Hi, OP. Sending my sympathy, as you find yourself in a horrible situation. Firstly, can I suggest you join the Facebook group “Necessary Family Estrangement”, as the members will be able to offer you support and advice from their own, similar experiences. It can be problematic asking for advice on this subject on Mumsnet, because you’ll receive a lot of replies from well-intentioned people who know very little on the matter.
Grandparents in England have no automatic rights when it comes to access to their grandchildren. However, they are now allowed to apply to the courts to seek permission to pursue access in a legal capacity. When they apply for this permission, it is quite often granted, but then they are faced with having to prove in court that they should indeed be allowed access.
This system was set up due to the number of grandparents being cut out of the children’s lives due to family break up. For example, mum and dad have an acrimonious divorce, and subsequently, mum refuses to allow dad or his parents to see the kids. But that’s not the case in your situation.
For grandparents to be awarded access, they must provide evidence of a previous positive and significant relationship with the child. If they were providing regular childcare access is often granted. It doesn’t sound as though this applies in your case.
My father instructed his solicitor to write to us, setting out his intention to have access to our three children. We had our own solicitor reply making it very clear we would not allow him anywhere near the kids, for various reasons, but mainly because he hates me. We were then left in a sort of limbo while we waited to see if he would go via the courts. We never heard anything further, and as some time has now passed, I’m hoping he has given up.
Unfortunately, I do know of others whose estranged parents have indeed been granted access so it’s not impossible. But from your brief post, I would say it is extremely unlikely your mother would be successful. Wishing you all the best. I’m sure you’re making the right decision for yourself and your daughter. Good luck.
