How surplus escheats here
When a tax-foreclosure or mortgage-foreclosure sale generates a surplus that the former owner never claims, the funds follow the path described in escheat-and-unclaimed-property: after the disbursing office’s own claim window runs, the residue is reported and delivered to the State Treasurer as a dormant intangible, held custodially (custody, not title). For Colorado-specific surplus mechanics — Colorado tax-lien sales run through the county treasurer, and overbid/surplus handling is set by statute — see colorado Module 3.
Colorado has adopted the Revised Uniform Unclaimed Property Act (RUUPA, 2016) — it is
listed among early RUUPA enacting states in escheat-and-unclaimed-property — codified at
C.R.S. tit. 38, art. 13 (Colorado RUUPA). The general dormancy period is typically
three years under RUUPA, but the precise Colorado period and the surplus/overbid cite are
needs_verification against the primary statute. (Source: Colorado Treasury, retrieved

Claiming
Search by name at https://unclaimedproperty.colorado.gov/ , then file a claim online or by mailed form (Great Colorado Payback). The owner, estate, or lawful heir may claim. Proof typically required: government-issued photo ID, Social Security number, and documentation linking the claimant to the reported address/property; estates and heirs submit additional probate or heirship documentation. There is no fee to file directly with the State.
