Neb. Rev. Stat. § 81-138.02: Contracts; not valid encumbrances; exception.

Contracts, other than a purchase order, for goods or services to be provided in a subsequent biennium do not represent valid encumbrances of current biennium appropriations and will require specific reappropriation by the Legislature. Only that portion of a contract which meets the criteria established in subdivision (2) of section 81-138.01 may be encumbered.
