Probate in Thailand: With a Will vs Without a Will
When dealing with the loss of a loved one in Thailand, one of the first legal questions families face is whether probate is required and whether the existence of a will makes the process easier or faster.
A common misconception among international families is that having a will avoids probate. Under Thai law, this assumption is incorrect.
Whether a person dies with a will or without a will, probate remains a mandatory legal process in Thailand. However, the procedures, risks, and outcomes differ significantly between the two situations. Understanding these differences is essential for protecting heirs’ rights and ensuring that the estate is administered lawfully.
Probate in Thailand When There Is a Will
1. Does a Will Automatically Take Effect?
No.
A will does not automatically give executors or beneficiaries the authority to act. Even if the will is clear and uncontested, it must first be submitted to the Thai court for probate.
The court will review:
- Whether the will complies with Thai legal requirements
- Whether the will is the most recent version
- Whether there are objections from heirs
Only after the court accepts the will and appoints an estate administrator can the estate be managed.
2. Advantages of Having a Will
Having a valid will generally provides:
- Clear expression of the deceased’s wishes
- Greater certainty in asset distribution
- Reduced risk of disputes among heirs
- More flexibility in appointing an estate administrator
For international clients, a properly drafted will can significantly simplify the probate process, provided it complies with Thai law or is recognized by the Thai court.

3. Risks Even When a Will Exists
Despite its advantages, a will does not eliminate all risks. Common issues include:
- Wills that do not meet Thai formalities
- Conflicting wills executed in different countries
- Ambiguous wording regarding assets or beneficiaries
- Challenges from statutory heirs
In such cases, probate proceedings may become prolonged or contested.
Revocation of Testamentary Provisions by Disposal or Destruction of Property
Even where a valid will exists, it is important to understand that certain testamentary provisions may be deemed revoked under Thai law, depending on the actions of the testator during their lifetime.
Under Section 1696 of the Thai Civil and Commercial Code, if a testator has intentionally transferred ownership of the property that is the subject of a specific testamentary provision, such provision is deemed revoked.
The same legal principle applies where the testator has intentionally destroyed the property that was designated under the will.
In practical terms, this means that:
- If a will leaves a specific asset to a beneficiary, but
- The testator later sells, transfers, or otherwise disposes of that asset during their lifetime with intent, or
- The testator intentionally destroys that asset,
then the corresponding clause in the will no longer has legal effect.
Practical Implications for Probate and Estate Administration
This provision often surprises heirs and beneficiaries, particularly in probate cases involving real estate, vehicles, or business assets.
Common examples include:
- A will bequeathing a specific condominium unit that was later sold by the deceased
- A will leaving a vehicle or business asset that no longer exists at the time of death
- Asset restructuring during the testator’s lifetime without updating the will
In such cases, the Thai court will treat the relevant testamentary clause as revoked, and the disposed or destroyed asset will not form part of the estate under that provision.
Why Regular Will Reviews Are Essential
Section 1696 highlights the importance of reviewing and updating a will whenever significant assets are sold, transferred, or restructured. Failure to do so may result in unintended consequences, including partial intestacy or disputes among heirs.
For international clients with changing asset portfolios in Thailand, regular legal review is strongly recommended to ensure that testamentary intentions remain aligned with current asset ownership.

How This Affects Probate Proceedings
During probate, the Thai court will examine not only the existence of a will, but also whether specific testamentary provisions remain legally effective at the time of death. Where Section 1696 applies, the court may disregard certain clauses and administer the estate accordingly.
This underscores the importance of professional legal assistance in both estate planning and probate proceedings, particularly where asset ownership has changed over time.
Probate in Thailand When There Is No Will (Intestate Succession)
When a person dies without leaving a valid will, the estate is distributed according to statutory inheritance rules under the Thai Civil and Commercial Code.
Challenges of Intestate Probate
Probate without a will is often more complex and risky because:
- The deceased’s intentions are unknown
- Asset distribution follows strict legal rules
- Family expectations may conflict with the law
- Disputes among heirs are more likely
The court must carefully determine heirship, which may require extensive documentation and hearings especially when heirs live overseas.
Key Differences: Probate With a Will vs Without a Will

| Probate required | Yes | Yes |
| Distribution of assets | According to will | According to statutory law |
