Guidance on owning or leasing an aircraft
Aircraft are regularly bought and sold like any other item. For an aircraft on the UK-register anyone selling an aircraft must inform the CAA immediately. If the aim is to maintain the aircraft on the UK-register then the new owner must apply to the CAA to re-register it. The UK-register is not a register of legal ownership.

The situation in which the charterer is another air operator that has its own operating authority and charters the entire capacity of the aircraft, usually at short notice, is termed a sub-charter
