C.R.S. § 39-11-133

Suit to quiet title or to try title may be maintained by the grantee or his successors for all or any one or more of the parcels or tracts acquired under tax deed issued pursuant to said notices and requests, and it shall not be a defense or ground of objection to such action that there is a misjoinder of parties or causes of action; but if a defense to such action or a counterclaim is interposed by a claimant to one or more of said parcels, less than all, then the action shall be tried as between the plaintiff and such claimant, separately from the suit as to other parties and other parcels.
