Neb. Rev. Stat. §§ 11-115
If any person elected or appointed to any office neglects to have his or her official bond executed and approved as provided by law and filed for record within the time limited by sections 11-101 to 11-122, the officer with whom the bond is required to be filed shall immediately issue an order to such person to show cause why he or she has failed to properly file such bond and why his or her office should not be declared vacant. If such person properly files the official bond within ten days of the issuance of the show cause order for appointed officials or before the date for taking office for elected officials, such filing shall be deemed to be in compliance with sections 11-101 to 11-122. If such person does not file the bond within ten days of the issuance of such order for appointed officials or before the date for taking office for elected officials and sufficient cause is not shown within that time, his or her office shall thereupon ipso facto become vacant, and such vacancy shall thereupon immediately be filled by election or appointment as the law may direct in other cases of vacancy in the same office. This section does not apply to county officers covered pursuant to subdivision (22) of section 11-119.
