Wisconsin Abortion Laws and the 20-Week Limit

Abortion is legal in Wisconsin until about 22 weeks of pregnancy. In July 2025 the state Supreme Court ruled that an 1849 law does not ban it, but it left open whether the state constitution protects abortion.

By Resist Now Published

Yes, abortion is legal in Wisconsin until 20 weeks after fertilization, which is about 22 weeks of pregnancy. After that point, state law allows an abortion only in a medical emergency. A provider who breaks the limit commits a felony, and the law bars any penalty against the patient (Wis. Stat. 253.107).

The Ruling on Wisconsin’s 1849 Abortion Law

After the U.S. Supreme Court overturned Roe v. Wade in June 2022, providers in Wisconsin stopped offering abortions because of an 1849 law. Attorney General Josh Kaul sued that month, arguing the old law did not ban abortion. A trial court agreed in December 2023, and abortions resumed (NPR).

Wisconsin's 1849 abortion law in court: June 2022: Providers stop abortions (Roe v. Wade is overturned, and the attorney general sues over the 1849 law.). Dec. 2023: Trial court rules (The court finds the 1849 law does not ban abortion, and abortions resume.). July 2025: Supreme Court rules 4-3 (Later laws "functionally repealed" the 1849 ban; a separate constitutional case is dismissed.).

On July 2, 2025, the Wisconsin Supreme Court ruled 4-3 that the Legislature had functionally repealed the 1849 law. The majority wrote that 50 years of later laws regulating “the ‘who, what, where, when, and how’ of abortion” were meant to replace the near-total ban. In dissent, Justice Annette Ziegler wrote that the majority “picks and chooses which abortion statutes remain in force” (NPR).

Wisconsin Abortion Rules That Still Apply

Because the required information must come in person a day ahead, a patient usually makes two visits at least 24 hours apart.

What Is Unsettled in Wisconsin

The 2025 ruling did not decide whether Wisconsin’s constitution protects abortion. The court dismissed Planned Parenthood of Wisconsin’s separate case, because it could reach that question only if the 1849 law were a ban (NPR).

Wisconsin voters cannot put a constitutional amendment on the ballot by petition; only the Legislature can. So any new limit or new protection has to pass the Legislature and, for an ordinary law, get the governor’s signature. The governor’s office and every Assembly seat are on the November 3, 2026 ballot, along with 17 of 33 Senate seats.
