not in being - Direction for sale and holding proceeds in trust.

If it shall appear in any suit or proceeding in a district court

involving real estate that any person or persons not in being are or

may become entitled to, or may upon coming into being claim to be

entitled to, any future interest in such real estate, legal or

equitable, and if it further appears to be expedient or for the best

interests of all concerned, the court may by order determine the

rights of all living persons in such real estate and the

circumstances under which persons not then in being may claim an

interest therein in the future and determine the nature and extent

of any such interest or claim and may direct the sale of the full

claimed, and direct that the proceeds of the sale shall be held as a
