DS is separated from the mother of his DS, and she's being akward. He's been paying child maintenance at well over CSA rates since they split, but he's been giving her cash, so there's no evidence. He'd now like to pay maintenance in a "proveable" fashion, and obviously it would be best if he could pay directly into her bank account. It is likely, however, that she will refuse to provide this information. Can he open an account in his DS's name (child is 2yo), pay maintenance into that, and give her a card to access the money? (Scotland, if that makes any difference.)
