Whose fruit is it anyway? HI

Fruits of labor - Hawaii News - Starbulletin.com:
A neighbor's fruit tree canopy extends significantly into our yard and creates an abundance of work and green waste for us to handle. Often more of the canopy is overhanging our yard (and other neighbors') than the trunk owner's yard. For more than 20 years, the tree owner concurred that the neighbors owned the fruit over their yards. But the owner recently sold, and the new owner seems to feel differently. Any 'right of way' or 'common law' created by long-term previous activity? Who is entitled to the fruit that grows over onto our yard? Considering we have to do the cleanup, it would seem that we should be entitled to some, if not all, of the fruit.
