Thai Wills, Probate and Cross-Border Estate Administration

Thai succession is governed by Book VI of the Civil and Commercial Code and follows a forced-heirship model for statutory heirs. Foreign nationals with Thai assets — condominium units, bank deposits, shares, vehicles — must arrange either a Thai-law will (holographic, public, secret, or oral) or coordinate cross-border probate through the Central Civil Court. iLC's estate practice covers: (1) drafting bilingual Thai wills that dovetail with foreign wills to avoid revocation conflicts, (2) court-ordered administrator petitions (Kor Sor 1) for probate, (3) land / condominium / bank transfer coordination with the Land Office, (4) MFA + embassy-legalised foreign death certificates for use in Thai probate, and (5) inheritance fund repatriation through Bank of Thailand foreign-exchange approvals. Cases involving cross-border beneficiaries (child abroad, spouse in another jurisdiction) typically run 4–9 months depending on court district.

End-to-End Process — will estate probate

The workflow below reflects current 2025–2026 practice with the relevant Thai authority and factors in queue seasonality, translation dependencies, and cross-agency handoffs.

  1. 1) Estate map

    Inventory of Thai and foreign assets with valuation and legal-title status.

  2. 2) Will drafting or review

    Bilingual Thai-law will drafted and coordinated with any foreign will to eliminate conflict clauses.

  3. 3) Court petition (probate)

    Kor Sor 1 petition filed at the Civil Court where the deceased was domiciled.

  4. 4) Administrator appointment

    Court issues the administrator letter within 30–90 days depending on opposition.

  5. 5) Asset transfers

    Land Office title transfers, condominium transfers, bank fund releases, and share re-registrations.

  6. 6) Repatriation and reporting

    Foreign-exchange approvals and tax reporting to Revenue Department completed.

In-Depth FAQ

Can a foreign will govern Thai assets?

Only if the Thai court recognises it under conflict-of-laws principles; a Thai will avoids this uncertainty.

Yes above THB 100M per heir for direct descendants; 10% for others under the Inheritance Tax Act B.E. 2558.

Can a foreigner inherit Thai land?

Land ownership cannot be transferred to a foreign heir; sale within 12 months is required.

Do we need Thai lawyers for probate?

Yes; only Thai-licensed lawyers may appear before Thai courts.
