Rule 3.230.Actions Under the Summary Support and Paternity Act
Subchapter 3.200 — Domestic Relations Actions · Last verified September 5, 2026
Full Text of Rule 3.230
Plain-English Summary
MCR 3.230 supplies the procedure for expedited paternity and support actions under the Summary Support and Paternity Act, MCL 722.1491 et seq. Subrule (A)(1) leaves the ordinary domestic relations rules in place except where this rule or the act says otherwise. The design shows through the whole rule: carry a paternity or support case to judgment on forms and notices, and hold a hearing only where the rule calls for one.
Who brings the action
Subrule (A)(2) defines the players. A IV-D agency is the county agency that provides support and paternity establishment services under MCL 722.1501. The plaintiff is the child's mother, father, or alleged father on whose behalf the agency files, or the Michigan Department of Health and Human Services when the agency files on behalf of a child. An expedited paternity action establishes paternity, or paternity and support; an expedited support action establishes a parent's support obligation under MCL 722.1499.
Two ways to start, and no summons
Under subrule (B)(1) the agency files either a complaint and notice or a request to enter a consent agreement with a judgment or order the parties have already signed. Either way subrule (B)(2) has the clerk assign a case number and judge and issue no summons under MCR 2.102. Subrule (B)(4) sets the complaint requirements, including verification and signature by the mother or alleged father, or signature on information and belief by the agency. Subrule (B)(7) lifts the verified statement requirement of MCR 3.206(C) unless the court directs otherwise.
The notice and its expiration date
Subrule (B)(5) makes the notice carry the load a summons carries elsewhere. It is titled in the name of the people of the state of Michigan, signed by the agency, and it tells the defendant that responses are due within 21 days and that an order may enter granting the requested relief without further notice or hearing if nothing is filed. It bears an expiration date no more than 126 days after the action is filed. Under subrule (D)(1) an unserved action is deemed dismissed without prejudice when the notice expires, unless the defendant responded. Subrule (D)(2) requires the court to set that dismissal aside without a hearing if the agency shows within 28 days of expiration that the defendant did receive timely notice or had already submitted to the court's jurisdiction.
Setting support
Subrule (E) lets the agency serve a notice proposing a support amount, calculated under the Michigan Child Support Formula or a documented deviation, with a calculation report stating the amounts, the proposed effective date, and the facts and assumptions behind them. A party has 21 days to object on a mistake in those facts or assumptions or an error in the calculation. Without an objection the order goes to the court for entry.
Responding, and not responding
Subrule (F)(1) sets the same 21-day window for a response, and subrule (F)(4) requires the agency, within 14 days after that window closes, to schedule genetic testing where a party in a paternity action asked for it, set a hearing on contested matters, or submit a proposed order covering what is uncontested. Subrule (G)(1) turns off MCR 3.210(B). Subrule (G)(3) draws a hard line: when an alleged father sues the child's mother and she does not admit paternity, the court may not determine paternity except on genetic test results.
Subrule (H)(2) allows entry without a hearing once the court is satisfied that the parties had proper notice and an opportunity to file a response, that statutory and rule requirements were met, and that the terms follow the law. Subrule (H)(3) pulls the other way in two situations. When the proposed judgment asks for relief different from what the complaint requested, or when the agency lacks facts enough to complete the judgment without a judicial determination, the agency must schedule a hearing and serve the motion, notice of hearing, and proposed judgment at least 14 days before it. Subrule (H)(4) lets the court send a proposed judgment back for a modified version, added affidavits, or a hearing within 14 days. After entry, subrule (H)(7) gives the agency 7 days to serve the judgment as entered.
Frequently Asked Questions
Does a summons issue in an expedited paternity or support action?
How long does a defendant have to respond?
The window is 21 days. Subrule (B)(5)(c) requires the notice to say that written responses, agreements, and other actions must be filed with the court within 21 days after service, and that an order or judgment may enter granting the requested relief without further notice or hearing if the defendant does not respond. Subrule (F)(1) repeats the 21-day window for a response to a notice under subrule (B) or a notice setting support under subrule (E).
What happens if the defendant is never served?
The case falls away on its own. Under subrule (B)(5)(d) the notice carries an expiration date no later than 126 days after filing, and subrule (D)(1) deems the action dismissed without prejudice on expiration if the defendant was not served and did not respond.
Subrule (D)(2) provides the fix: the court must set the dismissal aside without a hearing if the IV-D agency shows, within 28 days of the expiration, that the defendant did receive timely notice or had submitted to the court's jurisdiction before the dismissal.
How is child support set under MCR 3.230?
Subrule (E)(1) lets the IV-D agency serve a notice proposing a support amount when the complaint is filed or any time after paternity or a duty of support is established. The amount comes from the Michigan Child Support Formula or a properly documented deviation, and the notice or an accompanying calculation results report states the amounts, the proposed effective date, and the facts and assumptions behind the calculation.
Under subrule (E)(2) a party has 21 days to object based on a mistake in those facts or assumptions or an error in the calculation. If no objection is filed, an order in the proposed amounts goes to the court for entry without further notice or hearing. Subrule (E)(3) lets the agency recalculate and reissue the notice if new information arrives before an order is submitted.
Can paternity be established without genetic testing?
Sometimes. Subrule (G)(2) says that if neither party requests genetic tests and a defendant alleged to be the father does not otherwise defend within 21 days after receiving notice, the IV-D agency may submit a proposed judgment establishing him as the child's legal father.
Subrule (G)(3) runs the other way when an alleged father brings the action against the child's mother. If she does not admit his paternity, the court may not determine paternity except on genetic test results.
When must the IV-D agency serve an entered judgment or order?
The deadline is 7 days after entry. Subrule (H)(7) requires the agency to serve a copy of the judgment or order as entered by the court on all parties within 7 days after entry, as provided by MCR 3.203, and to file a proof of service promptly.
