The MC-030 is a written statement where someone describes facts they know about a case and swears under penalty of perjury that everything they wrote is true, used instead of testifying in court in person. Anyone involved in a court case—a party to the lawsuit, a witness, or someone with knowledge of relevant facts—would use this form to provide their account of events to the judge.
This form must be printed and filled by hand, or opened in Adobe Acrobat.
