C.r.c.p. 71
When an order is made in favor of a person who is not a party to the action, he may enforce obedience to the order by the same process as if he were a party; and, when obedience to an order may be lawfully enforced against a person who is not a party, he is liable to the same process for enforcing obedience to the order as if he were a party.

Annotation Person who has advanced money on realty may be awarded lien. In an action to quiet title where the plaintiff names as defendants all "persons who claim any interest in the subject matter of this action", a person who has advanced money in connection with the realty has a sufficient interest to be a party and to be awarded a lien to secure such advance. Hahn v. Pitts, 118 Colo. 173, 193 P.2d 716 (1948).
