N.D. Cent. Code § 21-03-39: Ancillary contract authorized

After any municipality has provided, as required by section 21-03-16, for an issue of bonds for a lawful purpose which can be accomplished only through performance of an executory contract by some other contracting party, such contract may be entered into before the actual execution or sale of the bonds with like effect as if the necessary cash for payments on the contract already were in the treasury.
