This is more-than-likely a misdemeanor offense. If this was a Metrolink ticket, then it will not have any substantial impact on your ability to secure employment. It is always best to contact an attorney but if you need additional time to talk to (or hire) an attorney, make sure you appear in court and explain that to the judge.
This really depends on what your charges were. An SIS is a non-conviction, so if you successfully completed your probation you should look into whether a non-conviction of your charges will prevent you from getting the job(s) you are looking for.
This likely on whether she has signed the release and the settlement check. The Attorney is likely going to need her signature on the settlement check when it arrives so that lawyer cannot get paid without meeting with her again and having her endorse the check. If she is having second thoughts she needs to contact the attorney ASAP
The Court always rules based on the child's best interests. There has to be a substantial change in circumstances suggesting that a modification of the visitation/custody order would be in the child's best interests.
If the non-custodial parent is not paying court ordered child support this matter can and likely will be addressed by the State via criminal proceedings. Non-payment of support is a criminal matter and the state will do everything possible to ensure that the current support and arrears are being paid. Child support is actually still enforceable if the children enroll in college full time after high school regardless of their age. I would contact FSD to discuss these concerns.
The state has unfortunately decided to step in and take control of the situation. Even though the mother does not want the state to prosecute, it is ultimately up to the State whether they prosecute you for criminal non-support. You should have the mother contact the prosecuting attorney and the Family Support Division office and inform them that she would like to waive a specific amount of the back support owed. You should contact an attorney as soon as possible to discuss this matter in detail.
Your son's mother can contact the Missouri Family Support Division and/or the prosecuting attorney for your case and inform them that she would like to waive a specific amount (or all) of the amounts owed in back support. You should obviously contact a criminal defense attorney to discuss details of your situation.
