••• Court image by Yuriy Rozanov from

Contact the Ministry of the Attorney General Capacity Assessment Office and request a list of active capacity assessors in your area.

Make appointments to interview a few assessors. You are responsible for contacting and contracting with a capacity assessor. According to the Capacity Assessment Office, charges range from $70 to $150 per hour, as of January 2011.

Interview the assessors. Bring any documentation you consider relevant, including notarized statements from witnesses to instances of mental incapacity on the part of the person involved. If you know the subject will refuse to be assessed, discuss how to arrange a covert assessment.

Retain the services of your chosen assessor and follow any instructions regarding the staging of the assessment. Following the assessment, the assessor will submit findings to you and to the Ministry. If the assessor recommends a competency hearing, you will be notified when it is put on a docket.

Attend the hearing. If a finding of incompetency results, guardianship will go to the person holding the most recent power of attorney (POA) executed when the subject was still competent. If no POA exists, the court will appoint a Guardian of Property.

If you wish to be appointed the subject's Guardian of Property, you must apply to the Superior Court of Justice. The details of what to include in the application are contained in the Substitute Decisions Act. The application may be made and submitted before the final decision on competency has been determined.
