Please ensure that documents relating to notarial services you require from the Department of Foreign Affairs Northern Territory Office are presented in the correct form and that you provide the correct instructions for witnessing any signatures on the documents. If you are unsure of the legislative requirements relating to witnessing signatures on a particular document, you should seek independent legal advice. Please note, by witnessing a signature on a document neither the Australian Government nor the Northern Territory Office guarantees the legal effectiveness of the document or the accuracy of its contents.
Overseas governments sometimes need proof that Australian documents are genuine before they will accept them. Please confirm requirements with the Embassy or Consulate of the country you are submitting the documents to. The Department of Foreign Affairs and Trade will certify that official signatures, stamps or seals on a document are genuine by checking them against a specimen held on file, and stamping the document with an Authentication or Apostille.
In most cases, documents can be processed in three business days. There may be a delay if we do not have a specimen signature on file of the person who has signed your document (this means we will need to verify their signature), or at peak times (such as during university graduation periods).
Documents requiring an Authentication or an Apostille can be lodged between 8.30am and 12.00pm Monday to Friday. Alternatively, documents can be submitted by post.
Certificates of No Impediment
The Department of Foreign Affairs and Trade cannot advise on the specific requirements that may need to be met in order for a marriage to be legal in a particular country.

If accepted by the foreign authorities, Certificates of No Impediment for marriage overseas (CNIs) can be issued by our office in person for citizens and permanent residents of Australia.
