parties
Parties are the people or organizations directly involved in a court case, contract, agreement, or other legal matter. For example, a party can be one person, a group of 2 or more people, a corporation, or a government organization like a municipal subsidized housing provider.
In most housing law cases, the landlord and the tenant are parties. The minor children of the tenant are usually not parties. Other examples of parties include former landlords, employees of the landlord, or buyers of the home.
