Constables have served Arizona since the inception of the territory in 1863. Constables are the elected peace officers of the justice precinct, and have the same powers, duties and liabilities as sheriffs, as far as applicable. Constables are elected to 4-year terms in their precinct, and serve all papers, processes, writs and warrants from their justice courts and any competent authority.

Constables conduct asset seizures to fulfill court judgments, conduct evictions, serve protective orders, summonses, subpoenas, and both civil and criminal arrest warrants. Constables who are elected by voters within their judicial precincts are able to provide timely and cost efficient service by working directly with the courts in their local communities to ensure the court's orders are served.

The Arizona Constables Association serves its members by offering professional training to enable them to perform their duties. The Association holds a minimum of two training seminars per year at which time training and updates are provided that comply with requirements mandated by state law.
