Hi Clare - Thank you for responding to my rambling question!
I'm afraid we have no idea how much her father earns; things have progressed slightly since in that my daughter has referred the matter to CSA. My granddaughter has also text her father to say that she does not wish to visit him this weekend in light of how he has and may react towards her. He insists that he will pick her up on Saturday and that his word is final on the matter.
Our granddaughter does seem to enjoy the time she spends with her father but is very wary of saying or doing anything that may make him angry (her words) and this latest refusal to visit him is, I think an indication of that.
No, there isn't a court order in place.
Thank you Clare - really helpful. Just one thing, I have passed this info on to my daughter and she tells me that there is a court order in place regarding access. My granddaughter's father is allowed access alternate weekends. Apologies for this oversight on my part.
