4:39-1. Special Verdicts
The court may require a jury to return only a special verdict in the form of a special written finding upon each issue of fact, in which case it may submit to the jury either written questions which can be categorically or briefly answered or written forms of the several special findings which might properly be made under the pleadings and evidence; or it may use such other method of submitting the issues and requiring written findings thereon as it deems appropriate. The court shall instruct the jury concerning the matters submitted as is necessary to enable it to make its findings upon each issue. If in so doing the court omits any issue of fact raised by the pleadings or by the evidence, each party waives the right to a trial by jury of the issues so omitted unless before the jury retires submission to the jury is demanded. The court may make a finding as to an issue omitted without such demand, or, if it fails to do so, it shall be deemed to have made a finding in accord with the judgment on the special verdict.
