A parent who refuses or neglects to allow an ex-spouse to spend time with their children could lose his or her driver's or occupational licenses.
According to the US Dept. of Health & Human Services study, "Survey of Absent Parents" over 60% of mothers regularly violate the access rights of fathers, cutting off all contact between the children and their fathers within five years. Unlike child support, mothers are not jailed, even with multiple Contempt of Court ruling against them for violating the fathers' court ordered visitation rights.
