Wis. Stat. § 895.06: Recovery of divisible personalty.

When personal property is divisible and owned by tenants in common and one tenant in common shall claim and hold possession of more than the tenant’s share or proportion thereof his or her cotenant, after making a demand in writing, may sue for and recover the cotenant’s share or the value thereof. The court may direct the jury, if necessary, in any such action to find what specific articles or what share or interest belongs to the respective parties, and the court shall enter up judgment in form for one or both of the parties against the other, according to the verdict.
