Property issue

Experts kindly answer my query.we four brothers have got property registered on our names which we got through a family settlement.we all share a common passage through which our drainage lines run.now I want to dispose my property.one of my brother is saying that since we share a common passage preference to buy the property must be first given to them and if I try to sell to someone outside he will obtain a stay from the court.is that possible.kindly help
