A timeshare (sometimes called vacation ownership) is a property with a divided form of ownership or use rights. These properties are typically resort condominium units, in which multiple parties hold rights to use the property, and each owner of the same accommodation is allotted their period of time. The minimum purchase is a one-week ownership, and the high-season weeks demand higher prices. Units may be sold as a partial ownership, lease, or "right to use", in which case the latter holds no claim to ownership of the property. The ownership of timeshare programs is varied, and has been changing over the decades.
