 Parties may amend any defect, mistake or informality in the pleadings or other parts of the record or proceedings. When either party supposes that in any part of the pleadings he has missed the ground of his plea, and that he can plead a different plea that will save him in his cause, he may change his plea, answer, replication or rejoinder, as the case may be, and plead anew, and the other party shall have reasonable time to answer the same; and, in any case when a party amends or alters any part of the pleadings or pleads anew, if it occasions any delay in the trial or inconvenience to the other party, he shall be liable to pay costs at the discretion of the court. Any court may restrain the amendment or alteration of pleadings, so far as may be necessary to compel the parties to join issue in a reasonable time for trial.(1949 Rev., S. 7852.)See Sec. 52-72 re amendment of process.Amending records after term. 4 C. 77; 15 C. 37; 21 C. 530; 25 C. 342.
