No forced heirship -- Thailand's statutory intestate-succession system
Unlike the civil-law forced-heirship regimes this platform describes for France, Italy, Spain,
Portugal, and elsewhere, Thailand does NOT impose a fixed mandatory percentage that must go to specific
heirs regardless of a will's terms. Instead, in the absence of a valid will, Section 1629 of the Thai
Civil and Commercial Code applies a statutory intestate-succession system with six classes of heirs, with
higher classes excluding lower ones, and a surviving spouse inheriting alongside statutory heirs after
division of marital property. A foreign will can be legally recognized in Thailand under the Conflict of
Laws Act, but enforcement is complex given legalization and translation requirements, and Thai legal
practitioners commonly recommend executing a separate, localized Thai will covering Thai-situs assets
specifically, to simplify probate and avoid delay.
Mandatory probate, and an open question for foreign heirs inheriting land
Probate is mandatory in Thailand for transferring registered assets such as land, condominium units,
or company shares -- a Thai court must appoint an estate administrator before such assets can be
transferred, regardless of the deceased's nationality. This platform could not independently verify the
specific rules governing a foreign heir's ability to inherit Thai land outright, since Thai property law
generally restricts foreign land ownership, and flags this as an area needing separate, deeper
confirmation for anyone inheriting Thai real estate specifically -- do not assume a foreign heir
automatically receives the same land-ownership rights a Thai heir would.
Thailand's inheritance tax, in effect since 2016
Thailand introduced an Inheritance Tax Act, effective 1 February 2016. A THB 100 million
per-beneficiary exemption threshold applies to the net value of inherited assets, with tax charged only on
the amount above that threshold: 5% for direct descendants and ascendants (children, parents,
grandparents), and 10% for all other beneficiaries. Lawful spouses are fully exempt regardless of value.
This tax applies to foreign nationals and non-residents inheriting Thai-situs assets above the threshold --
nationality confers no exemption. A 150-day compliance deadline runs from receipt of the inheritance, with
penalties up to a 100% surcharge and potential criminal fines for late filing. Separately, whatever the
deceased owned in India is governed by Indian succession law and procedure -- typically a Succession
Certificate, Letters of Administration, or Probate from the relevant Indian court.
Common mistakes NRIs and Indian-origin families connected to Thailand make with succession matters:
- Assuming Thailand has forced-heirship rules similar to France, Italy, Spain, or Portugal, when it
instead uses a statutory intestate-succession system that only applies without a valid will.
- Relying solely on an Indian will for Thai-situs assets, rather than executing a separate,
localized Thai will as commonly recommended.
- Missing the 150-day inheritance-tax compliance deadline, which carries steep penalties for late
filing.
