Overview of Wisconsin Statute of Limitations

Wisconsin's statute of limitations sets strict deadlines for filing lawsuits in both civil and criminal cases. These deadlines are codified primarily in the Wisconsin Statutes Chapter 893 and vary depending on the type of claim. Missing a deadline can result in your case being dismissed, regardless of how strong your claim may be.

The time limits range from as short as 120 days for claims against government entities to 6 years for written and oral contract disputes. Wisconsin is notable for applying the same 6-year limitations period to both written and oral contracts, which is longer than many other states. Some claims, such as medical malpractice, have complex rules with multiple overlapping deadlines and a statute of repose.

Key point: The statute of limitations clock typically starts on the date the injury occurred or the date the injury was discovered (or should have been discovered). Wisconsin courts recognize the discovery rule in many types of cases. Always verify the applicable deadline with a qualified Wisconsin attorney before relying on any general information.

Special rules may apply for claims involving minors, government entities, medical malpractice, products liability, and other specific situations. Always consult with a qualified Wisconsin attorney for advice on your particular case.

Personal Injury Claims in Wisconsin

Under Wis. Stat. § 893.54, Wisconsin's statute of limitations for personal injury claims is 3 years from the date the injury occurred. This applies to a wide range of cases, including:

  • Car accidents and motor vehicle collisions
  • Slip and fall / premises liability cases
  • Assault and battery
  • Dog bites and animal attacks
  • Workplace injuries (outside of workers' compensation)
  • Product liability injuries

Discovery Rule

Wisconsin courts apply the discovery rule in personal injury cases. Under this doctrine, the statute of limitations does not begin to run until the plaintiff discovered, or through the exercise of reasonable diligence should have discovered, the injury and its cause. This is commonly applied in:

  • Toxic exposure cases
  • Occupational diseases
  • Medical malpractice (hidden injuries)
  • Cases involving latent injuries

Minors

If the injured person is under 18 at the time of the injury, the statute of limitations is generally tolled (paused) until they reach the age of majority. Under Wis. Stat. § 893.16, the 3-year clock then starts on their 18th birthday, giving them until age 21 to file a lawsuit. Exceptions exist for medical malpractice claims involving minors.

Government claims exception: If your personal injury claim is against a government entity (city, county, state agency, or public school), you must file a notice of injury within 120 days under Wis. Stat. § 893.80. The regular 3-year deadline does not apply to government defendants.

Contract Disputes in Wisconsin

Wisconsin is notable for applying the same statute of limitations period to both written and oral contracts, which is longer than many other states.

Written and Oral Contracts

Under Wis. Stat. § 893.43, the statute of limitations for actions on a contract or other liability created by a written instrument is 6 years from the date the cause of action accrues. Wisconsin courts have also applied this same 6-year period to oral contracts. This applies to employment agreements, lease agreements, business contracts, promissory notes, and other agreements. The clock starts on the date the breach occurred.

UCC Sales of Goods

For contracts involving the sale of goods, Wisconsin's version of the Uniform Commercial Code (Wis. Stat. § 402.725) sets a 4-year statute of limitations. The parties may reduce this to not less than 1 year, but may not extend it beyond 4 years.

Accrual of Contract Claims

In Wisconsin, a breach of contract claim generally accrues on the date of the breach, not the date the breach was discovered. However, Wisconsin courts have recognized limited exceptions where the discovery rule may apply, such as in cases involving fraud in the inducement or fiduciary relationships.

Note: Wisconsin's 6-year statute of limitations for contracts is one of the more favorable deadlines for plaintiffs in the Midwest. Whether a contract is written or oral, you generally have 6 years from the date of breach to file suit.

Medical Malpractice in Wisconsin

Wisconsin's medical malpractice statute of limitations is governed by Wis. Stat. § 893.55. The rules include both a statute of limitations and a statute of repose:

Statute of Limitations

The statute of limitations for medical malpractice claims is the longer of:

  • 3 years from the date of the alleged negligent act or omission
  • 1 year from the date the injury was discovered or reasonably should have been discovered

This means that even if you did not discover the injury right away, you generally have at least 1 year from the date of discovery to file a claim.

Statute of Repose

Under Wis. Stat. § 893.55, no action may be brought more than 5 years after the date of the alleged act or omission, regardless of when the injury was discovered. This is an absolute bar with limited exceptions.

Exceptions

  • Foreign object: If a foreign object was left in the patient's body, the 5-year statute of repose does not apply
  • Minors: Special rules apply for claims involving minors; the statute of repose does not bar actions filed on behalf of a minor within the time limits specified by law
  • Fraud: If the healthcare provider fraudulently concealed the error, the statute of limitations may be tolled

Pre-Suit Requirements

Wisconsin requires that medical malpractice plaintiffs comply with specific pre-suit procedures. Before filing a medical malpractice lawsuit, the plaintiff must:

  • Serve a notice of intent to sue on each potential defendant at least 90 days before filing
  • Provide an offer of settlement or demand for arbitration along with the notice
  • Obtain a written opinion from a medical expert that the defendant's treatment fell below the standard of care

Compliance with these pre-suit requirements is mandatory, and failure to comply can result in dismissal of the lawsuit.

Warning: Medical malpractice cases in Wisconsin have strict procedural requirements, including the pre-suit notice, offer of settlement, and expert opinion requirements. Consult with an experienced Wisconsin medical malpractice attorney immediately if you believe you have a claim.

Property Damage Claims in Wisconsin

Under Wis. Stat. § 893.53, the statute of limitations for property damage claims in Wisconsin is 3 years. This applies to:

  • Damage to real property (land, buildings, structures)
  • Damage to personal property (vehicles, equipment, belongings)
  • Trespass to real property
  • Conversion (theft or unauthorized use of personal property)
  • Vandalism and intentional property damage

The clock generally starts on the date the damage occurred. For latent damage that is not immediately discoverable (such as construction defects), the discovery rule may apply under Wisconsin case law, but a separate statute of repose may also limit the time to file.

Construction-Related Claims

Wisconsin has a statute of repose for construction-related claims. Under Wis. Stat. § 893.89, actions against contractors, architects, engineers, and others involved in the construction or improvement of real property must generally be filed within 10 years of the date of substantial completion of the construction. This is an absolute deadline that applies regardless of when the defect was discovered.

Debt Collection in Wisconsin

The statute of limitations for debt collection in Wisconsin is 6 years for most types of debt, which is longer than many other states. Wisconsin applies the same 6-year period to both written and oral contracts.

Type of Debt Statute of Limitations Legal Basis
Written contract (loans, promissory notes) 6 years Wis. Stat. § 893.43
Oral contract 6 years Wis. Stat. § 893.43
Open-ended account (credit cards) 6 years Wis. Stat. § 893.43
Auto loan deficiency 6 years Wis. Stat. § 893.43
Court judgment 20 years Wis. Stat. § 893.15

When Does the Clock Start?

For most debts, the statute of limitations starts from the date of last payment or the date of default, whichever is later. In Wisconsin, making a partial payment on a debt may restart the statute of limitations clock. Each payment on an account may reset the deadline.

Important: After the statute of limitations expires, debt collectors can still attempt to collect the debt, but they cannot successfully sue you. However, making a partial payment or acknowledging the debt in writing may restart the clock. Wisconsin also has consumer protection laws under the Wisconsin Consumer Act (Wis. Stat. Ch. 421–427) that provide additional protections against unfair debt collection practices.

Wrongful Death Claims in Wisconsin

Under Wis. Stat. § 893.54, the statute of limitations for wrongful death claims in Wisconsin is 3 years from the date of the decedent's death. This applies when a person's death is caused by the wrongful act, neglect, or default of another.

Wrongful death claims in Wisconsin may be filed by the personal representative of the decedent's estate on behalf of the decedent's surviving spouse, domestic partner, children, or other heirs. Wisconsin's wrongful death statute (Wis. Stat. § 895.04) allows recovery for both pecuniary losses and the loss of society and companionship.

Common Wrongful Death Scenarios

  • Fatal car or truck accidents
  • Medical malpractice resulting in death
  • Workplace fatalities
  • Defective products causing death
  • Intentional acts of violence
  • Premises liability incidents (e.g., drowning, unsafe conditions)

Survival Actions

In addition to wrongful death claims, Wisconsin allows "survival actions" under Wis. Stat. § 895.01, which allow the estate of the deceased to pursue claims the deceased could have brought had they survived (such as pain and suffering before death). The statute of limitations for survival actions is also 3 years under Wis. Stat. § 893.54.

If the wrongful death claim is against a government entity, the shorter notice deadlines under Wis. Stat. § 893.80 apply instead.

Claims Against Government Entities in Wisconsin

Wisconsin imposes a significantly shorter deadline for claims against government entities under Wis. Stat. § 893.80. The process requires advance notice before filing a lawsuit.

Notice of Claim Requirement

Under Wis. Stat. § 893.80, you must present a written notice of claim to the relevant governmental entity within 120 days of the event giving rise to the claim. The notice must include:

  • The circumstances of the claim
  • The amount of the claim (in most cases, claims against governmental units are capped)
  • The address of the claimant
  • The name of the governmental entity involved

Government Response

The governmental entity then has 120 days to allow or disallow the claim. If the claim is disallowed (which is the typical outcome), you have 6 months from the date of disallowance to file a lawsuit in court.

Damage Caps

Wisconsin imposes statutory caps on damages recoverable against governmental entities:

  • $50,000 for claims against the state, its agencies, and state employees
  • $50,000 for claims against any other governmental entity (cities, counties, etc.)
  • $150,000 aggregate cap for claims against a municipal corporation

This applies to claims against:

  • The State of Wisconsin and its agencies
  • Cities and municipalities
  • Counties
  • Public school districts and universities
  • Public transit authorities
  • Any other political subdivision of the state

Critical: Missing the 120-day notice deadline almost always permanently bars your claim against a government entity. Unlike private lawsuits, there is very little room for late filings or exceptions. If you believe you have a claim against a government entity, act immediately and consult with a Wisconsin attorney.

Criminal Statute of Limitations in Wisconsin

Wisconsin's criminal statute of limitations is governed by Wis. Stat. § 971.04. The deadlines vary based on the severity of the offense:

Offense Type Statute of Limitations Legal Basis
Class A felony (e.g., first-degree intentional homicide) No limit Wis. Stat. § 971.04(1)
Homicide (all degrees) No limit Wis. Stat. § 971.04(1)
Sexual assault of a child under 13 No limit (if reported before age 18 or DNA evidence) Wis. Stat. § 971.04(1)
Class B through I felonies (general) 6 years Wis. Stat. § 971.04(2)
Sexual assault (second degree and above) No limit (if reported within 3 years) Wis. Stat. § 971.04(2)
Misdemeanors 3 years Wis. Stat. § 971.04(4)
Forgery 6 years Wis. Stat. § 971.04(2)

Note: Wisconsin has expanded the list of crimes with no statute of limitations in recent years. In addition to homicide, certain sexual offenses involving children and offenses where DNA evidence identifies a suspect carry no time limit. The time limit for certain offenses may also be tolled if the defendant is not usually resident within Wisconsin.

Crimes Against Children (Extended Limits)

Wisconsin provides extended time limits for crimes against children:

  • Before victim turns 45: 2nd-degree sexual assault, repeated sexual assault, intentional physical abuse, sexual exploitation, sex trafficking, incest, sexual enticement, computer-facilitated sex crimes, prostitution, sexual assault by school personnel
  • Before victim turns 26: Reckless physical abuse, mental abuse, enticement causing harm, giving a child illegal drugs
  • No limit: 1st-degree sexual assault of a child, repeated sexual assault of the same child

DNA Tolling

Wisconsin law extends the statute of limitations by 1 additional year if a DNA profile matches an alleged perpetrator, even if the standard limitations period has expired. This applies to 2nd-degree sexual assault, 2nd/3rd-degree reckless homicide, and other felonies.

When Does Criminal Prosecution Officially Begin?

Under Wisconsin law, prosecution is considered officially commenced when:

  • Complaint filed — A sworn statement alleging criminal conduct
  • Information filed — A formal charge filed by the prosecutor
  • Indictment found — A formal charge issued by a grand jury
  • Warrant issued — An arrest warrant issued by a judge

Challenging Expired Criminal Charges

If you believe the statute of limitations has expired, your defense attorney can file a motion to dismiss under Wis. Stat. § 971.04.

Tolling and Exceptions in Wisconsin

Under certain circumstances, Wisconsin law allows the statute of limitations to be "tolled" (paused or extended). Common tolling doctrines include:

Minority (Under 18)

If the plaintiff is under 18 at the time the cause of action accrues, the statute of limitations is tolled until they reach the age of majority. This is codified at Wis. Stat. § 893.16. The clock starts on the plaintiff's 18th birthday. However, note the special rules for medical malpractice claims involving minors and the statute of repose.

Mental Incapacity

If the plaintiff is mentally incompetent at the time the cause of action accrues, the statute of limitations may be tolled under Wis. Stat. § 893.16. The disability must exist at the time the cause of action accrues; subsequent disability generally does not toll the limitations period.

Defendant's Absence from the State

Under Wis. Stat. § 893.19, if the defendant is not usually resident within Wisconsin at the time the cause of action accrues, the period of non-residence is not counted toward the statute of limitations. This means the clock pauses while the defendant is out of state.

Discovery Rule

Wisconsin courts recognize the discovery rule in many types of cases. Under this doctrine, the statute of limitations does not begin until the plaintiff discovered, or through the exercise of reasonable diligence should have discovered, the facts giving rise to the claim. This is particularly relevant in:

  • Medical malpractice (hidden injuries)
  • Toxic exposure and environmental contamination
  • Fraud and misrepresentation
  • Professional malpractice (legal, accounting)
  • Occupational diseases

Fraudulent Concealment

If the defendant fraudulently concealed the facts giving rise to the claim, the statute of limitations is tolled until the plaintiff discovered or should have discovered the claim. Wisconsin courts apply this doctrine when the defendant engaged in affirmative acts of concealment intended to prevent the plaintiff from discovering the claim.

Warning: Tolling doctrines are complex and fact-specific. Do not assume the statute of limitations has been extended in your case without consulting a Wisconsin attorney. Courts apply these doctrines narrowly, and the burden of proving tolling is on the plaintiff.

Wisconsin Statute of Limitations: Frequently Asked Questions

What is the statute of limitations for personal injury in Wisconsin?
In Wisconsin, the statute of limitations for personal injury claims is 3 years from the date of the injury under Wis. Stat. § 893.54. This applies to car accidents, slip and fall cases, assault, dog bites, and other injury claims. Wisconsin applies the discovery rule, meaning the clock may start when the injury was discovered or should have been discovered.

What is the statute of limitations for medical malpractice in Wisconsin?
Under Wis. Stat. § 893.55, the statute of limitations for medical malpractice in Wisconsin is the longer of 3 years from the date of the injury or 1 year from the date the injury was discovered or reasonably should have been discovered. However, no claim may be filed more than 5 years after the date of the negligent act regardless of discovery (statute of repose), except for cases involving foreign objects left in the body or claims involving minors. Wisconsin also requires pre-suit notice, an offer of settlement, and a medical expert opinion before filing a lawsuit.
What is the statute of limitations for breach of contract in Wisconsin?
In Wisconsin, the statute of limitations for breach of both written and oral contracts is 6 years under Wis. Stat. § 893.43. Wisconsin is notable for applying the same 6-year limitations period to both written and oral contracts, which is longer than many other states. The clock generally starts on the date the breach occurred, not when the breach was discovered. For contracts involving the sale of goods, the UCC provides a 4-year statute of limitations under Wis. Stat. § 402.725.
What is the statute of limitations for debt collection in Wisconsin?
In Wisconsin, the statute of limitations for debt collection is 6 years for both written and oral contracts under Wis. Stat. § 893.43. This includes loans, promissory notes, credit card debt, and other forms of consumer debt. The clock typically starts from the date of the last payment or the date of default. Making a partial payment or acknowledging the debt in writing may restart the clock. Wisconsin also has consumer protection laws under the Wisconsin Consumer Act that provide additional protections against unfair debt collection practices.
How long do I have to file a claim against a government entity in Wisconsin?
Under Wis. Stat. § 893.80, you must present a written notice of claim to the relevant governmental entity within 120 days of the event giving rise to the claim. The governmental entity then has 120 days to allow or disallow the claim. If the claim is disallowed, you have 6 months from the date of disallowance to file a lawsuit. Missing the 120-day notice deadline almost always permanently bars your claim. Damage caps also apply: $50,000 for claims against the state and $50,000 for claims against other governmental entities.
Can the statute of limitations be extended in Wisconsin?
Yes, under certain circumstances. The statute of limitations can be tolled (paused) if the plaintiff is a minor under 18, is mentally incompetent, or if the defendant has left the state. Wisconsin also recognizes the discovery rule and fraudulent concealment as bases for tolling. However, these doctrines are fact-specific, and the burden of proving tolling is on the plaintiff. Always consult with a Wisconsin attorney to determine if tolling applies to your case.
What is the statute of limitations for childhood sexual abuse in Wisconsin?
Under Wis. Stat. § 893.537, victims of childhood sexual abuse may file a civil lawsuit by the victim's 35th birthday, or within 3 years of the date the victim discovered or reasonably should have discovered that the injury was caused by the sexual abuse, whichever is later. The law also provides for treble damages and the right to sue institutions that covered up abuse. Additionally, the criminal statute of limitations for certain child sex offenses has no time limit under Wisconsin law.
Does Wisconsin have a statute of repose?
Yes, Wisconsin has several statutes of repose. The most significant include: (1) Medical malpractice — a 5-year statute of repose under Wis. Stat. § 893.55 that bars claims filed more than 5 years after the negligent act, regardless of discovery, with exceptions for foreign objects and claims involving minors; (2) Construction of real property — a 10-year statute of repose under Wis. Stat. § 893.89 for claims arising from the construction or improvement of real property; and (3) Products liability — a 15-year statute of repose under Wis. Stat. § 895.047 that bars claims filed more than 15 years after the product was first sold. Statutes of repose are absolute deadlines that generally cannot be tolled or extended.
Does making a partial payment restart the statute of limitations on debt in Wisconsin?
Yes, in Wisconsin, making a partial payment on a debt may restart the statute of limitations. Wisconsin courts have held that a partial payment can constitute an acknowledgment of the debt and restart the limitations period. This applies to both written and oral contracts. If you are contacted about an old debt, consult with an attorney before making any payment or written acknowledgment, as doing so may revive a time-barred debt.
What is the criminal statute of limitations in Wisconsin?
Wisconsin has no statute of limitations for 1st-degree intentional homicide, murder, and 1st-degree sexual assault of a child. 2nd-degree reckless homicide has a 15-year limit. 2nd/3rd-degree sexual assault has a 10-year limit (with 1-year DNA extension). All other felonies have a 6-year limit. Misdemeanors have a 3-year limit. Crimes against children have extended limits (before victim turns 45 or 26 depending on severity).
What happens if I miss the statute of limitations deadline in Wisconsin?
If you miss the deadline, the defendant can file a motion to dismiss, and the court will almost certainly dismiss your case permanently. Wisconsin courts strictly enforce these deadlines. Very few exceptions exist, so it is critical to file before the statute of limitations expires.
