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:
- Children
- Parents
- Siblings who share both parents
- Half-siblings
- Grandparents
- 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.

Frequently Asked Questions
Probate Overseas Families
You usually need probate even when a valid will exists. Thai banks, the Land Office, and most institutions require a court order before releasing assets.
A will guides the court and confirms how the estate should be distributed, yet it does not give automatic legal authority to act. The Thai court must still appoint an estate administrator who then holds the legal right to access accounts, deal with property and manage the estate. A Thai will is normally accepted quickly. A foreign will requires translation and legalisation before the court can review it.
Yes. Most overseas families complete probate without travelling. A representative can appear in court on your behalf.
You can appoint a representative through a properly prepared and legalised power of attorney. They work with a lawyer to gather documents, prepare the probate petition, attend the hearing and manage the estate once the court issues the order. This ensures the process continues smoothly while you remain overseas.
Most probate cases take four to eight months. Simple cases in smaller provinces can be faster.
Timeframes depend on court workloads, the need for translations and legalisations and whether all documents are complete. Bangkok courts can take longer due to increased expat estates. Complex cases, foreign wills or disputes can extend the process beyond twelve months. Your representative can give a more precise estimate after reviewing your documents.
You need the Thai death certificate, identification documents, proof of relationship and any will. All foreign documents must be translated and legalised.
The court typically requires the Thai death certificate, the deceased’s passport, the applicant’s passport, a marriage certificate or birth certificate to confirm relationships, a family tree, a consent letter from other heirs and any Thai or foreign will. Foreign documents must be translated into Thai and legalised by the Thai embassy or the Ministry of Foreign Affairs. A power of attorney is needed if you wish to appoint a representative.
The estate passes according to Thai intestacy rules. The court applies a fixed order of statutory heirs.
There are six classes of heirs under the Civil and Commercial Code. Children, parents and siblings are the most common. The surviving spouse receives a share of the estate as well or the entire estate if no statutory heirs remain. The court appoints an administrator who then collects and distributes the assets. Probate is still required as institutions cannot release assets without a court order.
Yes. A foreign will can be accepted by the Thai court once it is translated and legalised. The court must also be satisfied that the will is valid under the law of the country where it was made.
Validation is not automatic. The court may request evidence, witness statements or additional documents. Families often choose to prepare a simple Thai will for assets located in Thailand to reduce complexity and avoid delays.
Joint account holders do not usually receive automatic access. Most banks freeze the account until the court appoints an administrator.
Some joint accounts operate on an ‘either to sign’ basis and may allow access once the death certificate is provided, although this is uncommon. Thai law does not recognise survivorship rights in the same way that some countries do. Probate often remains necessary for joint accounts, particularly for larger balances.
Some banks allow small balances to be released without probate, although the threshold varies. This can range between THB 50,000 and 200,000.
This exemption is not guaranteed and depends on internal bank policy. Heirs normally need to provide the Thai death certificate and proof of their relationship. Anything above the bank’s threshold requires a full probate case. Your representative can check each bank’s eligibility rules.
A spouse, adult child, parent, sibling or executor named in a will can apply. The court decides who is most suitable if more than one person requests the role.
Applicants must be at least twenty years old, of sound mind and not bankrupt. Same-sex spouses have full inheritance and probate rights since January 2025. A person overseas can apply and then appoint a representative to act for them in Thailand.
The administrator has legal authority to collect assets, close accounts, manage property and distribute the estate. They are responsible for acting honestly and in the best interests of the estate.
Once appointed, the administrator can request information from banks, obtain statements, deal with the land office, settle debts and arrange the final distribution. They may also need to provide a final accounting if requested by the court. Failure to perform these duties properly can result in personal liability.
Yes. Thai law recognises same-sex marriages for probate and inheritance purposes. Same-sex spouses have equal rights to apply for probate and receive their lawful share of an estate.
This followed amendments to the Civil and Commercial Code which came into effect on 23 January 2025. Same-sex spouses are now treated the same as opposite-sex spouses when probate is granted.
You are strongly advised to instruct a lawyer. Probate is a legal process that involves the court, official translations, legalisations and strict procedural requirements.
A lawyer ensures all documents are complete, prepares the probate petition, manages court filings and supports your representative at the hearing. Errors in preparation or incomplete powers of attorney can lead to significant delays. Most families overseas rely on legal support to complete the process efficiently.
Yes. A representative can complete the entire probate process for you. You do not need to attend any hearings.
Once appointed through a legalised power of attorney, your representative can gather documents, work with the lawyer, attend the court hearing and collect the probate order. They also help with banks, property, vehicles and final asset transfers. This approach is common for families based overseas.
The administrator can begin managing the estate. Banks and authorities require sight of the court order before they release assets.
The administrator requests statements, closes accounts, transfers funds, deals with property and settles any debts. Once administration is complete, the assets are distributed to the heirs named in the will or under Thai intestacy rules. The administrator may need to provide an update or final accounting to the court.
Costs vary according to the complexity of the estate. Most involve court fees, translations, legalisations and legal support.
Translations normally cost between THB 800 and 1,050 per page. Court filing fees are modest, although publication fees for creditor notices may apply. Legal fees for a typical probate case often range between THB 50,000 and 200,000. Estates can usually cover these costs once an administrator is appointed.
