Real Thailand legalization cases

Illustrative examples based on common situations; names and details are changed.

IE
Indian Expat, Hong Kong

from India to France

Apostille
The problem was…

An Indian expat living in Hong Kong had their Indian birth certificate notarized and apostilled by Hong Kong authorities, but France rejected it.

We solved it…

Documents can only be apostilled by the competent authority of the country that originally issued them. The applicant had to restart the process in India.

Result

In this example, the application was resubmitted with the correct apostille from India — the issuing country's competent authority.

CA
California Applicant

from USA to International

Apostille
The problem was…

A private affidavit notarized by a California notary was rejected for a state apostille because the notary stamped their seal on a blank white space instead of over the printed text of the affidavit.

We solved it…

The applicant had to reprint a fresh original of the private affidavit and ensure the notary followed state-specific seal placement guidelines perfectly before resubmitting.

Result

In this example, the document was resubmitted with the correct notary seal placement for the state office to review.

WS
Wrong State Apostille

from USA to Mexico

Apostille
The problem was…

A user paid a third-party service for a California birth certificate apostille, but received a Kansas apostille attached by a proxy notary, which was rejected in Mexico.

We solved it…

The applicant had to dispute the credit card charge and apply properly directly through the California Secretary of State.

Result

In this example, the fix is to dispute the third-party charge and apply directly through the California Secretary of State.
