C.R.S. § 11-105-503

A lessor may lease a safe deposit box to, or accept property for safekeeping from, a minor and, in connection therewith, deal with such minor to the same effect as if dealing with a person of full legal capacity, unless and until the minor’s guardian or conservator files with the lessor a certified copy of the order of a Colorado court having jurisdiction appointing such guardian or conservator and directs otherwise.
