Let me guess, TNIP: You reckon the respective percentages of effort put into the build determines the respective ownership percentages of the aircraft. Are you sure you’re not joint owners? No doubt there’ll be a detailed agreement setting out the ownership arrangements...
So far you’ve managed to defame the other owner, throw your insurance under the bus and devalue the aircraft.
Partnerships that go pear-shaped are a very rich vein for lawyers. Not so for the estranged partners.
Much of the damage done by this thread has already been done, but I’d suggest you consider deleting it.
