Texas National Medical Support Notice Note (MSN) is a form sent to employers of noncustodial parents who are ordered to provide health insurance coverage for their children. The form informs the employer of the legal obligation to provide health insurance coverage and informs the employer which employee is responsible for providing the coverage. There are two types of Texas MSN: Original Notice and Enforcement Notice. The Original Notice is sent to the noncustodial parent’s employer to inform them of the obligation to provide health insurance coverage. The Enforcement Notice is sent to the employer when the noncustodial parent has failed to provide health insurance coverage and the state is enforcing the court order. The Enforcement Notice will include the employer’s obligation to provide coverage and will also include an administrative wage garnishment.
