A relative who has never lived at our house is in the habit of falsely using our home address as their place of residence whenever disclosing their place of residence for legal purposes, rather than using their own.
Additionally, this relative is the family wastrel/black sheep/prodigal child, and is intentionally using our address in order to avoid the consequences of their bad behavior, and as a result, we receive bills and other legal documents intended for this relative, but what is more troubling, we also receive visits from debt collectors and officers of the law who are looking for this relative. We cannot even tell these people where to find our relative, as they know that we will not help hide them, and so we are not told the relative's current address or other contact details.
We are in the position where this relative's actions have become intolerable, but asking the relative to correct their residential address registration with all entities where our address has been falsely substituted has been refused - apparently our discomfort is amusing to our prodigal relative.
We are at the point where this relative has destroyed any shred of affection that we may have had for them, and we are prepared to apply the full force of the law in order to have this situation corrected, no matter how negatively it may impact our relative.
We and our relative live in Victoria, Australia, so what laws of that jurisdiction may we reasonably expect to be able to use to redress this situation?
Ideally there would be some criminal matter with which we could have our relative charged, since we do not have - nor do we feel that we should have to expend - the financial resources necessary to protect ourselves from our relative by bringing a civil suit.
