End-to-end preparation, attestation, and notarization of the statutory Estate Inventory that every administrat
Notarial Inventory of Estate · CCC §§ 1728–1732 · Inheritance Tax Act 2558 · HCCH (in force for Thailand 28 February 2027)
End-to-end preparation, attestation, and notarization of the statutory Estate Inventory that every administrator must file with the Thai court within 15 days of appointment under CCC § 1728. Covers real estate (land titles, condominiums), bank accounts and FCDs, listed and unlisted equity, intellectual property, vehicles, art and collectibles, digital assets / crypto, offshore accounts, life insurance, provident funds, family businesses, and liabilities. Drafting + notarization with 2 witnesses + court filing + MFA Apostille for overseas probate (US Form 706-NA, UK IHT400, EU EUCS, AU Probate, JP/KR/SG). Fixed-fee only — no contingency on estate value (Lawyers Council Ethics § 11).
A Notarial Inventory of Estate is the asset schedule that an administrator (or executor) must produce within 15 days of court appointment under CCC § 1728. It must be signed before at least two witnesses under § 1729 and serves as (a) evidence to the court and creditors that the administrator has identified the full estate; (b) the basis for inheritance tax under the Inheritance Tax Act B.E. 2558 (estates above THB 100M per heir); (c) the supporting document for overseas probate authorities (US Probate Court / IRS Form 706-NA, UK Probate Service / HMRC IHT400, Schengen EUCS, etc.).
Key cross-border issues for foreigners: (1) Estate situs — Thai courts have jurisdiction only over assets located in Thailand; overseas assets need ancillary probate in their home jurisdiction. (2) Foreign Will recognition — a foreign will is valid in Thailand only if it complies with CCC §§ 1655–1672 form requirements. (3) Condominium 49% quota — if estate condos plus the foreign heir's share push the building above 49% foreign ownership, the heir must dispose within one year under Condominium Act § 19/2. (4) Land quota — foreign heirs may receive land only to sell within one year under Land Code § 93. (5) FCDs and offshore accounts require coordination with BOT Form Tor.Tor.3 and overseas banks.
Common failure modes: (1) Concealment of known assets — aggravated embezzlement by fiduciary under Penal Code § 354 (6 months to 7 years + loss of inheritance under CCC § 1606); (2) Mis-valuation — under-states inheritance tax and distorts heirs' shares; heirs may sue under § 1722; (3) Skipping the 2-witness rule — inventory void under § 1729, administrator removable under § 1727; (4) Filing beyond 15 days — grounds for removal; (5) Omitting overseas assets — exposes the estate to IRS/HMRC disclosure penalties up to 50% of asset value; (6) Skipping digital assets / crypto — irrecoverable loss if private keys are lost.
Our process: (1) review the court order + will (if any) + any foreign will; (2) asset discovery — Land Department, DBD, SEC, DSI crypto registry, all Thai banks (under BOT Authorization Letter), insurance offices, DIP IP registry; (3) valuation — Land Department appraisal, fund NAV, equity closing price, date-of-death FX mid-rate, independent appraisal for art/IP/crypto; (4) drafting in Thai-court format + US/UK/EU/AU format for Apostille; (5) signing before attorney + 2 witnesses + Jurat; (6) court filing within 15 days; (7) MFA Apostille + sworn translation + ancillary probate; (8) inheritance-tax filing (Form M.60 within 150 days) where applicable; (9) PDPA-compliant encrypted asset register; (10) fixed-fee only — never a percentage of estate value (Ethics § 11).

PDPA + AMLA + Inheritance Tax — compliance included
When must a foreign administrator prepare the inventory?
Within **15 days** of court appointment under CCC § 1728. Missing the deadline lets heirs petition for removal under § 1727 and the court may order damages under § 1722. Complex estates may apply for an extension with reasons.
How many witnesses must sign the inventory?
The administrator must sign **before at least 2 witnesses** under CCC § 1729 + a Notarial Services Attorney attests the signature under Reg. 2546 §§ 20–22 + a Jurat is administered under §§ 17–19. Fewer than 2 witnesses → inventory void → court will remove the administrator.
What happens if assets are concealed from the inventory?
Aggravated embezzlement by a fiduciary under **Penal Code § 354** — 6 months to 7 years' imprisonment + fine + **loss of inheritance rights** under CCC § 1606 (unworthy heir) + co-heirs may sue for damages under § 1722.
Must overseas assets appear in the Thai inventory?
**Yes** if the deceased was a Thai national or resident in Thailand (CCC § 1599) — use the date-of-death FX mid-rate. Thai courts have no jurisdiction to administer overseas assets; ancillary probate in each jurisdiction is required. We coordinate with probate lawyers in 30+ countries through INSOL/UIA networks.
How is crypto handled in the inventory?
(1) Wallet address + blockchain (BTC/ETH/SOL/etc.); (2) coin quantity + USD value at date of death (CoinMarketCap / Bloomberg); (3) custody plan — private-key holder, hardware wallet, multi-sig threshold; (4) if held on an exchange (Binance TH, Bitkub) request the account statement; (5) tax treatment per RD Notification 2566. Omitting crypto risks tax penalties + permanent loss of assets.
What does a Notarial Inventory cost?
Fixed-fee by complexity: (1) basic < 10 line items = quote on request (phone / LINE / email); (2) standard 10–30 items + 1 jurisdiction = quoted on request; (3) complex multi-jurisdiction + crypto + IP = quoted on request; (4) MFA Apostille = quoted on request; (5) sworn translation = quoted on request. **Never a percentage of estate value** (Ethics § 11).
Can a foreign heir inherit land in Thailand?
Under Land Code § 93, foreign heirs may take title **only to sell within one year**. For condominiums under Condominium Act § 19, foreign heirs hold full title provided the building remains within the 49% foreign quota; otherwise they must dispose within one year under § 19/2. We prepare an Asset Disposal Plan alongside the inventory.
How is inheritance tax calculated?
Inheritance Tax Act B.E. 2558: (1) only estates **> THB 100M per heir**; (2) **5%** for ascendants/descendants, **10%** for others; (3) Form **M.60** filed within **150 days** of receipt; (4) included: real estate, securities, bank deposits, registered vehicles; (5) excluded: life insurance proceeds, personal effects, donations to state/temple. We calculate and file.
Where can an apostilled inventory be used?
Since 28 February 2027, Thailand is an HCCH contracting state → a single MFA Apostille is valid in **127 contracting countries** including US, UK, EU, AU, NZ, JP, KR, SG, HK, CN (incl. Macau). Countries still requiring embassy legalization: UAE, Saudi Arabia, Qatar, Vietnam, Indonesia, Myanmar, Iran.
Assets exist in Thailand and abroad — where do I open probate?
**Concurrent probate** — Principal probate in the deceased's domicile (e.g. UK Probate Service) + **ancillary probate in Thailand** for Thai-situs assets (CCC § 1599). We draft 2 inventories: (1) a Thai inventory for the Thai court; (2) a worldwide inventory for principal probate + Apostille. We coordinate cross-border probate counsel in 30+ countries.
How does PDPA affect the inventory?
Inventories contain financial and health data (cause of death) about the deceased and heirs — sensitive data under PDPA § 26. We issue a privacy notice, store encrypted, share only with statutorily-required authorities, and honour data-subject deletion within 30 days (subject to the 10-year statutory retention under CCC § 1754).
Why not charge a percentage of estate value?
Lawyers Council Ethics § 11 prohibits Thai lawyers from contingency fees, and percentage fees create a serious **conflict of interest** (incentive to over-value or favour certain heirs). We invoice fixed fees, quoted in writing before work begins.

Short answer: In Thailand the certifying officer is a lawyer registered as a Notarial Services Attorney with the Lawyers Council. The signer must sign in front of that lawyer with original identity documents. The certificate is then authenticated at the Department of Consular Affairs and at the receiving country's embassy where required.

Foreign nationals
1. Confirm the receiver's requirements before printing
Establish which act is needed (signature witnessing, affirmation or certified copy), whether fixed wording applies, and how many authentication layers the receiver expects.
⏱ Same day
2. Assemble documents and book the signing
Complete the set, print the final text and leave the signature block blank, because signing must happen in the attorney's presence.
⏱ 1 working day (estimate)
3. Sign before the attorney and obtain the certificate
The attorney verifies identity, checks the document, records the act in the register, then signs and seals the certificate.
⏱ 1 working day (estimate)
4. Authenticate at the Department of Consular Affairs
Submit the certificate to the Legalization Division so the attorney's signature is authenticated, where the receiver requires that layer.
⏱ 2-5 working days (estimate, excluding agency queues)
5. Embassy authentication and delivery
File with the receiving country's embassy or consulate under its own procedure, then deliver the sealed set without breaking the cross-seal.
⏱ 3-10 working days (estimate, varies by mission)

Document and legalization advisers with 15+ years of practice
Before we start, we read your actual documents and confirm the legalization route matches what the receiving authority asks for. During the work we report progress, and after delivery we still answer questions about how to submit the file.
We prepare documents to the requirements of the receiving authority. Any approval decision remains at that authority's discretion.
Send your documents on LINE for a preliminary review, a recommended legalization route and a written quote.
General guidance, not a case-specific determination. Requirements change with agency notices — confirm with the receiving authority before you act.

Estate planning + probate packages frequently bundled together
Short answer: The most frequent causes are signing before meeting the attorney, expired identity documents, choosing a certificate type the recipient does not accept, and skipping a step in the legalisation chain. Each is fixed by re-executing a correctly drafted certificate before the next certification round starts.
If a second round is not an option, our advisers review the recipient's form, select the correct instrument and map the full chain before you start — send us the documents for a pre-check.
