21.10 Interstate agreements32
A state may have a written agreement with another state setting forth rules and procedures resolving cases of disputed residency. These agreements may establish criteria other than those specified in §§ 21.07 and 21.08, but must not include criteria that result in loss of residency in both states or that are prohibited by § 21.09. The agreements must contain a procedure for providing health benefits to individuals pending resolution of the case. States may use interstate agreements for purposes other than cases of disputed residency to facilitate administration of the program, and to facilitate the placement and adoption of a Title IV-E individual when the child and his or her adoptive parent(s) move into another state.
