Hello and welcome to JustAnswer. Please note: This is general information for educational purposes only and is not legal advice. No specific course of action is proposed herein, and no attorney-client relationship or privilege is formed by speaking to an expert on this site. By continuing, you confirm that you understand and agree to these terms.
1) Do I need legal representation to do this, or can I do this by myself?
You are not mandated to have an attorney. However, an attorney is highly recommended, because the procedural steps are complicated. Thus someone filing pro se (without an attorney) are often just as likely to hurt themselves as to help themselves.
2) If I do need legal rep, how much would it usually be to get something like this done.
We are talking about a criminal non-disclosure, correct? Anywhere from $1,500 to $5,000, depending on the situation.
3) How hard is the process to get this completed and how long will it take?
The process itself is not that long. One has to draft the petition, file it with the Court, serve the District Attorney's office as well as the P.O. (if there was one), and then set this for a hearing with the Court. Then one has to show up to request the relief in person from the Court at the oral hearing. The crux lies in proper drafting, filing, and other procedural steps which are difficult and nuanced.
