Mich. Comp. Laws § 600.5225
Each proof of claim must be sworn to and must state the actual amount unpaid and owing, the actual consideration thereof, when the same was contracted, when the same has become or will become due, whether any or what securities are held therefor, whether any and what payments have been made thereon, that the sum claimed is justly owing from the assignor to the claimant, and that the claimant has not, nor has any other person for his use, received any security or satisfaction whatever other than that set forth in such proof. When the claim is founded upon an account an itemized statement thereof shall be given and when the claim is founded upon any note or similar instrument, a copy thereof shall be attached and the production of the original may be required by the assignee.
