What is a Single Status Affidavit and what is it used for?
Notarised single-status declaration for marriage abroad. A Thai Notary Public, working under the Lawyers Council of Thailand, certifies the document so it can move on to MFA legalisation and embassy legalisation for use abroad — the legal weight is equivalent to notarisation in other jurisdictions once the chain is complete.
