Did you provide a good address on the summons? The process server will only serve at the address provided to him or her. Yes, your ex can be served at his place of employment but he will need to be personally served and not through substitute service. You should check with the process server you used.
It depends if it is truly uncontested which means you both agree on how you two will settle your divorce. If your husband agrees and will sign the marital settlement agreement and parenting plan, most attorneys charge a flat or reduced rate as the case will settle with no litigation. The problem arises when you tell your attorney that it is uncontested but it turns into a contested matter and you end up paying for a contested case as most divorce attorneys charge by the hour. Good luck.
You and your father should file a declination of prosecution with the state attorney's office so they know your position on moving forward with the case. Also, speak to your husband's criminal defense attorney on how to properly move forward in the criminal case if it is filed by the state. The attorney can explain subpoena powers of the court and your obligations moving forward.
You stated you had a lawyer. You should ask him/her the questions that you have if the lawyer is indeed representing you. You can be charged with filing a false police report if law enforcement has proof that you did this. Do not discuss this with anyone but your lawyer so you are advised properly.
Was this a trial? Was it recorded? Did you ask to present your case? Did you guys run out of time? Although the Judge has discretion to hear the evidence and rule, I would take the transcript if there is one to an attorney who practices appellate work to see if you have grounds for an appeal or you can see if you have grounds to motion for a rehearing.
You can move to dissolve the injunction but remember that if there are any violations or the petitioner has reason to be in continued fear, the court may not dissolve it. Contact an experienced domestic violence attorney to assess your case in your area.
You can request retroactive support to the date of separation in the pleadings you file (petition for dissolution of marriage with children).
You can call the local bar association to see if they offer some type of modest means program or call a local legal aid society to see if they will handle your case. If you genuinely believe your child is in danger and being abused, you can call the department of children and families or law enforcement.
Are there any witnesses to the fight with the women in the park? I agree that your lawyer (if you have one) should take a deposition of the alleged victim. I suggest hiring an experienced criminal defense attorney in your area to handle your case.
The state can still go forward without your cooperation if they have enough evidence to proceed without you (i.e., other witnesses, admissible hearsay testimony, photos, videos, admissions, etc.). I agree with the other two attorneys as well.
