All proceedings for termination of life estate conducted prior to July 1, 1957, in which personal property has been involved, in which two or more life tenants were named, or in which the remaindermen were not identical as to all property involved, are hereby legalized, cured, and validated, and all such proceedings are hereby declared to be in all respects of like force and effect as if expressly authorized by the law in effect at the time such proceeding was conducted.
If any person had any vested right in any property, or other rights of any kind, by reason of any of the matters referred to in paragraph one hereof, if no action or proceeding to enforce such right was begun prior to July 1, 1958, such rights shall be forever barred; and no action or proceeding so brought is of any force or effect, or maintainable in any court of this state, unless, prior to July 1, 1958, there was recorded in the office of the register of deeds of the county in which the property affected is situated, a notice of the pendency of such action, in accordance with the provisions of chapter 15-10.
