No, they do not have anything to do with the maternal side as they blame our son for the break up of the marriage and for their daughter being alcholic. Our family are disgusted with our son's behaviour and would not intervene and wife no.2 does not have contact very often with her own mother as she lives in newcastle-upon-tyne, and she only has a aunt as her real father is in a home.
I do not think that calling in a mediator at the moment is a very good answer to the question and extra information I have supplied you with. I want to know how we stand in law and the best and quickest way to see our grandchildren again. At what age can they decide who they want to live with?
