Worked example

What that means in dollars

On a $1,500 deposit wrongfully withheld in full, Colorado law allows pursuing up to $4,500, plus attorney’s fees where the statute allows. Most landlords understand this math, which is why a letter citing Colo. Rev. Stat. § 38-12-103 is often enough to get a check without going to court.

Where the Colorado letter ends up

Nothing is charged until you have read the letter that will be sent. After you sign it, we handle the printing, the postage and the trip to the Post Office, and you keep the certified tracking, the delivery record and a signed copy you can check against its own fingerprint.

How it works covers every step, and what it costs to do the same thing alone.

The bit that stops them arguing

Not a logo that says “verified.” A short record of how and when you signed, printed on the letter your Colorado landlord is holding, plus a code made from the letter's own words.

  • The demand paragraph
  • The signature record
  • The SHA-256 hash
  • Certified Mail with Return Receipt
Pin 1 · The demand paragraphThe paragraph names your state's statute, the amount your landlord kept, the deadline they missed, and gives them a firm deadline to send the money before the letter says what happens next. Every part of it comes from the answers you gave, printed in the order the law expects.
Pin 2 · The signature recordMethod (drawn or typed), date, time zone, IP, browser, and consent to sign electronically. Printed on the letter itself, so the person receiving it can see how it was signed. Nothing goes out until a real person signs.
Pin 3 · The SHA-256 hashA 64-character code built from every word in your letter, recorded with the date and time you signed. It is your signing record: paste it into the checker at /verify/ and it confirms the wording you hold is the wording you signed, unchanged. It is not proof of delivery; the certified mail record below is.
Pin 4 · Certified Mail with Return ReceiptSomeone at the other end has to sign. This is the proof: the certified mail receipt, the USPS tracking history, and the delivery signature with its date. The Postal Service records them, our mail partner passes them to us, and we email them to you and post them on your letter tracker. Your landlord cannot claim the letter never came.

The closing words above are the real ones our engine writes for Colorado letters, statute and deadline included. The name, signature and codes are made up; yours carry your own record. The time is shown in the signer's own time zone, not ours.

That code is built from every word in your letter. Change one word and it no longer matches. Type it into our checker and it tells you the letter is the same one you signed. See how a Colorado letter checks out →

How the Colorado clock actually runs

Before anything else, be precise about the clock. Almost every argument in a deposit dispute is really an argument about a date.

In Colorado the window is 30 days. In full: one month by default; up to 60 days if the lease says so. Read that phrasing twice: it is doing real work.

  • It is not one flat number. The window changes depending on what happened at the end of your tenancy, so the honest answer to “how long do they have?” depends on facts only you know. Work out which branch you are in before you accuse anyone of being late.
  • Measure from possession, not from the lease end date. Leases end on paper; tenancies end when the keys change hands. Where those are different days, it is usually the second one that matters.
  • A missed deadline does not expire your claim. It is the landlord’s obligation that was late, not your right that lapsed. Renters routinely assume that being weeks past the date means they have lost their chance. The opposite is closer to the truth.

The Colorado detail most renters never find

One Colorado wrinkle is worth knowing before you send anything:

Tenant must give seven days' notice of intent to sue before filing for treble damages.Colo. Rev. Stat. § 38-12-103 · general legal information, not legal advice

It is the sort of detail that never comes up until it is used against you. Better to have accounted for it in the letter than to meet it for the first time in a reply.

What you can actually ask for in Colorado

Most renters ask for their deposit back and stop there. Colorado law generally has more to say about a landlord who gets this wrong.

Willful wrongful withholding can make the landlord liable for treble the amount wrongfully withheld, plus attorney's fees and costs.Colo. Rev. Stat. § 38-12-103 · general legal information, not legal advice

A landlord who has read that sentence is in a different frame of mind from one who has not. The point is not to threaten. It is to make clear that the cheap option they were relying on is not actually the cheap option.

Courts decide actual awards, and statutes carry conditions and exceptions. What the statute names is the most a judge may award on the right facts, never a promise about your letter.

What to do first

An evening’s work, no legal knowledge required. It is most of what separates renters who get paid from renters who give up.

  1. Fix the handover date in your own mind before anyone else does. Lease end dates and possession dates are often different days, and it is almost always the second that counts. Find the message, receipt or move-out inspection note that proves which day it was.
  2. Prove you told them where to send it. “They knew my new address” is not evidence; a dated message containing the address is. If you can't find one, that gap is worth closing now rather than discovering it later.
  3. Treat their deduction list as an asset, not an insult. The weaker it is, the better it is for you. Unsupported line items are exactly what a judge asks a landlord to justify, and they usually can't.
  4. Rescue your moving day photographs from your phone. The original files carry the date inside them, which is what makes them worth anything. Copies of copies lose that, and phones are not archives.
  5. Answer a short payment in writing. Take the money if you need it, but put on record that it does not close the matter. Otherwise the payment itself becomes their best piece of evidence.

What is typically at stake in Colorado

Some background on the amounts, since they shape how both sides behave. Median gross rent in Colorado runs about $1,761 a month, and roughly 34% of households, some 802,483 of them, rent rather than own (ACS 2024 5-year). Where a deposit is set around a month’s rent, a typical Colorado deposit lands near $1,761.

Hold those two facts together and the behavior makes sense. For you it is next month’s rent; for a landlord with a portfolio it is an administrative annoyance worth postponing indefinitely. Nothing changes until the postponing starts costing them something.

Where a Colorado deposit case goes if the letter does not work

Most letters never see a courtroom. That is rather the point of sending one. But the letter borrows its weight from what sits behind it.

In Colorado that is the Small Claims Court (County Court). At $7,500, the court's limit sits well clear of a typical Colorado deposit, so for most renters it is not the constraint. Proving the number is.

This forum is built for people without lawyers: simplified filing, relaxed evidence rules, and judges used to hearing renters directly. You normally file where the property is or where the landlord can be found, pay a filing fee that is a small fraction of the claim, and arrange formal service. Filing fees, service rules and local procedure are set by the court rather than by us. The Colorado judiciary publishes its own small claims instructions and forms, and that is the page to read before you file.

Judges in this forum decide quickly and on documents. The renter who arrives with a dated demand and a signed USPS delivery record is in a materially different position from the one describing a series of phone calls.

Colorado deposit questions

Colorado deposit questions, answered

How long does a landlord have to return a security deposit in Colorado?
Under Colo. Rev. Stat. § 38-12-103, the landlord generally must act within one month after termination (up to 60 days if the lease so provides). If the landlord keeps any portion, an itemized written statement of deductions is required. This is general legal information. The statute contains conditions and exceptions.
What happens if my landlord misses the Colorado deadline?
Willful wrongful withholding can make the landlord liable for treble the amount wrongfully withheld, plus attorney's fees and costs. A written demand letter that cites Colo. Rev. Stat. § 38-12-103 puts the landlord on notice that you know the rules they broke and what the statute allows you to pursue.
How do I write a security deposit demand letter in Colorado?
A security deposit demand letter for Colorado needs five things. Your tenancy facts (address, move out date, deposit amount), the statute citation (Colo. Rev. Stat. § 38-12-103), the deadline the landlord missed, the remedies the statute allows, and a clear payment demand with your forwarding address. Our free annotated Colorado sample letter shows the full structure. Or answer a few questions and we generate yours with your facts and mail it certified.
Do I need a lawyer to send a demand letter in Colorado?
No. A demand letter is something any tenant can send on their own behalf. If it comes to suing, deposit cases in Colorado go to the Small Claims Court (County Court), which is built for people without lawyers and hears claims up to $7,500. Our service prepares the letter from the facts you provide and the current text of Colo. Rev. Stat. § 38-12-103, and mails it by USPS Certified Mail so you have proof of delivery. If your dispute is complex or high-value, talking to a licensed Colorado attorney is a sensible next step. Several statutes shift attorney's fees to the landlord.

If the letter doesn’t work: filing in Colorado

Where a Colorado claim is filed

A Colorado security deposit claim that does not settle is filed in the Small Claims Court (County Court), which hears claims up to $7,500.

Fits under $7,500 while the deposit is below about $2,550. Note the math: above a deposit of roughly $2,550, the statutory ceiling passes the $7,500 limit, so a claim that large belongs in a higher court, or the excess can be waived to stay in small claims. Settling on a certified demand letter avoids that fork entirely.

The claim rests on Colo. Rev. Stat. § 38-12-103. Colorado’s deposit statute can shift attorney’s fees to the landlord, which matters even if you never hire one. Filing fees, forms and service rules are the court’s, not ours: the Colorado judiciary’s own small claims instructions are the authority to check before filing.

How much can I sue my landlord for in Colorado small claims court?
The Small Claims Court (County Court) hears claims up to $7,500. Your claim is the withheld deposit plus whatever Colo. Rev. Stat. § 38-12-103 allows on top: up to 3× the wrongfully withheld amount. Fits under $7,500 while the deposit is below about $2,550.

General legal information, not legal advice. Court limits and procedures change; confirm with the clerk or a licensed Colorado attorney before filing.
