First, I am assuming that you have already plead guilty because you are talking about appealing your case. With this as the premise, your avenues of appeal are very limited. I would suggest speaking with the attorney who represented you at the guilty plea. If you represented yourself, you should speak to an experienced criminal attorney in your area right away. Understand that appeals and other post sentence motions are time sensitive, meaning, they must be filed within a certain number of days after the sentencing. Once this date is past, you may be without recourse.
Best of luck,
Coley O'Brien Reynolds, Esquire
