C.R.S. § 38-14-103

(1) Subject to the contrary terms of any written agreement, no action may be brought for damages or the recovery of any loaned property when: (a) Seven years have passed without written contact between the museum and the lender and the lender’s identity or current address is unknown to the museum; or (b) More than one hundred twenty days have passed since a museum has given written notice of termination of a loan pursuant to section 38-14-104 and the lender has not reclaimed the loaned property; except that no lender shall be prejudiced in this regard for want of reasonable cooperation from the museum holding his loaned property.
