A partition suit would be used under which circumstance?

A partition suit is specifically used to resolve disputes among co-owners of property, particularly when those co-owners hold the property as tenants in common. When co-owners cannot agree on how to handle the property—whether it's to sell it, divide it physically, or some other resolution—a partition suit can be filed to legally divide their interests. This legal action allows the court to intervene and make a decision on how the property should be divided among the co-owners. Since tenants in common hold individual shares of the property and may have differing interests or desires regarding it, a partition suit provides a structured legal process to resolve these issues.

The other options address different legal situations: escheat pertains to property reverting to the state when there are no heirs, foreclosure addresses the sale of property due to a mortgage default, and eminent domain involves the government taking private property for public use, often with compensation. These scenarios do not involve dividing interests among co-owners, which is the primary function of a partition suit.
