Court noted that while neither spouse was proven to have committed grave fault, their clashing personality structures made it impossible for them to function as a married couple. Their separation actually improved their relationship as co-parents. The Court held that this mutual incompatibility was grave, incurable, and had juridical antecedence—it existed before marriage but only manifested fully during cohabitation.

Practical Takeaways

• Expert opinion is no longer indispensable. While psychological evaluations remain helpful, ordinary witnesses who observed the spouses' behavior can now testify to establish psychological incapacity.
• Mutual incompatibility can be enough. A marriage may be declared void if the spouses' personality structures are so incompatible that the marriage inevitably breaks down, even without a diagnosed personality disorder.
• The three elements remain essential. Gravity, juridical antecedence, and incurability must still be proven with clear and convincing evidence.
• The list of dysfunctional behaviors is illustrative, not exclusive. Courts may consider infidelity, lack of communication, financial nonsupport, and other circumstances as evidence of psychological incapacity.
• Separation that improves co-parenting may support a finding of nullity. When spouses function better apart than together, this can demonstrate the irreparable breakdown of the marital union.
