When reporting a case, will my identity be divulged to the person whom I am reporting?
No, your identity will not be divulged. When reporting a case you can do this on a confidential and anonymous basis and nobody can identify you. On the other hand, if you decide to identify yourself, the Lands Authority is still committed to honour your confidentiality and will not give your details to anyone.
