Frequently asked questions

Notarisation and legalisation questions.

What is the difference between notarisation and legalisation?
Notarisation generally involves certification by a Thai Notarial Services Attorney, such as witnessing a signature or certifying a true copy. Legalisation is a separate authentication process that may involve the Thai Ministry of Foreign Affairs and the embassy or consulate of the country where the document will be used.
Do I need to appear in person?
If your signature must be witnessed, you will generally need to sign in the presence of the Notarial Services Attorney. Certified-copy or legalisation requirements may differ. Corporly will confirm the attendance requirements after reviewing the document.
Should I sign the document before submitting it?
Do not sign a document requiring witnessed signature notarisation until you have received signing instructions. You may upload an unsigned copy for initial review.
What documents can be notarised?
Common requests include powers of attorney, affidavits, declarations, consent letters, contracts, passports, identification documents and corporate records. Whether a particular certification is appropriate depends on the receiving organisation's requirements.
Does notarisation automatically make a document valid overseas?
No. The receiving country or organisation may require additional legalisation, embassy authentication, translation or other formalities. Corporly will confirm the proposed process after reviewing the intended use.
Can Corporly provide an immediate quotation?
The scope and fee depend on the number and type of documents, whether a signature must be witnessed, the destination country and whether Thai MFA or embassy legalisation is required. Corporly will provide a scope and quotation after the initial review.
