If your parenting time is denied, ALWAYS send the Denial Of Visitation form letter. Copy your attorney, opposing counsel, and the court clerk on this letter.
File a police report to further document the denied time. The police may be
reluctant to file a report and tell you that it's a 'civil matter'. Insist (politely) that they file a
report anyway.
After a few denied visits, file a contempt charge in court against the custodial parent.
Use the letters, police reports (if any) and the Parenting Time Tracker to show that you
were denied your parenting time.
