During a child custody investigation, the investigator may conduct surveillance to get a better idea of how the parent treats his or her child when he or she does not know about any monitoring going on. Private investigators may document any instances of abuse or neglect by taking pictures or making audio or visual recordings of the parent interacting with the child. Some of the elements that a private investigator may try to include in his or her surveillance include reckless driving, criminal activity, gambling, drug abuse or other activities that may have a negative impact on the children. Additionally, the investigator may look for any signs that the parent is not providing a safe and hygienic living space, food or necessities.
