Spousal Support

The introduction of Spousal Support Leave (officially categorized as Parental Leave or Spousal-Support in the Labour Protection Act (No. 9) B.E. 2568 (2025). This represents a historic shift in Thailand’s social and legal fabric. The social security act.  Effective December 7, 2025, this law bridges a massive gap between the public and private sectors while simultaneously serving as one of the first major practical applications of the Marriage Equality Act, which legalized same-sex marriage.

1. The Legal Milestone: From Fatherhood to Spousal Support. Historically, paternity leave in Thailand was a benefit reserved exclusively for government officials. Private-sector employees had no statutory right to leave after their partner gave birth, often forcing them to use personal business leave or annual vacation days.

The 2025 amendment dismantles this disparity. Under Section 41/3 of the amended Act, any employee whose lawful spouse gives birth is now entitled to 15 days of leave.

The Gender-Neutral Revolution

Crucially, the law uses the term Spouse; rather than Father.  This intentional phrasing aligns with the Marriage Equality Act B.E. 2567, which replaced the gendered terms husband and wife with the neutral spouses.

Same-Sex Couples: A woman whose female spouse gives birth is entitled to these 15 days to assist in recovery and childcare.

Transgender Parents: Any registered spouse, regardless of their gender identity or biological role in the pregnancy, holds the same 15-day entitlement.

2. Payout and Duration: The Employer’s Obligation

Unlike the 120-day maternity leave, which is split between the employer and the Social Security Office, the Spousal Support Leave is a direct employer-paid benefit.

Duration: 15 Days (Note: The law currently specifies 15 calendar days. Wage Guarantee: The employer must pay 100% of the normal wage for the entire 15-day duration.

The 90-Day Window: To provide flexibility for the diverse needs of newborn care, the leave can be taken either immediately before or within 90 days after the date of childbirth.

3. The Lawful Spouse Requirement

The most important caveat in the 2026 landscape is the definition of spouse.To  qualify for this 15-day paid leave, the couple must be legally married and registered under Thai law.

Registered Marriage: Partners must hold a valid Thai Marriage Certificate.

Common-Law Partners: In 2026, common-law or de facto partners who have not registered their marriage at a district office (Amphur) do not have a statutory right to this leave.

Same-Sex Registration: For same-sex couples, this means that those who registered their marriage after the January 2025 effective date are fully covered.

4. Strategic Implementation for HR and Businesses

As of March 2026, many companies are still adjusting their payroll and HR software to account for this new leave category.

Compliance Best Practices

Proof of Marriage: Employers are entitled to request a copy of the Marriage

Certificate to verify eligibility.

Proof of Birth: A copy of the Birth Certificate or a medical document confirming the delivery date is required to verify the 90-day window.

Non-consecutive Usage: While the law is silent on whether the 15 days must be taken all at once, most Thai labor experts recommend that employers allow split usage (e.g., 5 days at birth and 10 days later for medical check-ups) to maximize the support intent of the law.

5. The Cultural Impact: Promoting Dual-Parenting

This policy is a cornerstone of the Thai government’s effort to address the record-low birth rate (1.2). By mandating that employers pay for spousal leave, the state is making a clear declaration: childcare is no longer just a mothers job.

For same-sex families, this provides more than just time off; it provides legal validation. For the first time, a non-biological parent in a same-sex union has a recognized, paid role in the arrival of their child, supported by the full weight of the Labour Protection Act.
