I am willing to wait
I suggested that I was happy to relinquish my share of the main property in exchange for the rear lot that the apartment block is built and have the two separated with two separate titles.
From my prospective since they did not contribute to the flat's construction they are essentially only losing the empty back yard and gaining a 33% stake in the main building worth far more
As expected they refused this offer,because their target is the apartments anyway. Selling outright means I lose my investment and my partners don't get their investment back whilst my brothers would essentially get a 60% slice of the apartments.
So as I said it is basically a case of extortion and I wanted to know if I could find any legal protection to force them to come to a mutual and fair agreement that does not leave me facing huge liabilities
