Complete Form 18 without retyping your details

Form 18 under the Substitute Decisions Act is an application to the Consent and Capacity Board — and it repeats the names and addresses of the people involved. This guide is an example of storing them once in hivi.

Official form and source

Start from the official form and always use the current version — form numbers and links can change.

There is no single ontario.ca page that walks through filing this application. The form goes to the Consent and Capacity Board (not ServiceOntario). For background on capacity findings and the Board, see Mental capacity — ontario.ca.

What this form is about

Form 18 is the application to the Consent and Capacity Board to review a finding that someone is incapable of managing property (Substitute Decisions Act, subsection 20.2(1)). It is not a guardianship application and not a power-of-attorney form — it challenges an existing incapacity finding.

Before you start: what to gather

• Your full legal name and contact details.
• The name and details of the person the application concerns.
• Supporting documents (confirm on ontario.ca).

How hivi makes it faster

1. Save it once. Store your name, address, and contact details in your hivi profile.
2. Keep documents ready. Upload supporting documents to hivi Files so you are not searching at form time.
3. Autofill the form. Use the hivi Chrome extension on a web form, or fill a PDF from your saved profile inside hivi.
4. Review and submit yourself to the Consent and Capacity Board.

Why do it in hivi

Capacity and board-review forms repeat the same personal details. Captured once in hivi — stored in Canada, with AI on its own servers — every form starts mostly complete.
