A statutory declaration (stat dec) can be witnessed by an authorized person depending on the jurisdiction. Generally, such witnesses include:

• Justice of the Peace (JP)
• Commissioner for Declarations (Cdec)
• Notary public
• Lawyer or legal practitioner

• Senior police officers (in some jurisdictions)

The exact list of authorized witnesses varies by region and may include various professionals like architects, chiropractors, dentists, or government officers depending on local laws.
