Did you have legal counsel helping you reach that settlement? If so, that is the place to start. If not, reach out to a local personal injury attorney and let them know you can pay them a flat fee to resolve all of the outstanding bill issues -- an experienced attorney can probably negotiate payments that will leave more of the dollars in your pocket.
As if that matters . . .
Again, I am so sorry.
In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but insted need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice. If you want to be completely sure of your rights, you must sit down with an experienced criminal defense attorney to be fully aware of your rights.
