In legal cases, a litigation friend is someone who is appointed to represent an individual who is unable to conduct legal proceedings themselves due to a lack of capacity. This is typically seen in cases where the person in question is a minor, mentally incapacitated, or in any other way unable to represent their own interests in court.
The role of a litigation friend is to make decisions and take actions on behalf of the person they are representing to ensure that their best interests are upheld throughout the legal process. The appointment of a litigation friend can vary depending on the jurisdiction and specific circumstances of the case, but it is generally done to safeguard the rights of vulnerable individuals who may not be able to make legal decisions for themselves.
