C.R.S. § 4-2.5-506
Colorado legislative change: In the first sentence of subsection (1) of this section, after the words "must be commenced within", Colorado deleted the words "4 years after the cause of action accrued." and substituted the words "the time period prescribed in section 13-80-101 , C.R.S.". Colorado deleted the second sentence (which read: "By the original lease contract the parties may reduce the period of limitation to not less than one year.") and substituted the following sentence: "This period of limitation may not be varied by agreement of the parties.". These changes parallel the changes that Colorado had previously made to section 4-2-725(1) .
