Nev. Rev. Stat. § 31.249

1. No writ of garnishment in aid of attachment may issue except on order of the court. The court may order the writ of garnishment to be issued: (a) In the order directing the clerk to issue a writ of attachment; or (b) If the writ of attachment has previously issued without notice to the defendant and the defendant has not appeared in the action, by a separate order without notice to the defendant.

2. The plaintiff's application to the court for an order directing the issuance of a writ of garnishment must be by affidavit made by or on behalf of the plaintiff to the effect that the affiant is informed and believes that the named garnishee: (a) Is the employer of the defendant; or (b) Is indebted to or has property in the garnishee’s possession or under the garnishee’s control belonging to the defendant, and that to the best of the knowledge and belief of the affiant, the defendant's future wages, the garnishee's indebtedness or the property possessed is not by law exempt from execution. If the named garnishee is the State of Nevada, the writ of garnishment must be served upon the State Controller.

3. The affidavit by or on behalf of the plaintiff may be contained in the application for the order directing the writ of attachment to issue or may be filed and submitted to the court separately thereafter.

4. Except as otherwise provided in this section, the grounds and procedure for a writ of garnishment are identical to those for a writ of attachment.

5. If the named garnishee is the subject of more than one writ of garnishment regarding the defendant, the court shall determine the priority and method of satisfying the claims, except that any writ of garnishment to satisfy a judgment for the collection of child support must be given first priority.
