It is important to obtain some independent legal advice in relation to your situation. A lawyer can help you understand your legal rights and responsibilities. They can also explain how the law applies to your case. A lawyer may also be able to help you reach an agreement without going to court. The court is unable to provide legal advice because to do so could seriously compromise the court's ability to impartially determine a case if a person then applies to the court seeking orders.
