The clause in the deed is any litigation arising on future by way of minors would be solved by those who had signed.Now the son of first son of the deceased (grand son) has filed a complaint making me as 4th defendant claiming his share in the sold property as he his having his right as it becomes ancestral propetry.Also hi says he was minor when the transaction took place.Now he is 19 years old and his father was adicted to drinks he sold the property. he wants his share.
