Notarised will-related and cross-border estate documents

Thai law prescribes several statutory forms of will, including the ordinary written will with two witnesses, the entirely handwritten will, and the will made as a public document before a district officer. Notarisation does not change the statutory form and cannot cure a will that fails it; it supports the use of related documents before foreign courts and banks — for example witnessing signatures of the testator and witnesses, or certifying copies of asset records. Where assets sit in several jurisdictions we recommend parallel advice from a succession lawyer.

Frequently asked questions

Can a Notarial Services Attorney appoint an estate administrator?

No. In Thailand an administrator is appointed by court petition. Certification only covers signatures and copies used in the process.

Is a will valid if signed before the attorney?

Validity depends on the statutory form, such as witnesses and method. A signature certificate does not by itself make a will valid.

Assets are in several countries. What is needed?

Each country has its own estate process. Check with a lawyer or authority in each country which Thai documents and form they require.

When is notarised will-related and cross-border estate documents used and what do I receive?
