"If you are found guilty, after that is the sentencing phase. During the sentencing phase, the judge may determine you adjudicated guilty of the crime, which means you are convicted for that crime in a court of law. Adjudicated means the act of pronouncing or declaring by a judge."
"If the Judge withholds adjudication of guilt, it means you have not been formally found guilty of the crime and there is no conviction. It is possible to plea guilty to a crime but still receive a withhold of adjudication and thus, not be convicted of the crime. However, for punishment, the Judge can still order you to probation or other sanctions."
