Grounds for divorce in Thailand: statutory fault and consent
Thai divorce law is not no-fault by default. Section 1516 of the Civil and Commercial Code lists ten statutory grounds including adultery, misconduct, desertion, and failure to maintain. Each ground requires specific facts and evidence at family court. The eleventh path is mutual consent at amphoe, where neither spouse proves fault but both sign a complete agreement on property, custody, and surname. Choosing the wrong route wastes months and amphoe fees.
At Thai Visa Centre in Bangkok we coordinate visa planning and referrals to licensed Thai family counsel. Marriage visa holders need a new category before divorce is final. For related topics, see our contested divorce guide and uncontested divorce guide.
Thai Civil and Commercial Code lists ten fault-based grounds for contested divorce at family court.
Mutual consent at amphoe does not require proving fault. Both spouses sign before the district registrar.
Each ground requires specific facts. Adultery needs credible evidence. Desertion needs continuous absence.
We support administrative divorce and visa planning. Contested grounds litigation needs Thai family counsel.
Primary statutory grounds explained
Each ground requires specific facts under the Civil and Commercial Code. The table below explains four of the most commonly cited grounds in contested cases.
| Ground | Requirements |
|---|---|
| Adultery | One spouse has maintained another person as husband or wife, or had regular sexual intercourse with another person. Credible evidence required. |
| Misconduct | Serious misconduct or dishonourable behaviour causing the other spouse to suffer insult or hatred making cohabitation impossible. |
| Desertion | One spouse has deserted the other for more than one year. Continuous absence must be proven. |
| Failure to maintain | One spouse has failed to provide proper maintenance and support despite ability to do so. |
Additional statutory grounds
Thai law also recognises these additional fault grounds for contested divorce at family court. Your lawyer confirms which apply to your facts.
- Serious harm or physical abuse making cohabitation dangerous or intolerable
- One spouse has been sentenced to imprisonment for more than one year
- One spouse has been insane for more than three years without prospect of recovery
- One spouse has broken a bond of good behaviour executed by the other
- One spouse has a communicable and dangerous disease making cohabitation unsafe
- One spouse has a physical disadvantage permanently preventing cohabitation as husband and wife
Choosing the right route
Assess available grounds
Family lawyer maps your facts against each Section 1516 ground and confirms whether mutual consent at amphoe remains available if both spouses still agree on terms.
Gather ground-specific evidence
Adultery needs credible proof. Desertion needs one year continuous absence. Misconduct needs facts showing cohabitation became intolerable. Evidence type differs for each ground.
Choose forum
Mutual consent without fault proof proceeds at amphoe with written agreement. Contested fault-based divorce proceeds at family court with complaint citing specific ground.
File or register
Family court complaint with ground cited and exhibits attached, or both spouses attend amphoe with complete property and custody agreement.
Plan visa impact
Marriage visa basis ends when divorce is final regardless of route. Map retirement, employment, or departure before overstay regardless of whether you used fault grounds or consent.
Immigration after divorce
Regardless of which ground or route is used, divorce ends the marriage visa basis. Plan immigration before divorce is registered.
- A Non-Immigrant O marriage visa loses its basis when marriage ends. Plan a new visa category or departure before overstay.
- Retirement, Elite, and DTV visas are generally unaffected unless tied to spouse finances or sponsorship.
- Fault grounds litigation may take years. Maintain lawful visa status throughout contested proceedings.
- Check visa category options at the Thailand e-Visa portal before divorce is finalised.
TVC coordination: We help clients plan visa category changes and coordinate administrative divorce where both spouses agree. Contested grounds litigation requires licensed Thai family lawyers.
Documents typically required
Gather these documents before choosing amphoe consent route or family court contested filing.
- Passports or Thai national ID cards for both parties
- Original marriage certificate registered in Thailand or recognised abroad
- Written agreement on property division and child custody for administrative route
- Translated and legalised documents if marriage was registered abroad
- Court pleadings and evidence supporting claimed statutory ground for contested cases
Common mistakes foreigners make
- Filing contested divorce without evidence sufficient for the statutory ground claimed.
- Assuming adultery can be proven by suspicion alone without documentary or witness support.
- Using amphoe consent route when spouse disputes property or custody terms.
- Not planning visa category change before marriage visa basis ends.
- Confusing Thai statutory grounds with divorce law from country of original marriage.

Timeline expectations
Mutual consent at amphoe may complete in one visit when documents are ready. Contested fault-based divorce at family court runs months to years depending on evidence and custody disputes.
Foreign marriage certificate legalisation may add weeks before any divorce route can proceed. Start document preparation early.
Frequently asked questions
General answers on grounds for divorce in Thailand. This is orientation, not legal advice. Consult licensed Thai family counsel for your specific case.
Q:Which ground is most common?
A:Mutual consent at amphoe is the most common path overall because no fault must be proven. Among contested family court filings, adultery and desertion appear frequently when spouses disagree on terms.
Q:How long does contested divorce take?
A:Six months to three years depending on quality of fault evidence, custody disputes, and whether a spouse must be served outside Thailand through diplomatic channels.
Q:Does TVC handle divorce court cases?
A:We support amphoe coordination and visa impact planning. Contested fault litigation at family court requires licensed Thai family counsel to plead specific Section 1516 grounds.
Q:Do I need to prove fault for amphoe divorce?
A:No. Mutual consent at amphoe requires both spouses to agree and sign a complete property and custody agreement. No statutory fault ground must be proven or cited.
Q:What evidence proves adultery?
A:Credible witness testimony, photographs, hotel records, messages, or other documentary proof showing regular sexual intercourse or maintaining another as spouse. Suspicion alone is insufficient at family court.
Q:Can I use desertion if my spouse lives abroad?
A:Possibly if continuous absence exceeds one year and other Civil and Commercial Code requirements are met. Service abroad and jurisdiction add complexity. Your family lawyer confirms before filing.
Q:How does divorce affect my marriage visa?
A:Non-Immigrant O marriage visa basis ends when divorce is final at amphoe or family court. Plan retirement, employment, DTV, or departure before overstay regardless of which ground or route you used.
Q:Are foreign marriages recognised for Thai divorce?
A:Foreign marriage certificates often require certified Thai translation and MFA legalisation before amphoe or family court accepts them. Recognition analysis by counsel is recommended before you choose a route.
