You can always make an abuse report. but depending on the situation the report may not be acted on for example the child may have grown up. (statue of limitations is that the abused must report within a certain timeframe after remembering the abuse..) , or the person that did the abusing got help and is no longer abusing, the person who abused may still be in the other parents life but has moved out of the home and no longer has contact with the children, Also many times an abuse situation has happened but there is no proof -too much time gone by no bruises and children say nothing happened so children services are unable to do anything. Basically in order for the abuse report to be acted on and prosecuted there must be proof (recent bruising and so forth) and testimony from more than one source that they witnessed (were there during the abuse) the abuse. otherwise the children will be given back to the parents. The states cannot tell someone who they may date and who they can and can't live with. Here in the states the mother can date or live with this guy if she chooses. If there is proof the person who makes an abuse report and upon investigation the proof turns up the person who reported must testify in court because here in the states anyone under arrest and prosecution has the right to face their accuser during trial unless the accuser is a child and then in certain situations the judge interviews the child and decides if the child can testify on tape instead of in the court room.
