She needs a lawyer if she is not going to go otherwise she will get a warrant for her arrest. A lawyer can waiver her appearance and appear for her and try and work the case out. Call my office tomorrow if you have questions or want my representation.
The civil demand and the criminal charges have nothing to do with each other so by paying it the charges won't be effected. You should contact the state attorneys office in the county and see if there is a court date or you can check with the clerk.
