Dh and BIL now own a holiday chalet. MIL purchased it before she died as she felt both brothers and their families would get lots of great holidays at the accommodation
As the site fees are expensive both BIL and to a lesser extent dh want out. Selling looks tricky so BIL is trying to convince dh to buy him out.
Dh is seriously considering this but is saying that he will give his brother x amount to buy him out but no mention of sorting it out legally. Aibu to be wary.
