Legal Question in Criminal Law in Florida

Re: I would like to know what a legal term means/and how to apply it

A 3.850 motion is a motion to vacate set aside or correct a sentence. The motions must be grounded in these terms:A person convicted and sentenced whether custodial or non custodial under sentence of a court of law in Florida, claiming the right to be relieved of judgement or released from custody on the grounds that the judgement was entered or that the sentence was imposed in violation of the Constitution or the laws of the United States, or the state of Florida, that the court was without jurisdiction to enter the judgement or to impose the sentence, that the sentence was in excess of the maximum authorized by law, that the plea was given involuntarily, or that the judgement or sentence is otherwise subject ot collateral attack may move, in the court that entered the judgement or imposed the sentenceto vacate, set aside or correct the judgement of sentence. The motion must be filed within TWO years after the judgement/sentence become final in a NON-CAPITAL case and ONE year after a capital case. This is just a mere glimpse of what a 3.80 motion is all about. To really get more info, and understand what is all about I urge to contact a competent criminal defense attorney, as you son's liberty is in serious risk. GOOD LUCK, hope this helps...
