Definitions

In New Mexico, there are two types of water litigation:

  1. Civil Water (non-adjudication) cases, which are disputes over usage under a previously determined scope of rights. See the Civil Water Law (non-adjudication) Cases section and;
  2. Water Rights Adjudication cases, which involve a system-wide declaration of water rights in a basin. See the Water Rights Adjudication section.

Civil Water (non-adjudication) Cases

Civil Water (non-adjudication) cases involve disputes between parties over usage under a previously determined scope of rights. 

Beginning on October 1, 2025, filing attorneys for water law cases will follow Supreme Court Provisional Order #S-1-AO-2025-00017.


Water Rights Adjudication

No changes have been made to the processing of water adjudication cases.

Water rights adjudications involve a system-wide declaration of water rights in a basin.  They determine who owns which water rights and in what amount, and are required by law.
