DCF stands for Department of Children and Families. Depending on where you're located, they may also call themselves DCFS (Department of Children and Family Services) or CPS (Child Protective Services. No matter what combination of letters they're using, there is usually only one reason that you might find them at your door – someone called them and reported that one or more of your children was being neglected or abused. This can be a harrowing experience for any parent, particularly one who's not guilty of any wrongdoing.
Whether you've recently been charged with a DUI or not, it's a good idea to be aware of your rights during a DUI investigation. In the event that you have been charged with a DUI, hopefully you've already begun speaking with DUI defense lawyers in your area. More than likely, a good lawyer will start by trying to determine whether the arresting officer made any mistakes during the investigation that could result in the prosecution reducing or even dropping your charges altogether.
