Deannexation is the removal of an area from the boundaries of a municipality. It is the reverse of annexation, but is not limited to formerly annexed territory: even portions of a municipality's original territory may be deannexed. Deannexation may also apply to other local government entities, such as school districts.[1]
Other terms for deannexation include disannexation, secession, detachment,[2] disconnection,[3] severance[4] and exclusion.[4] Deannexation for the purpose of creating a new municipality is sometimes called division.[5]
The procedures and requirements for deannexation vary greatly among the states. Most states provide for some sort of deannexation procedure, and a majority of those states also allow residents to petition for deannexation. Many states specifically require some sort of judicial or administrative agency review of deannexation petitions.[6]
Deannexations are much less common than annexations. When they occur, they are typically small-scale and involve individual properties; deannexations of entire neighborhoods are unusual.
