My wife left our house does she have alright to take him overnight without my consent?

Thank you for your question. Based on your question it appears that there is some disagreement over the custody and parenting time of a child. Furthermore, it does not appear that there is any agreement or Court Order addressing the topic. It would be best to see if an agreement can be reached as it relates to custody and parenting time. In the event the parties cannot agree on a custody arrangement, the Court will likely need to conduct a trial to determine custody. Custody is based on a number of factors that take into consideration what is in the child’s best interest. Based on your circumstances, it may be best to best to contact an experienced family law attorney to address your specific concerns.
