Yes, but HIGHLY unlikely. In a civil case the state is under no obligation to spend the taxpayers money to transport and guard the incarcerated individual involved in a civil trial.
The question is not worded clearly. If the questioner already HAS counsel and wishes to discharge/fire them, all he has to do is either do it in open court while on the record, or file a motion with the court notifying the judge that they are proceeding pro se. If, right from the outset, they are not engaging counsel, that fact will be included in the information with the court filings for the case. The judge will probably strongly counsel you to retain counsel, but you DO have the right to represent yourself if you wish. Please remember the old lawyer adage: "The man who represents himself, has a fool for a client."
In a criminal case, through the public defender or appointed by the court. In a civil case, you can try legal aid or a local pro bono project, but there is no guarantee.
"Leave to proceed" typically refers to obtaining permission from a court or authority to continue with a legal proceeding or action. It is required in certain situations before a case can move forward to the next stage. Without leave to proceed, the case may be stalled or dismissed.
No, you are not. The Sixth Amendment of the Constitution declares that "In all criminal prosecutions, the accused shall enjoy the right to . . . have the Assistance of Counsel for his defence." There is nothing similar for civil case.
Good question. 90% of all civil cases are settled without a trial.
No. Retaining legal counsel would not change the outcome. Either you were insured or you were not.
Not likey. In a case where there is no evidence or witnesses it turns into a he-said she-said battle.
Not in a criminal case. In such cases the prosecuting attorney represents all of the people of the state and/or country and therefore represents the orignal plaintiff/victim. A civil trial is basically the same, if the plaintiff has legal representation. For example, a credit card company sues for debt owed. It is understood that the CC's legal counsel if the plaintiff by proxy and has the right to "prosecute" the case. If the civil suit has been brought by an individual plaintiff representing themselves, he or she must be present at the time of the trial or the case will be dismissed (generally w/o prejudice). Likewise, if legal counsel does not appear the case will be dismissed.
I do believe that is possible but you should save anyways just in case.
There is no single answer to your query. It depends on the severity of the fraud and the judgment of the court where the case was adjudicated. You should call your attorney for advice if you were represented by counsel. If not you should visit the court, bring your evidence with you and and get some advice from a clerk about how to proceed.
