The first step is to file a Petition for Dissolution of Marriage. In your Petition, you can request that the Court award you the majority of overnight visits and establish a timesharing schedule for your husband. You can also request that, at least initially, any time your child spends with his father be supervised. It is important that a child spends time with both parents but your child's well being is the most important factor to the Court. Once a Petition has been filed and you have an open case in Court, you can file a Motion for Temporary Relief and request that theCourt establish a temporary timesharing schedule during the pendency of your case. You can also file a Motion asking the Court to require you Husband to submit to random drug testing.
