What are intervenors?

An intervenor is another party that intervenes in a case. For example, say a married couple are divorcing and one of the parties is in a partnership with another person. That other person finds that the business will be affected by the divorce, and they then ask the court’s permission to be included in the matter which affects only them. Thus, they intervene. If there is more than one party, then these parties are called intervenors.
