Verified current as of July 19, 2026

This form is used to show a court that you made a good faith effort to find and notify someone who is involved in a legal case, even though you couldn't locate them. A person would need this form when they're required to serve legal papers on another party but genuinely cannot find that person despite trying multiple ways to reach them.
