A filled-in Form MC-040 example: a plaintiff gives a new address

Form MC-040 example filled out, example: a plaintiff gives a new address
Jane Ann Sample, a self-represented plaintiff, fills out form MC-040. As of March 1, 2026, she has a new address and a friend mails it to one party. The picture shows both pages, and none of its entries is real. She signs on March 2, 2026, and her friend Tom Helper mails the notice in Anytown on March 3, 2026. She is not an attorney, so Attorney For in The case and the court stays empty. Only the plaintiff box in The self-represented party or the attorney for is marked, so the defendant, petitioner, respondent, other and additional parties boxes stay empty. The Mailing address line in The new address or other contact information is left blank because it is the same as the street address. One person is served by mail from the post office, so the b. box of item 3 stays empty, and nothing goes in the names of b., c. and d. or in the additional persons box because only one person is served.
