Wisconsin Grandparents' Rights: Michels v. Lyons Sets the Real Standard

Grandparents in Wisconsin do not have automatic rights to see their grandchildren. Wisconsin's grandparent-visitation statute, read on its own, looks like an open-ended best-interest law with no protection built in for a fit parent's own decision. That is not the operative law. A 2019 Wisconsin Supreme Court decision rewrote how that statute actually functions, without the legislature ever changing a word of it.

This guide covers what the statute's bare text says, the case that is the real controlling law, the separate custody track, adoption cutoffs, and what filing actually involves.

What Wisconsin's Statute Says on Its Face

Wisconsin's general grandparent-visitation provision, Wis. Stat. § 767.43(1), reads as a pure best-interest test on its face, with no presumption favoring the parent's decision and no requirement to show harm. Read in isolation, this is exactly the kind of open-ended statute Troxel v. Granville, 530 U.S. 57 (2000), warned could violate a fit parent's constitutional rights.

That is precisely why the case law discussed below matters so much for Wisconsin: the statute's text alone would understate how demanding a Wisconsin grandparent-visitation case actually is.

Michels v. Lyons: The Case That Is the Real Law

In Michels v. Lyons (In re Visitation of A.A.L.), 2019 WI 57, 387 Wis. 2d 1, 927 N.W.2d 486 (Wis. 2019), the Wisconsin Supreme Court confronted § 767.43 head-on. The court held that because a fit parent has a fundamental liberty interest in raising their own child, the statute has to withstand strict scrutiny, the most demanding constitutional standard courts apply. The court found the statute facially constitutional, meaning it can be applied consistently with that standard, but only because it read into the statute a requirement the text itself never stated: a grandparent must overcome a presumption favoring the fit parent's visitation decision with clear and convincing evidence that the parent's decision is not in the child's best interest.

On the specific facts before it, the court held the statute had been applied unconstitutionally, because the grandparent in that case had not met that heightened clear-and-convincing standard, despite having a long, close relationship with the child. The court vacated the visitation order the trial court had granted.

The upshot: Wisconsin's real, operative standard under the general provision is presumption-and-rebuttal, not bare best-interest, even though the statute's own words never say so. Anyone researching Wisconsin grandparent-visitation law by reading only the statute text would come away with a materially wrong picture of how hard the case actually is.

The Nonmarital-Child Route

A separate, narrower provision, § 767.43(3), applies only where a child was born out of wedlock, paternity has been legally established, and the grandparent maintained or attempted to maintain a relationship with the child that a custodial parent then prevented. This route uses a softer factor, whether the grandparent is likely to act contrary to the custodial parent's decisions, rather than the formal clear-and-convincing presumption Michels reads into the general provision.

Custody: The Psychological Parent Doctrine

Wisconsin has no dedicated statute letting a grandparent petition for custody in a private dispute with a fit parent. The real-world vehicle instead is a judge-made legal theory, the «psychological parent» doctrine, that originates from a Wisconsin Supreme Court decision in this area of family law. This guide names that doctrine as the relevant background because it is frequently discussed in Wisconsin custody practice, but does not characterize its underlying case's specific holding here, since the full opinion was not independently reviewed for this article. See can grandparents get custody for how this harder track generally compares to other states' approaches. Wisconsin's UCCJEA jurisdictional statute (§ 822.02) defines «person acting as a parent» for jurisdictional purposes, but it is not itself a standing or merits custody statute.

Adoption Cutoff

Under the nonmarital-child provision, § 767.43(3)(c), the child must not have been adopted for a grandparent to maintain standing under that section, and the text does not state a stepparent or other relative exception. That makes it one of the stricter adoption cutoffs among the states covered in this cluster.

Court Procedure

Wisconsin grandparent-visitation petitions are filed in circuit court. Section 767.43(1) requires that parents receive notice of a hearing, which implies the process operates within some form of court proceeding rather than as a wholly freestanding suit with no other case involved, though this was not fully confirmed for this guide. No official statewide fee schedule was located for this guide; confirm current filing costs with the circuit court clerk in the county where you plan to file.

Before You File: Mediation and the Real Cost of Litigation

Wisconsin's real standard, per Michels v. Lyons, is considerably more protective of parents than the bare statute suggests. A grandparent needs clear and convincing evidence, not just a sympathetic case, even under the general provision.

As in every state, litigation against your own child's parenting decision is adversarial and can strain family relationships regardless of outcome. Mediation or a direct family conversation is worth trying first, and a Wisconsin family-law attorney can assess whether your specific facts plausibly meet the clear-and-convincing bar before a petition is filed.
