Colloquy (law)
In law, a colloquy is a routine, highly formalized conversation. Conversations among the judge and lawyers are colloquies. The term may be applied to the conversation that takes place when a defendant enters into a plea bargain and the judge is supposed to verify that the defendant understands that he is waiving his right to a jury trial.
In criminal court, a colloquy is an investigation within a defendant's plea to reassure that the plea was given "knowingly, voluntarily, and intelligently". The defendant needs to understand the charges against him, the penalties that he will face, and his rights before entering into a guilty plea. In the US, that includes describing the rights guaranteed by the Fifth and Sixth Amendments as well as a caution that non-citizens who are convicted of crimes risk expulsion from the country.
A defendant who denies guilt may still "plead down".
