The Minnesota Affidavit of Increased Costs is a legal document used by people in the state of Minnesota when they intend to increase their costs in a contract. This document is used to provide proof of increased costs in a contract and to make sure that both parties are in agreement about the additional costs. There are two main types of Minnesota Affidavit of Increased Costs: the Standard Affidavit and the Special Purpose Affidavit. The Standard Affidavit is used when the increased costs are related to the normal and expected costs of the contract. The Special Purpose Affidavit is used when the increased costs are not related to the normal and expected costs of the contract. The Special Purpose Affidavit must be approved by the Minnesota Department of Administration and must include details of the increased costs, an explanation of why the costs are necessary, and the signature of both parties.
