09. Treasure

Tim came into possession of an old map showing where a purported cache of gold bullion was hidden. Without any authority from the government Tim conducted a relentless search and finally found the treasure buried in a new river bed formerly part of a parcel of land owned by spouses Tirso and Tessie. The old river which used to cut through the land of spouses Ursula and Urbito changed its course through natural causes.

To whom shall the treasure belong? Explain.
