(1) NOTICE TO PARTIES. If the respondent is present at a hearing prior to the determination of paternity, the court shall, at least one time at one such hearing, inform the parties of the items in s. 767.813 (5g).
(1m) PATERNITY ALLEGATION BY MALE OTHER THAN HUSBAND; WHEN DETERMINATION NOT IN BEST INTEREST OF CHILD. In an action to establish the paternity of a child who was born to a woman while she was married, if a male other than the woman’s husband alleges that he, not the husband, is the child’s father, a party may allege that a judicial determination that a male other than the husband is the father is not in the best interest of the child. If the court or a supplemental court commissioner under s. 757.675 (2) (g) determines that a judicial determination of whether a male other than the husband is the father is not in the best interest of the child, no genetic tests may be ordered and the action shall be dismissed.
(2) ORDER FOR TESTS. If at the first appearance it appears from a sufficient petition or affidavit of the child’s mother or an alleged father or from sworn testimony of the child’s mother or an alleged father that there is probable cause to believe that any of the males named has had sexual intercourse with the mother during a possible time of the child’s conception, the court may, or upon the request of any party shall, order any of the named persons to submit to genetic tests. The tests shall be conducted in accordance with s. 767.84. The court is not required to order a person who has undergone a genetic test under s. 49.225 to submit to another genetic test under this subsection unless a party requests additional tests under s. 767.84 (2).
(3) ORDERS IF STATEMENT ON FILE. At the first appearance, if a statement acknowledging paternity under s. 69.15 (3) (b) 1. or 3. that was signed and filed before April 1, 1998, is on file, the court may enter an order for child support, legal custody or physical placement and, if the respondent who filed the statement does not dispute his paternity, may enter a judgment of paternity.

Official Notes

Wisconsin prints certain labelled notes with the statute — effective-date notes, cross-references, and notes of the Judicial Council. They are reproduced verbatim below. The unlabelled digest of court decisions that the Legislative Reference Bureau prints after them is annotation rather than statute, and is not reproduced.

NOTE: 2005 Wis. Act 443 contains explanatory notes. Before dismissing a petition without considering the merits, sub. (1m) requires the trial court to conduct a hearing to determine the child’s best interests. J.F. v. R.B., 154 Wis. 2d 637, 454 N.W.2d 561 (Ct. App. 1990). Sub. (1m) is constitutional. The court has an obligation to refuse to allow blood tests if the tests may result in a determination that the person alleging his paternity is the natural father and that determination would not be in the best interest of the children. W.W.W. v. M.C.S., 161 Wis. 2d 1015, 468 N.W.2d 719 (1991). The plain language of sub. (1m) does not limit the court’s authority to dismiss paternity actions to cases in which no genetic tests have been performed. The circuit court in this case correctly disregarded the genetic testing upon which a nonspouse who asserted paternity relied because the testing was not completed pursuant to court order. The court properly ruled that a judicial determination that the nonspouse was the child’s father would not be in the child’s best interest. Stuart S. v. Heidi R., 2015 WI App 19, 360 Wis. 2d 388, 860 N.W.2d 538, 14-1487. Parental status that rises to the level of a constitutionally protected liberty interest does not rest solely on biological factors, but rather, is dependent upon an actual relationship with the child in which the parent assumes responsibility for the child’s emotional and financial needs. Stuart S. v. Heidi R., 2015 WI App 19, 360 Wis. 2d 388, 860 N.W.2d 538, 14-1487. Circuit courts have discretion to dismiss actions without prejudice under this section. Section 767.88 expressly contemplates that circuit courts possess discretion to dismiss a paternity action with or without prejudice prior to a trial on the merits. Consequently, s. 767.88 strongly suggests the legislature intended that courts have such discretion when dismissing actions under this section when the ultimate issue of paternity is similarly not reached. Douglas L. v. Arika B., 2015 WI App 80, 365 Wis. 2d 257, 872 N.W.2d 357, 14-2656. In re Paternity of C.A.S. and C.D.S.: The New Status of Putative Fathers’ Rights in Wisconsin. Pabst. 1992 WLR 1669.

Plain-English Summary

The first substantive hearing, and where several of the subchapter's hardest questions get asked.

The explanation. If the respondent is present at a hearing before paternity is determined, the court must at least once inform the parties of the items in the summons's notice to parties — what a paternity judgment does, the right to counsel and its limits, the burden of proof, genetic tests, the available defences, the right to a jury, and what happens on a failure to appear.

A child born to a married woman. Where a man other than the husband alleges that he, not the husband, is the father, any party may allege that a judicial determination to that effect is not in the child's best interest. If the court or a supplemental court commissioner so determines, no genetic tests may be ordered and the action is dismissed. This is the marital family's protection, and it is decided before the biology, not after.

Tests. Where a sufficient petition, affidavit or sworn testimony shows probable cause to believe one of the named males had intercourse with the mother during a possible time of conception, the court may order genetic tests, and on any party's request must. Someone already tested under the administrative provision is not retested unless a party asks for additional tests.

An old acknowledgment on file. Where a statement acknowledging paternity signed and filed before April 1, 1998 is on file, the court may enter orders for support, custody and placement at the first appearance, and if the respondent who filed it does not dispute paternity, may enter judgment.

Frequently Asked Questions

What happens at the first appearance in a Wisconsin paternity case?

The court informs the parties of the items in the notice to parties, may order genetic tests where probable cause is shown, and may enter orders where a pre-1998 acknowledgment is on file.

Can a man challenge the paternity of a married woman's child?

He may allege that he, not the husband, is the father — but any party may allege that a judicial determination to that effect is not in the child's best interest, and if the court so determines, no genetic tests may be ordered and the action is dismissed.

Must the court order a DNA test if I ask?

Where probable cause of intercourse during a possible time of conception is shown, the court shall order tests on the request of any party.
