 The topic we are going to talk now is the need of the mental health professionals in legal system. Since we know that at times we heard in forensic psychology there comes the stage when we have to have align the need of the mental health professional with the legal system. Mental health and behavioral social professionals have increasingly found themselves involved with the legal system as being expert and as being dependent. So their needs are very much present in different scenarios which we will talk about now. Forensic psychologies and emerging field and forensic clinicians have important role as experts, witness or consultants for many different type of legal matters. Now you see while conducting forensic mental health assessment which is very much present, the practitioner must be especially careful while trading into legal system as they are about to enter philosophically aligned territory because there are some complications of legal system which as long as a forensic psychologist doesn't study properly it becomes very difficult to intervene into them and you may not be able to understand the legal system as long as as a forensic psychologist you don't study those legal complications you don't develop an acquaintance with it and then you can see that how you can play your professionally equipped role into that system. Legal lands may arrive for mental health evaluation along at least three different roles. Now those people who are a part of any legal case can come from those three reasons with their cases to mental health professionals. First, some legitants may come for evaluation under a court who is sent to court and he says that you should see for example to assess the defendant's competence to stand trial or often guidance in a child custody case. First of all, it seems to be simple but rather it's not that simple to determine that either a person is mentally able enough to do anything or not or the person who has come for a case is mentally mentally insane or not. Or if a child's custody case alleges that this parent is not mentally fit to take care of a child then in that case it may be necessary to assess and see the mental health status that either he is mentally able enough to do a child care or not. Secondly, some are sent by their lawyers seeking an assessment for their mental or emotional state relevant to a potential claim or defense. Sometimes to save yourself from some situation to take this claim that I am not mentally well that's why I have committed to describe. So this can be used for your own defense. Valuation related to potential insanity defense. This can describe insanity defense in such a way that a lawyer says that you have this provision in law that if you could do this crime in that form then you could have said that you are mentally stable. So in those situations people come to get assessment because they need that insanity defense. Then third, the parties may agree to have a legitimate evaluated in the absence of a court order. For example, in many civil and in many criminal cases the parties understand that the opposing side has a right to an evaluation conducted by their own experts and informally agree to do so. Because if you have a case in which two parties and one of them has made an assessment then the other party has a right that they can go for their own assessment. So basically to give someone a counter narrative to prove that your assessment is not correct then the other party can also get an assessment out of the court. So these are the basic three types of the reasons because of them the legally related cases can come to the psychologist for an assessment but for all of these it's very important that the person should have a complete knowledge of legal procedures and he should must have training in forensic psychology.
