Where the claim has been filed by the creditor he is precluded upon the hearing of the claim to demand a judgment for an amount greater than that specified in the claim itself. It is the duty of the court to examine every claim that is presented and upon approving of the same to render a judgment which shall draw interest at the rate fixed by statute until the payment of the same. There is no particular form used or required in the rendering of such a judgment in a court of probate.
