Good for you. You and your ex were able to exchange material and so fourth, but unfortunetely, NOT everyone is able to do this and as everyone knows being common sense, every situation is different. First, the Judge at the Case Conference wrote an order for the SIN NOT to be given to my ex and yes the children were minors at the time; Second, there was a restraining order and criminal charges with jail time; third, my laywer has had the children's SIN from the beginning; fourth, a different judges made an order for the chidlren's school and address to be obliterated, and this was the OCL lawyer who requested such. I wasn't in court for that motion but the judge must have had a good reason for this, don't you agree? Keep in mind Judges have to be a lawyer for at least 25 years before becoming judges, I am sure they have seen every case possible; Five, there is also an order for him to provide me with his address, telephone number, email address and not the opposite. Hum..I wonder why that is?? He had supervised access at the center which THEY cancelled as the visits didn't go well (I wasn't there and between the OCL lawyer and the center); Six, it has been dragging on for years and not because I was uncooperative like you say, but because he left for Jaimaica in the middle of a assessment ordered by the courts, and while the matrimonial home was for sale making it very difficult to deal with issues. It is so easy for one like you to talk and make your own assumption thinking it is always the other parties fault. Before making assumptions, and false accusations, I would take a good look at the whole pictures. My question was for someone who knows why ones needs the children's SIN especially since there is a Court Order not to provide it directly to him? same with asking for the children's birth certificate, and passport??
