Hi Everyone, it's Kristy from Clearly Legal.
I wanted to chat with you today about disability, as defined by the Rules of Civil Procedure.
Disability plays a crucial role in civil litigation under Ontario's Rules of Civil Procedure, because it creates limitations and extra consideration that all parties need to be aware of and work with.
What Disability Means Under Ontario's Rules of Civil Procedure
In Ontario, the term disability has a specific legal meaning within civil procedure. It refers to individuals who cannot fully participate in legal proceedings. The Rules of Civil Procedure identify three groups under this definition:
Minors: Persons under the age of 18
Mentally Incapable Persons: Those who lack the mental capacity to make decisions, as defined by the Substitute Decisions Act
Absentees: Individuals who have disappeared and whose whereabouts are unknown, as defined by the Absentee Act
Each category has distinct legal considerations that affect how you approach litigation involving these parties.
Minors and Their Legal Representation
A minor is anyone under 18 years old. The law recognizes that minors cannot represent themselves in court. Instead, a litigation guardian must be appointed at the commencement of litigation (or via motion) act on their behalf. This protects the minor’s interests and ensures fair legal proceedings.
As a by the way, section 2 of the Substitute Decision Act recognizes that people 18 or older are capable of entering into a contract
Mentally Incapable Persons and the Substitute Decisions Act
The Substitute Decisions Act defines a mentally incapable person as someone who cannot understand information relevant to making a decision or cannot appreciate the reasonably foreseeable consequences of a decision or lack of decision.
It is entirely that the party possible meeting this portion of the definition will need to be assessed for capacity in order for this declaration to be made. It is entirely possibly this declaration will be needed after the commencement of the litigation and be managed in motion format.
Section 20.1 of the Substitute Decisions Act discusses assessing for capacity.
Absentees and the Absentee Act
An absentee is a person who has disappeared and whose whereabouts are unknown, this includes the question of the person is alive. The Absentee Act provides a legal framework for managing the property and interests of absentees during their absence.
Section 4 of the Absentee Act discusses the appointment of a committee for this purpose, and this committee essentially becomes guardian as per the Substitute Decisions Act.
Motion for Capacity, Motion for Appointment of Litigation Guardian.
When litigation involves any part of the definition of Disability, it also often involves doctors, assessments and motions. I have managed all aspects of these proceedings (I will be real and call them delays...because when disability is not realized or considered at the beginning of litigation, delay is what it is). Much of these delays are procedural organization, scheduling and motion work that clerks can do.
All of this is work I can do and offer. Contact me at kristy@clearlylegal.ca and we'll chat.
