Three procedures, one $50,000 line
Wisconsin offers three separate simplified alternatives to full probate, all built around a $50,000 threshold: Summary Settlement (net value, requires a surviving spouse, domestic partner, or minor children; the court settles the estate directly, no personal representative appointed), Summary Assignment (net value, used when Summary Settlement doesn't apply because there's no such survivor; the court assigns the property to those entitled to it), and Transfer by Affidavit (gross value, presented directly to asset holders, under Wis. Stat. §867.03, no court involvement at all).
Real estate: excluded from the affidavit, murkier for the other two
Transfer by Affidavit explicitly does not cover real estate. Summary Settlement and Summary Assignment run through the court, so a house-inclusive small estate should be confirmed directly with the Register in Probate rather than assumed either way.
Marital property shrinks the practical question
Because Wisconsin's marital property system already gives a surviving spouse outright ownership of their own half of marital property, only the decedent's own share typically needs to pass through one of these three procedures — often making a "small" estate genuinely small in practice.
Statewide thresholds, 72 counties
Milwaukee, Dane, Waukesha, and Brown County among them — the $50,000 figure and the three-procedure structure apply identically statewide, filed with the local Register in Probate.
