Section 28A. During the pendency of an action seeking a modification of a judgment for divorce, upon motion of either party or of a next friend on behalf of the minor children of the parties and notice to the other party or parties, the court may make temporary orders relative to the care, custody and maintenance of such children. Every order entered relative to care and custody shall include specific findings of fact made by the court which clearly demonstrate the injury, harm or damage that might reasonably be expected to occur if relief pending a judgment of modification is not granted. An order entered relative to care and custody, pursuant to this section, may only be entered without advance notice if the court finds that an emergency exists, the nature of which requires the court to act before the opposing party or parties can be heard in opposition. In all such cases, such order shall be for a period not to exceed five days and written notice of the issuance of any such order and the reasons therefor shall be given to the opposing party or parties together with notice of the date, time and place that a hearing on the continuation of such order will be held.
