Witnessing Documents

On 1 January 2006 the Parliament of Western Australia proclaimed the Oaths, Affidavits and Statutory Declarations Act 2005 which made changes to the manner in which oaths, affidavits and statutory declarations are administered and witnessed.

Under the new legislation more than 40 occupational groups are able to witness statutory declarations, including teachers, engineers, doctors and public servants. This change means the role of commissioner for declarations no longer exists.

Affidavits (including Family Court documents) can only be witnessed by a justice of the peace, lawyer or public notary.

The Department of the Attorney General would like to thank all former commissioners for declarations for the long-standing service they have provided to the Western Australian community.

Professions that can now witness statutory declarations include:

  • Academic {post-secondary institution}
