Is it a violation of parental rights to have an order restricting a parent to initiate contact with minor children when with the other parent

The issue raised is an age old problem; how much access should the other parent have while the children are placed or in the care of the other parent? There is no easy answer or law to address your question. I think it is common sense that prevails. If you call the children 10x a day when they are with the other parent, you are overstepping your bounds, particularly, if you are the primary parent and they are simply with the other parent every other weekend, by example. If on the other hand, they are with the other parent for extended periods of time, such  as several days in a row or week on week off placement, it would not be unusual to have some type of limited phone contact with the children while in the care of the other parent. I certainly wouldn't advise you to sign any agreements that limits your contact with your children. Are they willing to sign a reciprocal agreement that they have no contact with the children when they are in your care?
