Nagano-Miyake Compact

The Nagano-Miyake Compact of 2153 is a legal document signed by the main galactic powers that states that any derelict space vessel or other items from one government can be claimed by an individual from another government if the item is found in spatial territories not claimed by a signatory government.

In 2269, attempted to use the Nagano-Miyake Compact to solidify his claim to a  that he had stolen from a Klingon agricultural colony planet.

USS Enterprise (NCC-1701) chief engineer correctly noted that the Compact only applies to spatial territories not claimed by signatories. (: )

In 2380, USS Yagami (NCC-78334) helmswoman Irina Nielsen correctly quoted the compact to give ownership of the USS Enterprise (NCC-1701-B) to Stargazer Seville and her friends and allies, following the destruction of their original vessel.
