C.R.S. § 15-11-1215: Filing or registering of disclaimer.

If an instrument transferring an interest in or power over property subject to a disclaimer is required or permitted by law to be filed or registered, the disclaimer may be filed or registered. Failure to file or register the disclaimer does not affect its validity as between the disclaimant and persons to whom the property interest or power passes by reason of the disclaimer, provided, however, that a disclaimer of an interest in real property in which the disclaimant has a recorded interest is not effective and therefore is not valid as between any persons until a copy of the disclaimer is recorded in section 15-11-1212 (15).
