Connecticut Small Claims Demand Letter: When You Need One and How to Write It

Is a Demand Letter Required?

For most Connecticut small claims cases — unpaid invoices, property damage, breach of contract — a demand letter is recommended but not legally required. You can file without one.

Two points to distinguish from a demand letter:

Security deposit claims. Under CGS § 47a-21(d)(2), the landlord must deliver the deposit balance and any itemized deductions within 21 days after the tenancy ends or 15 days after receiving written notice of the tenant's forwarding address, whichever is later. A written forwarding address is important to establish the later deadline.

CUTPA claims. CGS § 42-110g does not require a private plaintiff to send a written pre-suit demand letter to bring a CUTPA claim or request punitive damages. A letter can still give the other party a chance to resolve the dispute.

Why Send One Anyway

Even when it's optional, a demand letter does real work:

It often resolves the dispute. Community discussions from Connecticut filers consistently mention that simply serving the JD-CV-40 writ — or even just sending a formal demand letter — prompted payment before the case went further. People take a certified letter more seriously than a text message.

It creates a paper trail. If the case goes to hearing, showing the magistrate that you made a reasonable attempt to resolve things before filing strengthens your position.

It documents the amount owed. The letter establishes exactly what you're claiming and why, which prevents the defendant from arguing later that they didn't understand what was expected.

What to Include

Keep it factual and short. A demand letter is not a legal brief.

Date and your contact information. Full name and mailing address.

The defendant's full legal name and address. For businesses, use the legal entity name — the same one you'd put on the writ.

What happened. Two or three sentences covering the transaction, the breach, and the amount owed. "On March 15, 2026, I paid you $3,200 for kitchen cabinet installation under our written contract. No work was performed. You owe $3,200."

The deadline to pay. Give a reasonable timeframe — 14 to 30 days is standard. "Please remit $3,200 within 21 days of this letter."

What happens next. "If payment is not received by [date], I intend to file a small claims action in Connecticut Superior Court to recover this amount plus filing costs."

Send It by Certified Mail

Always send by certified mail with return receipt requested. The green card proves the letter was delivered. Regular mail works too, but you can't prove receipt.

Keep a copy of the letter, the certified mail receipt, and the return receipt (green card) together. If you end up filing, these go into your evidence binder.

A Demand Letter Does Not Stop the Clock

One important point: sending a demand letter does not toll or suspend the statute of limitations. If your deadline to file is approaching — 6 years for written contracts, generally 3 years for oral contracts (6 if one side fully performed), and 2 years from discovery for property damage (subject to a 3-year limit from the act) — the clock keeps running while you wait for a response.

Don't let a generous payment deadline push you past the filing deadline.
