When there is a disagreement about the ownership of a particular area, it is referred to as a disputed territory. However, there are several synonyms that can be used to describe such areas. One common alternative is a contentious zone, which implies that the dispute is ongoing and unresolved. Similarly, a contested region suggests that multiple parties are vying for control over the land. Additionally, a disputed zone or disputed area can be used to describe a region where ownership is unclear or disputed. Ultimately, regardless of the terminology used, any disputed territory is a complex and contentious issue that requires careful attention and resolution.
