Wisconsin allows estates under $50,000 to use a simplified small estate affidavit procedure, which is a form rather than a court case and typically doesn't require an attorney. For larger estates, formal probate is involved enough that retaining counsel is usually practical — the procedural work is what they're there for. Use the Wisconsin probate calculator to estimate the costs.

In Wisconsin, the situations where retaining counsel is typically worth the cost are: blended families with children from prior relationships (community property rules can produce surprising outcomes); ownership of a business, rental property, or significant investment assets; special-needs dependents who need a special-needs trust to preserve benefits; substantial property held in multiple states. If none of these describe your situation, the simpler online and DIY tools are often enough.

Ask up front whether the firm bills by the hour or by flat-fee package, and what the expected cost is for your situation.
