Evidence is anything that tends to prove or disprove a material or relevant fact alleged in a lawsuit or other legal proceeding. Witness testimony, documents, contracts, email messages, photographs, medical bills, video images, and voice recordings are common pieces of evidence.
In Michigan, evidence is regulated by both state statutes and the Michigan Rules of Evidence. These rules determine what evidence is admissible in court to prove or disprove facts pertinent to a case. The admissibility of evidence such as witness testimony, documents, contracts, email messages, photographs, medical bills, video images, and voice recordings is subject to relevance, reliability, and various other evidentiary principles. Evidence must be relevant to the issues in the case, meaning it must make a fact more or less probable than it would be without the evidence. Additionally, the evidence must not be excluded by the rules against hearsay, unless an exception applies, and it must not be overly prejudicial, confusing, or a waste of time. The Michigan Rules of Evidence are largely modeled after the Federal Rules of Evidence, ensuring a degree of uniformity with federal standards. However, state-specific nuances and case law interpretations by Michigan courts can affect how evidence is handled in Michigan's legal proceedings.
