What Technology E&O Insurance Requirements Apply in Wisconsin?

Wisconsin Statutes section 895.447 voids a provision that limits or eliminates tort liability as part of a contract for the construction, alteration, repair, or maintenance of a building, structure, or other work related to construction, including moving, demolition, or excavation. The section does not apply to an insurance contract or a workers’ compensation plan, and it does not apply to a contract entered into before July 1, 1978. Section 895.045(1) then allocates a negligence injury: recovery is allowed when the claimant’s negligence was not greater than the negligence of the person sued, a person under 51 percent of the causal negligence pays only that percentage, and a person at 51 percent or more is jointly and severally liable for the damages allowed. Parties in a common scheme are jointly and severally liable under subsection (2), except as section 895.043(5) provides.

What Is Tech E&O Insurance?

Technology errors and omissions coverage can help pay when a customer claims your software, hosting, installation or technology advice caused financial loss. If you provide tech products or services, check each activity; cyber incidents and unrelated professional work need separate review. Read the national Technology errors and omissions (E&O) guide.

What Should You Watch for With Tech E&O Insurance in Wisconsin?

A building-systems contract cannot sign away tort liability
Section 895.447(1) reaches any contract, covenant, or agreement relating to construction, alteration, repair, or maintenance of a building or structure, or other work related to construction. Controls programming, commissioning, and installed-system work that is part of that contract sit inside the sentence. A clause that says the integrator is not liable in tort for bodily injury or property damage from that work is against public policy and void. A standalone software license that has nothing to do with construction is outside the section’s stated subject. ¹
The statute does not void the insurance contract itself
Subsection (2) says the section does not apply to any insurance contract or workers’ compensation plan. An E&O or general-liability policy is not struck down by 895.447. What the section strikes is a construction-contract term that tries to eliminate tort liability. Buy the policy for the liability the construction contract cannot waive, and read the policy’s own professional-services and faulty-workmanship terms. ¹
Fifty-one percent of causal negligence makes the share joint
Section 895.045(1) measures the plaintiff’s negligence separately against each person found causally negligent. Below 51 percent, liability is limited to that percentage of total causal negligence. At 51 percent or more, the person is jointly and severally liable for the damages allowed. Subsection (2) adds joint and several liability for a common scheme or plan, notwithstanding subsection (1), except as section 895.043(5) provides. Use this statute for a negligence injury. It is not the measure of a pure unpaid-fee dispute. ²

Which Tech E&O Insurance Providers Have Wisconsin License Records?

These providers publish a national listing for Technology errors and omissions (E&O); the license records below name the licensed entities and roles. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Wisconsin. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

Specialty Program Group LLC
TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. ¹³

Its separate surplus-lines table includes Idaho number 870820, while a footnote says Georgia and Idaho do not issue agency-level surplus-lines licenses.

The page is company-reported and does not establish product availability. ¹⁴
