Neb. Rev. Stat. § 25-1237

(1) When authorized by rules promulgated by the Supreme Court, the clerk of the district court may issue a subpoena for discovery in Nebraska for a civil proceeding pending in a foreign jurisdiction. Such a subpoena may command a person to testify at a deposition or command a nonparty to provide discovery without a deposition. (2) The Supreme Court may promulgate rules for subpoenas under this section. The rules may specify the amount of a fee, if any, that must be paid to the clerk of the district court for the issuance of such subpoenas. Any such rules shall not conflict with laws governing such matters.
