he sounds like he was being a bit funny with your address situation there, you informed HIS solisitor afterall so i think he had no right to stop access. Have you wondered why all of a sudden he is being funny with you, could it possibly be that he has started seeing someone new and wants to play 'happy families' with her, or could it possibly be that your daughter has said something? either way i think youy need to see your solisitor as it sounds like he is not keeping to his side.
