Colorado: Complete Surplus Funds Recovery Guide -- Tax & Mortgage Foreclosure
Overview
Colorado is one of the most active states in the country for surplus fund recovery, driven by a robust real estate market with significant home price appreciation, a well-defined tax lien certificate system, and a high volume of public trustee foreclosure sales. Colorado is unique in that it uses Public Trustees -- county-level officials -- to conduct non-judicial foreclosures rather than private trustees, which creates a more centralized and accessible system for identifying and claiming surplus funds.
Colorado is among AuctionBlock's 16 qualified operating states. The Denver metro area, Colorado Springs, and the Front Range corridor represent the highest-volume markets. This whitepaper provides a comprehensive guide to surplus recovery from both tax and mortgage foreclosure sales in Colorado.
All statute references are current as of April 2026. Post-Tyler v. Hennepin reforms continue to evolve. Always verify current law before acting.

Tax Lien Certificate System
Colorado is a tax lien state. Under C.R.S. Section 39-11-108, when property taxes become delinquent, the County Treasurer sells tax lien certificates at an annual tax lien sale. Investors bid on the interest rate they are willing to accept (down from the statutory maximum), and the winning bidder purchases the certificate. The property owner retains ownership and has a right of redemption.
Redemption Period
The redemption period in Colorado is three years from the date of the tax lien sale (C.R.S. Section 39-12-104). During this period, the property owner can redeem by paying the certificate amount plus accrued interest and any subsequent tax amounts paid by the certificate holder. If the property is not redeemed within three years, the certificate holder may apply for a Treasurer's Deed (C.R.S. Section 39-11-120).
Treasurer's Deed Process and Surplus
When a tax lien certificate holder applies for a Treasurer's Deed, the County Treasurer issues the deed, effectively transferring ownership to the certificate holder. Under C.R.S. Section 39-11-108(4), if the property was sold (or will be sold) for more than the total of all taxes, interest, penalties, and costs, the surplus belongs to the former owner.
Colorado law was significantly reformed post-Tyler. Under C.R.S. Section 39-12-103.5 (enacted 2024), counties are now required to sell tax-foreclosed properties at public auction rather than simply deeding them to the lien holder for the certificate amount. This reform was a direct response to Tyler v. Hennepin and ensures that surplus value is captured and made available to former owners.
Who Holds the Funds
The County Treasurer holds surplus funds from tax lien foreclosure sales. Each of Colorado's 64 counties maintains its own surplus fund account.
Claim Process and Deadlines
Former owners must file a written claim with the County Treasurer. Under C.R.S. Section 39-12-103.5, the county must provide notice to the former owner at their last known address informing them of any surplus. Claimants must provide:
- Proof of identity
- Proof of ownership at the time of the tax lien sale
- Written claim for the surplus amount
The claim deadline varies by county, but unclaimed surplus funds are subject to Colorado's Unclaimed Property Act (C.R.S. Title 38, Article 13) after the county's holding period. Funds transferred to the State Treasurer's Unclaimed Property Division can still be claimed but require filing through the state rather than the county.
Fee Caps
Colorado enacted C.R.S. Section 38-38-401.5 (effective 2024), which imposes a cap on surplus recovery fees of the lesser of 10% of the surplus or $1,000 for contracts entered into within 45 days of the foreclosure sale, increasing to the lesser of 25% or $5,000 for contracts entered after 45 days. AuctionBlock's $4,999 flat fee must be evaluated against these caps on a case-by-case basis. For claims initiated more than 45 days post-sale where the surplus exceeds $8,000, the $2,000 fee is compliant.
Mortgage Foreclosure Surplus
Public Trustee Foreclosure (Non-Judicial)
Colorado's mortgage foreclosure system is distinctive. Nearly all non-judicial foreclosures are conducted by the Public Trustee in each county, a government official appointed under C.R.S. Section 38-37-101 et seq. The Public Trustee system provides a level of transparency and accountability that is unusual in non-judicial foreclosure states.
The foreclosure process is governed by C.R.S. Section 38-38-101 et seq. (the Colorado Foreclosure Act). After the borrower defaults, the lender files a Notice of Election and Demand (NED) with the Public Trustee. The Public Trustee then conducts a public sale after statutory notice periods have been met.
Surplus Distribution
Under C.R.S. Section 38-38-111, after a Public Trustee sale, proceeds are distributed in the following order:
- Costs and fees of the Public Trustee sale
- The debt secured by the foreclosed deed of trust
- Junior liens and encumbrances in order of priority
- The former owner (grantor)
Surplus funds are held by the Public Trustee and must be paid to the entitled party upon proper claim.
Judicial Foreclosure
Judicial foreclosure is available in Colorado but is less common for residential properties. When used, the court manages distribution of sale proceeds, including surplus. The same priority framework applies.
Lien Priority
Colorado follows a race-notice recording system (C.R.S. Section 38-35-109). Lien priority is generally determined by the date and time of recording. Key considerations include:
- Property tax liens take priority over all other liens by operation of law
- First deeds of trust recorded before subsequent encumbrances have senior priority
- Mechanic's liens may relate back to the date of commencement of work
- HOA liens have limited super-lien priority (discussed below under Edge Cases)
Deficiency Judgments
Colorado permits deficiency judgments after both judicial and non-judicial foreclosure sales, but they are subject to a fair market value limitation (C.R.S. Section 38-38-106). The deficiency is limited to the difference between the outstanding debt and the property's fair market value at the time of sale, not the actual sale price. This means a low auction price does not automatically create a larger deficiency. However, if a deficiency judgment is obtained, it does not reduce the former owner's entitlement to surplus -- surplus exists only when the sale price exceeds the debt.
Claim Process
To claim mortgage foreclosure surplus in Colorado:
- Contact the Public Trustee in the county where the property was located
- Identify the foreclosure file by borrower name, property address, or recording number
- Submit a written claim with proof of identity, proof of ownership, and any supporting documentation
- If competing claims exist or if the Public Trustee cannot determine entitlement, the surplus may be deposited with the court for judicial determination
The Public Trustee is required to distribute surplus to entitled parties. If the former owner does not claim within a reasonable period, the Public Trustee may deposit surplus with the court or report it as unclaimed property.
Attorney Needs
Straightforward surplus claims with a single claimant and no lien disputes can typically be handled without an attorney. Attorney involvement is advisable when: (a) the surplus amount is large (over $25,000), (b) competing claimants exist, (c) lien priority is disputed, (d) the funds have been deposited with the court, or (e) the former owner is deceased and probate issues exist.
Tyler v. Hennepin Impact
Colorado was among the most responsive states to the Tyler v. Hennepin decision. Prior to Tyler, Colorado's tax lien system allowed certificate holders to obtain Treasurer's Deeds without any requirement that the property be sold at fair market value, effectively allowing the certificate holder to capture all equity above the lien amount. Post-Tyler, the Colorado Legislature enacted reforms requiring public auction of tax-foreclosed properties and distribution of surplus to former owners.
The enactment of C.R.S. Section 39-12-103.5 and the fee cap statute C.R.S. Section 38-38-401.5 were both direct responses to Tyler. These reforms have both expanded the pool of recoverable surplus (by requiring auctions that capture market value) and regulated the recovery industry (by capping fees).
For AuctionBlock, the post-Tyler environment in Colorado is favorable: more surplus is being generated, former owners have clearer rights, and the fee cap regime accommodates AuctionBlock's $4,999 flat fee model for most recoveries.
Edge Cases
Deceased Owner: Colorado's probate code (C.R.S. Title 15, Article 12) governs estate claims. A personal representative or heir may claim surplus funds with appropriate probate documentation. Colorado permits small estate affidavits for estates under $70,000 in personal property (C.R.S. Section 15-12-1201), which can simplify the process.
Divorce: A divorce decree allocating property interests governs who may claim surplus. If the property was awarded to one spouse, that spouse has the exclusive right to surplus. If the decree is silent on surplus funds specifically, both former spouses may need to participate.
Bankruptcy: The automatic stay (11 U.S.C. Section 362) may prevent collection of surplus funds if the former owner is in active bankruptcy. The surplus may be property of the bankruptcy estate and subject to the trustee's administration. Post-discharge, the former owner generally retains the right to surplus.
HOA Super Liens: Colorado's Common Interest Ownership Act (C.R.S. Section 38-33.3-316) grants HOAs a super-lien for up to six months of unpaid assessments that takes priority over a first deed of trust. This super-lien can affect surplus calculations when an HOA forecloses or when surplus is distributed after a senior lender's foreclosure.
IRS Liens: Federal tax liens require proper notice to the IRS (26 U.S.C. Section 7425). The IRS has a 120-day redemption right after non-judicial sales. Surplus must satisfy IRS liens before distribution to the former owner.
Multiple Lienholders: Colorado's recording system determines priority. A full title search is essential before advising any claimant. The Public Trustee's records are a good starting point but should be supplemented with a title company search for complex cases.
