When a person claims to be entitled to a vested estate in remainder in lands in this state or to a remainder interest in personalty and his title thereto, or any part thereof, is denied or disputed, or another person claims or is claimed to own the same, or any part thereof or interest therein, or to hold a lien or encumbrance thereon, and no action to which he is a party is pending to enforce or test the validity of any alleged title, interest, claim, lien, or encumbrance, the person claiming to be entitled to the estate or in interest may maintain an action in the superior court to settle the title to the estate or interest and to clear up all doubts and disputes concerning the same.
