Colorado's 182-Day Government Claim Notice, Explained

Not 180 days. Not six months exactly. Colorado's actual number is 182 days — a detail worth getting precisely right, because the Governmental Immunity Act doesn't round in your favor.

A much shorter, separate deadline

Suing a Colorado government entity — the state, a county, a city or town, a school district, or another public body — works differently from suing a private driver or business. Under the Colorado Governmental Immunity Act, C.R.S. § 24-10-109, formal written notice of the claim generally must be given to the public entity within 182 days of the date of the incident — considerably shorter than either the two-year or three-year deadline that applies to a private defendant.

Why the precise number matters

182 days is a genuinely specific figure worth getting exactly right, because it's easy to round it to "six months" in your head and get the actual deadline wrong by a day or two. This detail matters more than it might seem: a notice submitted even a single day late can be treated as untimely under the Act, and Colorado courts generally enforce this deadline strictly.

Notice is a separate step from the lawsuit itself

This 182-day requirement is a mandatory notice step, distinct from the underlying statute of limitations for the type of injury involved. Missing this notice can bar a claim against the government entity before the broader two-year or three-year period most people have heard of would ever come into play — the notice failure ends the claim on its own, independent of how much time remains under the general rule.

Which entities this covers

The Colorado Governmental Immunity Act generally applies to claims against the state, counties, cities and towns, school districts, and other public entities, along with their employees acting within the scope of their duties. Whether a specific defendant — a public hospital, a transit authority, a particular type of special district — falls within the Act's coverage is worth confirming directly, since the answer isn't always obvious from the entity's name alone.

Why this genuinely matters

Because 182 days is dramatically shorter than either general personal injury deadline, and because the consequence of missing it can be just as permanent as missing the underlying statute of limitations itself, identifying early on whether a government entity is involved in any way is one of the single most important steps in a Colorado injury claim.

Colorado government claim notice — frequently asked questions

How long do I have to notify a Colorado government entity of an injury claim?

182 days from the date of the incident, under the Colorado Governmental Immunity Act, C.R.S. § 24-10-109.

Why is Colorado's government notice period 182 days instead of a rounder number?

182 days is simply the figure the Colorado legislature wrote into the Governmental Immunity Act, and it's worth noting precisely because it's easy to mistake for the more commonly seen 180-day period used elsewhere.

Does the 182-day notice replace the underlying lawsuit deadline in Colorado?

No. The notice is a separate, mandatory first step. Missing it can bar the claim before the underlying two- or three-year statute of limitations even becomes relevant.

What entities does Colorado's Governmental Immunity Act cover?

The Act generally covers the state, counties, cities, towns, school districts, and other public entities and their employees acting within the scope of their duties.

What happens if I miss Colorado's 182-day government notice deadline?

The claim against the government entity can be barred entirely, even though the general personal injury statute of limitations hasn't come close to running out.
