Certificate of bachelorhood/single-status/eligibility to get married can be issued by a competent court having jurisdiction of the area of the residential address of the applicant. This can be in the form of a declaratory order for which a suit has to be filed before the appropriate court for the specific purpose which is required to be counter-attested by the Home Department of the State concerned. Thereafter, it is to be attested/apostilled by the Attestation Section of the Consular, Passport & Visa (CPV) Division of the Ministry of External Affairs, New Delhi.

Each state of the country has its own rules in this regard, hence specify.

1. It may not be true that without the affidavit from his parents, he won't get his single status certificate for his marriage.

2. The Indian Consulate in Thailand shall have to issue the matrimonial status certificate for him on his submission of an affidavit from him affirming that he is single.

An affidavit can be made by your husband in India stating this very fact that he is single. It should be notarized and should be registered with registrar.

That would be sufficient so as to prove that he is single.

In India we dint require a certificate that one is single. A person has to declare that he is single in the marriage certificate itself and that us necessary as a person speaking lies under oath shall be punished.
