Two parents split up, neither agrees to the other having custody of the child and either parent could raise the child what happens.
Also if the parent who mostly looks after the child wishes to move to another Country what happens.
To make it more complicated this is not in the UK but I would like to know how UK law would work cause it could be similar here and perhaps european human rights could come into effect.
One parent wishes to go to live in the UK with the child but the other would not agree to this.
