When a party interferes or violates the other party's parenting time – if a party has every other weekend, for instance, and the other party leaves town and the party whose time it is is unable to exercise their parenting time, or if there's a holiday and they're unable to celebrate with the children – that would be a violation in parenting time interference. Or it could be as simple as calling the other parent while they're with the children incessantly once an hour – that would be interfering with their parenting time.
When a party interferes or violates the other's parenting time, there are certain punishments like make-up parenting time or court-ordered counseling. There could be fines or reimbursement for attorney fees in seeking punishment for the violation of the parenting time. But again, the attorney will speak with the client about how extensive is it. Is it to the point where it's not in the children's best interest or endangering the children? Or was it a one-time occurrence that couldn’t have been avoided and there's a balancing act.
