Ma Grand Father and his 3 brother made a contract in 1967 that if any of one will sell his property to any one outside from family he will deliver a notice to his brother first, but since in 1968 they breach this Contract and no one filled a suit in Civil court.
Later on in year 2005 when I was willing to sell my portion of property my cousin filled a Civil suit against me that our Grandfather had a contract like this..
Can you give me any Ruling that this type of Breach when it is proved that its broken since 1968 will not apply ..
