My brother creats problem in my house construction

If the property is your without any dispute and you have approved site plan and map from the concerned muncipality or the department having jurisdiction over the area to approve and allow constructions, then non can stop you.

However if un-necessarily someone causes you truoble just file a complaint with police and or get an injuction from court making the disturbing guys party to retrain them from csausing interfarance in your matters.
