The Declaration of No Legal Impediment to Marriage is a statutory declaration where both parties confirm that there is no legal reason they cannot marry each other. It is a serious legal document — not just procedural paperwork.

What does it confirm?

By signing, both parties verify that they are not currently married to someone else, that they are at least 18 years old, and that they are not in a prohibited relationship.

When is it signed?

The declaration is typically completed near the wedding date — often during the rehearsal or just before the ceremony begins. Your celebrant will prepare and explain the document, and it must be signed in their presence.

Why does it matter?

It serves as a final check to confirm there are no legal obstacles to the marriage. Your celebrant cannot legally proceed with the ceremony without this completed declaration.

Providing false information on this declaration is a legal offence in Australia, making it a serious undertaking for both parties.
