Law firm mergers have become increasingly common across Wisconsin as practices seek to expand their capabilities, combine resources, and strengthen their market position. But when firms decide to join forces, one critical question often surfaces late in the negotiation process: what happens to existing malpractice insurance coverage?
The answer isn’t straightforward, and understanding how mergers affect professional liability coverage requires careful examination of policy language, coverage structures, and timing considerations.
Understanding Claims-Made vs. Occurrence Coverage
Most legal malpractice policies operate on a claims-made basis, meaning coverage applies when a claim is first made against the insured, regardless of when the underlying incident occurred. This structure creates unique challenges during mergers that don’t exist with occurrence-based policies.
When two firms merge, the surviving entity may face claims related to work performed by either firm before the merger. If Firm A merges into Firm B, and a client later sues over work Firm A performed three years ago, which policy responds? The answer depends on policy language, the specific structure of the merger, and whether proper steps were taken to ensure continuous coverage.
Wisconsin practitioners often assume their existing coverage automatically extends to merged entities. That assumption can prove costly. Claims-made policies typically require specific endorsements or policy modifications to cover successor entities, and these modifications aren’t always automatic.
Successor Liability and Coverage Gaps
Coverage gaps are more common than most attorneys realize, particularly when firms don’t involve their insurance carriers early in merger discussions.
Consider a scenario where two Madison firms merge in July. Firm A’s policy renews in January, while Firm B’s policy renews in September. Without proper coordination, certain periods may lack coverage, or duplicate coverage may exist while gaps appear elsewhere. The surviving firm needs coverage for both firms’ pre-merger work, but standard policy language may not automatically provide this protection.
Successor liability adds another layer of complexity. When one firm absorbs another, the surviving entity may inherit liability for the absorbed firm’s past work. This liability transfer doesn’t automatically trigger coverage transfers. Insurance companies need advance notice to evaluate the risk and determine whether coverage extensions are appropriate.
Some carriers require detailed information about the absorbed firm’s claims history, practice areas, and risk management procedures before agreeing to cover successor liability. This evaluation process can take weeks or months, making early planning essential.
Policy Assignment and Consent Requirements
Most malpractice policies contain assignment clauses that restrict transferring coverage without the carrier’s written consent. These clauses exist because mergers fundamentally change the risk profile that insurance companies originally evaluated and priced.
When firms merge, they’re essentially asking their insurance carrier to cover a different entity with potentially different risk characteristics. The merged firm may handle new practice areas, serve different client bases, or employ attorneys the carrier hasn’t previously underwritten. Insurance companies typically want to evaluate these changes before agreeing to continue coverage.
The consent process varies among carriers, but most require formal notification within specific timeframes. Some policies mandate notification within a specified timeframe (which varies by carrier), while others require advance notice. Missing these deadlines can jeopardize coverage, leaving the merged firm exposed to claims without protection.
Tail Coverage Considerations
Tail coverage, or extended reporting period coverage, becomes particularly important when one firm dissolves as part of the merger process. If Firm A dissolves and its attorneys join Firm B, Firm A’s policy may terminate, potentially leaving gaps in coverage for claims that arise later.
Tail coverage extends the reporting period for claims related to work performed before the policy’s termination.
The question becomes whether tail coverage is necessary when firms merge. If the surviving firm’s policy properly covers successor liability, tail coverage for the dissolved firm may be redundant. However, if coverage gaps exist or if the surviving firm’s carrier won’t extend coverage to pre-merger work, tail coverage becomes critical.
Practical Steps for Merger Planning
Smart merger planning involves insurance considerations from the beginning of discussions, not as an afterthought during closing preparations. Both firms should notify their carriers as soon as merger discussions become serious, even before terms are finalized.
Early notification allows carriers to evaluate the proposed merger and provide guidance on coverage issues. Some carriers may require policy modifications, additional premiums, or specific merger structures to maintain coverage. Learning about these requirements early allows firms to factor insurance costs into merger negotiations.
Documentation becomes crucial during the merger process. Firms should maintain detailed records of all work performed before the merger, including client files, engagement letters, and billing records. This documentation helps establish coverage periods and policy applicability if claims arise later.
The surviving firm should also evaluate whether its current coverage limits are adequate for the combined entity. Merging firms often increases overall exposure, potentially requiring higher coverage limits or additional policy features.
Moving Forward with Confidence
Law firm mergers can create tremendous opportunities for growth and enhanced client service, but they require careful attention to insurance implications. Wisconsin attorneys considering mergers should engage with their insurance carriers early in the process, understand their policy requirements, and plan for potential coverage modifications.
