(a) If genetic tests have been performed with respect to a child, the child’s mother, and a male alleged, or alleging himself, to be the child’s father, the test results constitute a conclusive determination of paternity, effective on the date on which the report under par. (c) is submitted to the state registrar, which has the same effect as a judgment of paternity, if all of the following apply:

1. Both the child’s mother and the male are over the age of 18 years.

2. The genetic tests were required to be performed by a county child support agency under s. 59.53 (5) pursuant to s. 49.225 .

3. The test results show that the male is not excluded as the father and that the statistical probability of the male’s parentage is 99.0 percent or higher.

4. No other male is presumed to be the father under s. 891.405 or 891.41 (1) .

(b) When the county child support agency under s. 59.53 (5) receives genetic test results described in par. (a) 3. and the requirements under par. (a) are satisfied, the county child support agency shall send notice to the mother and male by regular mail at their last-known addresses. The notice must be sent at least 15 days in advance of the date on which the county child support agency intends to file the report under par. (c) and shall advise the mother and male of all of the following:

1. The test results.

4. That the mother or the male, or both, may object to the test results by submitting an objection in writing to the county child support agency no later than the day before the date specified in subd. 2. , and that, if either the mother or the male timely submits an objection, the state will commence a paternity action.

(c)

(b) 4. , the county child support agency shall file with the state registrar a report showing the names, dates, and birth places of the child and the father, the social security numbers of the mother, father, and child, and the maiden name of the mother on a form prescribed by the state registrar, along with the fee set forth in s. 69.22 (5) , if any, which the county child support agency shall collect.

2. The department shall pay, and may not require the county or county child support agency to reimburse the department, for the cost of a fee for inserting the father’s name on a birth certificate under s. 69.15 (3) (a) 3. if the county child support agency is unable to collect the fee.

(d) If either the mother or the male timely submits an objection under par. (b) 4. , the county child support agency shall commence an action under s. 767.80 (1) on behalf of the state. The genetic test results described in par. (a) are admissible in an action commenced under this paragraph.

(2) Actions. Unless sub. (1) (d) applies, an action affecting the family concerning custody, child support, or physical placement rights may be brought under this subsection with respect to a child’s mother and a male who, along with the child, were the subjects of genetic tests, the results of which constitute a conclusive determination of paternity under sub. (1) . Except as provided in s. 767.407 , in an action under this subsection the court may appoint a guardian ad litem for the child.

(3) Orders. In an action under sub. (2) , if the child’s custodial and noncustodial parent had notice of the hearing, the court shall make an order that contains all of the following provisions:

(a) Orders for the legal custody of and periods of physical placement with the child, determined in accordance with s. 767.41 .

(b) An order requiring either or both of the parents to contribute to the support of any child of the parties who is less than 18 years old, or any child of the parties who is less than 19 years old if the child is pursuing an accredited course of instruction leading to the acquisition of a high school diploma or its equivalent, determined in accordance with s. 767.511 .

1. An order establishing the amount of the father’s obligation to pay or contribute to the reasonable expenses of the mother’s pregnancy and the child’s birth. The amount established may not exceed one-half of the total actual and reasonable pregnancy and birth expenses. The order also shall specify the court’s findings as to whether the father’s income is at or below the poverty line established under 42 USC 9902 (2), and shall specify whether periodic payments are due on the obligation, based on the father’s ability to pay or contribute to those expenses.

2. If the order does not require periodic payments because the father has no present ability to pay or contribute to the expenses, the court may modify the judgment or order at a later date to require periodic payments if the father has the ability to pay at that time.

(e) An order requiring either or both parties to pay or contribute to the costs of guardian ad litem fees, if any, and other costs.

(a) , the court may include an order changing the surname of the child to a surname that consists of the surnames of both parents separated by a hyphen or, if one or both parents have more than one surname, of one of the surnames of each parent separated by a hyphen, if all of the following apply:

1. Only one parent requests that the child’s name be changed, or both parents request that the child’s name be changed but each parent requests a different name change.
