Does anyone know at what age a young person can decide who they go to live with please? I am the step-mum of a 12 and 14 year old..soon to be 13 and 15 year old. There is a court-order in place that states they spend x consequentive days with their dad and then x with their Mum. But at what age do they get to decide for themselves who they want to live with...if that's the path they choose? Thanks.
