Minn. Stat. § 16A.41: CLAIMS AGAINST STATE.

Subdivision 1. Certified.

Except as provided in subdivision 1a, when claims against the state are made for which there is an appropriation available, an official with authority to pay a claim shall approve the claim by certifying that the service was performed, the goods or material furnished, or monthly telephone service is in effect. The claim must be sent to the commissioner accompanied by a transmittal form as prescribed by the commissioner.

Subd. 1a. Exception to certification.

When a claim against the state is made by a county, municipality, or other governmental subdivision, under an agreement with the commissioner of transportation, and that agreement provides for payment of the state's contractual obligations before commencing the work, certification that the services have been performed or that the goods or materials have been furnished is not required as a prerequisite to payment of the claim.

Subd. 2. Declaration.

The commissioner may require a claimant to declare that the claim and its amount are just and correct and that no part of it has been paid. The following form may be used:

"I declare under the penalties of perjury that this claim is just and correct and that no part of it has been paid.

Signature of Claimant."

Subd. 3. Declaration same as oath.

To sign the declaration in subdivision 2 is the same as to sign and swear under oath.
