What legal action can a co-owner take if they cannot agree on a method to dissolve the tenancy?

A partition suit is a legal action that allows a co-owner of property to seek a court's intervention when they cannot agree on how to dissolve a tenancy or divide the property. This can occur in situations where co-owners are unable to agree on whether to sell the property, buy each other out, or otherwise resolve their shared interest. The suit enables the court to determine how to fairly divide the property or arrange for its sale, ultimately leading to a resolution that allows co-owners to exit their joint ownership.

In contrast, options like joint agreement require the consent of all parties, which may not be feasible when there is a disagreement. Community claims and default dissolution are not recognized legal actions for resolving disputes among co-owners in this context. Thus, the partition suit stands out as the correct answer for those needing a legal remedy in scenarios of disagreement among co-owners about the dissolution of their tenancy.
