We have consent orders that word 'both parties are at liberty to communicate with the child by telephone each alternate day when the child is not in their care'. Our son is 6 and has been in a shared arrangement since he was 1 1/2years (custody of children). Our question is, if on the alternate day we are not available (for the other party to make contact), or wish to spend a weeks holiday uninterrupted by the other party unless an emergency, what are our obligations under family law to be 'on-call' every other day ?
