I worry about my son’s safety when he is with his dad

What is it that is worrying you? If your worries are about whether he is having junk food, staying up too late, not following your parenting rules then maybe you need to accept that the two of you parent differently. However, if your son is being neglected (left alone when young, not fed enough or dressed warmly) or is in danger (not being in a car seat when in a car, exposed to inappropriate situations e.g. dad takes drugs or drinks heavily during his parenting time) you must take action immediately. Whilst a relationship between father and son is to be encouraged, your son’s safety is your absolute priority. Seek legal advice and get the solicitor to write to him detailing why contact is being denied. It may be the situation can be resolved or it may be that he will go to court and end up with only supervised contact. You can find information about local low-cost legal assistance at the CLS website
