Partition Claim A partition claim is a legal action filed by one or more co-owners of a property, such as real estate, who seek a court-ordered division or sale of the property when they cannot agree on its use or disposition. This claim is typically used when co-owners have conflicting interests or cannot reach a consensus on how to manage the property. The court's decision in a partition claim may result in the property being physically divided among co-owners or sold, with the proceeds distributed among them according to their ownership shares.
