You supplied labor or materials on a Colorado county, city, or school project. The public owner may be protected from a mechanic’s lien on the building itself. Payment often runs through a payment bond — Colorado’s Little Miller Act.
This page covers the bond triggers in C.R.S. § 38-26-105 and § 38-26-106, the six-month suit window, and how Darkwell funding can help. For the federal Miller Act and multi-state bond overview, see also Miller Act payment bond claim funding.
Quick note: Darkwell funds legal claims. We’re not a law firm and this isn’t legal advice. Talk with a licensed attorney in your state about your claim and your deadlines. Colorado public-project rules control these claims.

When Colorado requires a payment bond
C.R.S. § 38-26-105 generally requires a penal bond on contracts for more than $50,000 with a county, municipality, or school district for public buildings or public works. Subcontractors, materialmen, suppliers of rental equipment, and others may have a right of action against the principal and surety. The action for labor or materials must be brought within six months after completion of the work.
C.R.S. § 38-26-106 requires a bond (or other acceptable surety) before work starts on covered public contracts, with a penal sum of at least one-half of the contract amount (with a special rule for very large contracts). It applies to local contracts over $50,000 and state contracts over $150,000, among other listed situations.
- Get the bond. Ask for the bond number, surety, and penal sum early.
- Watch the six-month clock under § 38-26-105(1).
- Public prompt-pay rules may also apply under C.R.S. § 24-91-103.

Bond claim vs. waiting on the GC
On public jobs, waiting for the prime to get paid can burn the bond deadline. Talk with a Colorado attorney as soon as payment stalls.
Funding a bond claim
Bond claims still need counsel, notices, and often litigation against the surety. Darkwell funding can help carry those costs on qualifying claims.
