When several partners or joint contractors bring or defend an action as such, any one of the partners or joint contractors may enter an appeal in the name of the firm or joint contractors and sign the name of the firm or joint contractors to a bond if required by the superior court, which shall be binding on the firm and the joint contractors as though they had signed it themselves. In the case of corporations, the appeal may be entered by the president or any agent thereof managing the case or by the attorney of record.
