Who inherits if there is no will and no heirs in Switzerland?

If there is no will and no legal heirs in the federal order of heirs, the estate passes to the canton. In some cantons, a share also goes to the municipality. The exact split and process are set by cantonal inheritance rules and local procedures.

How is an intestate estate shared in Aargau?

When there are no heirs and no will, Aargau law allocates two-thirds of the estate to the canton and one-third to the commune of the last residence. This apportionment is specific to Aargau and can differ in other cantons of Switzerland.

Can a will prevent the canton from inheriting my estate?

Yes. A valid will lets you choose beneficiaries within Swiss inheritance law, which protects forced shares for close family. If forced heirs exist, they receive minimum shares. Absent heirs, your will directs the estate, avoiding escheat to the canton and municipality.

What should investors watch after municipal windfalls?

Assess whether the windfall is treated as one-off income, how it affects cash and net debt, and whether proceeds fund non-recurring projects or reserves. Normalize operating margins by excluding the gain, and review transparency around timing, accounting classification, and use of funds.
