I have been separated from my spouse for 30 years total, but she probably will contest it.
Criminal Defense Attorney
In Pennsylvania a "no fault" divorce may be established without the consent of both parties. The party who files a divorce under the "no fault" section of the Divorce Code, must allege that the marriage is "irretrievable broken." Irretrievable breakdown means that the parties are estranged due to marital difficulties with no prospect of reconciliation. In other words, the marriage is not working out, the parties are estranged, and it does not look like the parties will be able to work things out.
In addition, to irretrievable breakdown, the parties either must both consent to the divorce OR must have been seperated for a period of two years or more. Thus, if a husband and wife have been seperated for more than 2 years, it is not necessary that both spouses consent to the divorce.
A party who does not have enough money to pay the filing fees associated with a divorce may file in forma pauperis. Typically court houses have an in forma pauperis form, where the filing party lists his or her income information. If the court determines that the filing party has no income (or low income) the court may waive the filing fees.
It is important that you consult an attorney. A divorce may have significant effects/consequences on more than just your marital status. You need to know your rights and obligations throughout the process. I suggest you look for a pro bono attorney to assist you.

An attorney cannot advise you as to what is or is not in your best interest, until after meeting with you and getting more information.

If you are imprisoned, you might very well qualify as in forma pauperis (i.e. little to no income) which would allow the Court to waive the filing fee. You can file a divorce complaint whenever you desire. Since you have been separated for a period greater than two years you need only allege that the marriage is irretrievably broken

You should be able to file for a Master since you have been separated for more than two years. If you have no income, the court may waive the filing fees and/or administrative fees, but you would have to file a Petition. I would suggest that you contact the Legal Aid office in your county and the bar association to see if they can give you a referral.
