Parents must always keep each other advised of their home and work addresses and telephone numbers. Whenever possible and unless otherwise stated herein, all communication concerning the children must be conducted directly between the parents (i.e., in person, by telephone, email, text message, communication notebook, a designated third party or co-parenting tool). Absent an emergency, communication should not occur at a parent's place of employment.
