Thai Probate Explained: How the Court Process Works for Overseas Families

When a relative dies in Thailand, their assets cannot be accessed or transferred until the Thai courts formally appoint an estate administrator. This legal process is known as probate. It is required for most estates, including those with bank accounts, property, vehicles or company shares. For families overseas, the process can feel unfamiliar and often overwhelming, especially when urgent financial matters need attention.

This guide explains how Thai probate works in clear and practical terms for overseas families of the deceased. It outlines the documents you need, how the Thai courts handle applications and how everything can be managed from overseas with the support of a representative. The aim is to give you confidence, clarity and a straightforward understanding of what to expect.

Why Probate Matters in Thailand

Thai probate is the legal process that authorises someone to administer the estate. Banks, the land office, brokers and financial institutions cannot release assets until the court appoints the administrator. Probate protects the estate, confirms who the lawful heirs are and ensures that debts and obligations are handled correctly.

Families are often surprised to learn that probate is required even when there is a will or when the surviving spouse is the only heir. A foreign will or family agreement is not enough, as Thai institutions can only act once the court order is issued.

While probate is required in most cases, the process is often more straightforward where a clear and locally compliant will exists. A properly drafted Thai will helps the court confirm intent, appoint an executor or administrator more quickly and reduce unnecessary procedural delays, particularly where assets and family members are based in different countries.

Most families do not need to travel to Thailand. A representative can manage every step through a properly executed and legalised power of attorney.

Why Early Succession Planning Reduces Probate Delays

Many families are surprised by how involved the probate process can be, even where a will exists or where the surviving spouse is the only heir. For expats with assets in Thailand, structured succession planning can help reduce probate delays and uncertainty by clarifying authority, aligning wills with Thai law and ensuring documentation is prepared in advance.

What Probate Is Under Thai Law

Probate applies to assets located in Thailand. These commonly include:

• Bank accounts
• Condominium units and other property
• Vehicles
• Company shares
• Investments and securities

The court reviews the will if one exists, confirms who the heirs are and appoints an estate administrator. This appointment gives the administrator the legal authority to act on behalf of the estate.

When Probate Might Not Be Required

These situations are limited but possible:

• The deceased left no assets in Thailand
• A Thai bank allows release of a small balance (often between THB 50,000 and 200,000) without probate. (Please note that this is not a standard procedure and is subject to the bank manager’s discretion. The heir should check directly with the bank where the funds are held.)
• The asset is held through a structure that does not require probate

The small-balance exception is not universal and depends on the bank.

Who Can Apply for Probate

Several people may apply to administer a Thai estate, including:

• The spouse
• An adult child
• A parent
• A sibling or half-sibling
• A person named as executor in a will
• A person with a legitimate interest in the estate

Applicants must be at least twenty years old, of sound mind and not bankrupt.

Since 23 January 2025, same-sex spouses have identical inheritance and probate rights under amendments to the Civil and Commercial Code. A same-sex spouse is therefore eligible to apply and be appointed as administrator.

If more than one person wishes to act, the court decides who is best placed to manage the estate.

Foreign applicants may act but usually appoint a representative in Thailand.

Documents Required for a Thai Probate Application

The court usually requests:

• Thai death certificate with certified copies
• Deceased’s passport
• Applicant’s passport
• Proof of relationship, such as a marriage certificate or birth certificate
• Any Thai will
• A consent letter from other heir(s)
• A family tree
• Any foreign will covering Thai assets
• Thai translations of all foreign documents
• Legalisation by the Thai embassy or the Ministry of Foreign Affairs
• Power of attorney if the applicant is overseas
• A list of known Thai assets

Foreign powers of attorney must be notarised, legalised and translated. Thailand is not part of the Hague Apostille Convention, so legalisation is essential.

Thai Will vs Foreign Will: What the Court Accepts 

Thai Will

A Thai will is normally the clearest and most efficient route. It must be in writing, dated and signed before two witnesses. No notarisation is required.

Foreign Will

A foreign will can be accepted once the court is satisfied that it is:

• Translated into Thai
• Properly legalised
• Valid under the law of the country where it was made

Validation is not automatic. The court reviews the documents and may request additional evidence. It is important to note that a Thai court only has jurisdiction over property and assets located in Thailand. 

No will (Intestacy)

If there is no will, Thai intestacy rules apply. There are six classes of statutory heirs:

1. Children
2. Parents
3. Siblings who share both parents
4. Half-siblings
5. Grandparents
6. Aunts and uncles

A surviving spouse receives a share of the estate alongside heirs in Classes 1 to 4 or receives the entire estate if none of these classes exist. Learn more about statutory heirs in Thailand.

Step-by-Step: How the Thai Probate Process Works 

Step 1: Gather Documents

Collect the Thai death certificate, personal identification documents and any will. Gather proof of relationship and any known asset information. 

Step 2: Appoint A Representative

Most overseas families appoint a representative in Thailand through a legalised power of attorney. The representative works with a lawyer to prepare the probate petition. 

Step 3: Prepare the Probate Petition

The petition outlines the relationship, the existence of any will, the heirs and the known assets. 

Step 4: File the petition at the Correct Court

Applications are filed at the provincial court where the deceased lived or where their assets are located. The court may require a notice to be published for creditors or potential heirs. 

Step 5: Court Schedules a Hearing

The hearing date is set. Timing depends on court workload. Delays are common in Bangkok due to increased probate cases. 

Step 6: Probate Hearing

The judge examines the documents, confirms the applicant’s eligibility and reviews any will. The representative attends on behalf of the applicant. 

Step 7: Appointment of Estate Administrator

If accepted, the court issues the order appointing the administrator. 

Step 8: Administrator Manages the Estate

The administrator gathers assets, works with banks and authorities, settles debts and arranges distribution.

What Happens at the Court Hearing

Probate hearings are usually brief, provided the documents are in order. The judge may ask questions about:

• The death
• The applicant’s relationship to the deceased
• Whether heirs have been notified
• Whether a will exists
• What assets are in Thailand

Complex cases may require additional evidence or more than one hearing. Overseas families rarely need to attend in person.

Timeline: How Long Thai Probate Takes in 2026

Probate timelines vary. The following is a realistic guide for most cases:

• Document gathering: 1 to 3 weeks
• Translations and legalisations: 2 to 7 days, with MFA appointments often booked 1 to 2 weeks ahead
• Petition preparation: 1 to 2 weeks
• Court scheduling: 8 to 12 weeks
• Hearing to order issuance: 2 to 6 weeks
• Administrator actions: 1 to 4 weeks

A reasonable overall timeframe for most estates is four to twelve months. Complex cases, disputes, foreign wills or missing documents can extend the process to over a year.

Some banks may release small balances without probate. Anything above the bank’s threshold requires the full probate process.

Once probate is underway, families often need structured estate settlement and inheritance management to coordinate court filings, documentation, bank access and ongoing administration from overseas.

Costs Involved

Costs depend on complexity and location.

Typical costs include:

• Court filing fees
• Publication fees for creditor notices
• Translation fees, often THB 800 to 1,050 per page
• MFA and embassy legalisations
• Legal representation
• Representative fees

Legal fees commonly fall between THB 100,000 and 300,000, although complex cases may be higher.

Inflation in 2025 has increased some fees, especially for translation and legalisation services.

Estate assets can usually cover these costs once the administrator is appointed.

Duties of the Estate Administrator

Once appointed, the administrator is legally responsible for:

• Locating and collecting all assets
• Accessing and closing bank accounts
• Obtaining bank statements and balances
• Handling debts and financial obligations
• Managing or selling property if required
• Preparing inventories where needed
• Distributing assets according to the will or intestacy rules
• Providing a final report to the court if requested

The administrator must act in the best interests of the estate and may be held liable for losses resulting from improper actions.

Common Problems Families Face During Probate

Families overseas often encounter similar challenges, including:

• Difficulty identifying all bank accounts
• Differences in name spellings between Thai and foreign documents
• Missing or unregistered wills
• Assets located in multiple provinces
• Incorrect expectations regarding joint accounts
• Incorrect or incomplete powers of attorney
• Delays from MFA legalisation queues
• Bank KYC or biometric requirements for heirs
• Court backlogs, especially in Bangkok

A representative can resolve these issues and keep the case on track.
