Rule 25.Substitution of Parties
Last verified July 1, 2026
Full Text of Rule 25
Plain-English Summary
A lawsuit does not necessarily end because something happens to one of the people involved. If a party dies and the underlying claim survives (meaning it is not the type of claim that legally dies with the person), the court can order that the proper successor or representative be substituted in. Either the deceased party’s representatives or any other party in the case can make that motion, and it has to be served on the other parties the normal way and on any non-parties the way a summons would be served. When there are multiple plaintiffs or multiple defendants and the right being enforced survives only among the ones still living, the case does not stall at all — the death gets noted in the record and the case continues with the surviving parties.
If a party becomes legally incompetent while the case is pending, the same logic applies: the case does not abate because of that disability, and the court can allow it to continue with the incompetent party’s representative stepping in, using the same motion procedure as in a death situation.
If a party transfers their interest in the case to someone else — selling a claim, assigning a contract, or something similar — the lawsuit does not automatically follow the interest. It can keep going in the name of the original party unless the court, on motion, orders that the new interest-holder be substituted in or added alongside the original party.
Public officials get their own version of this rule. If a public officer who is a party dies, resigns, or otherwise leaves office while the case is pending, the case can continue against or on behalf of their successor, but only if it is shown to the court’s satisfaction that there is a real need to keep the case going. That substitution can also happen if it is shown that the successor is picking up or continuing what their predecessor was doing in the case. Before any of this happens, the affected party or officer gets reasonable notice and a chance to object, unless they have already agreed to it.
