How to File a Small Claims Case Against a Business in Connecticut

If you need to sue a business in Connecticut small claims court, the process is the same as suing an individual — with one critical extra step that determines whether your case survives or gets thrown out before it starts: you must identify and name the correct legal entity. Filing against "Joe's Auto Repair" when the legal entity is "Joseph Martinez LLC d/b/a Joe's Auto Repair" can leave you with a judgment that is difficult to enforce. Getting the name right is more important than getting the forms right.

Here's how the entire process works when the defendant is a business, from entity verification through the hearing.

Step 1: Identify the Legal Entity

The name on a storefront, website, or invoice is often a trade name ("doing business as"), not the legal entity. Connecticut requires you to sue the entity that can actually be held liable — the registered LLC, corporation, partnership, or the individual owner behind the trade name.

Where to search:

• Secretary of the State CONCORD database (business.ct.gov) — Search for corporations, LLCs, limited partnerships, and statutory trusts registered in Connecticut. The record shows the legal entity name, registered agent, and service-of-process address.
• Town clerk trade name filings — Sole proprietors and partnerships register trade names with the town clerk in the municipality where they operate. If the business isn't in CONCORD, the town clerk's records may show the individual owner behind the trade name.

How to name the defendant on Form JD-CV-40:

Getting this wrong is the most common reason business-related small claims cases fail in Connecticut. A judgment against a trade name that isn't tied to the legal entity is unenforceable — you've won on paper against a name that doesn't legally exist.

Step 2: Verify the Dollar Limit

The standard Connecticut small claims limit is $5,000. Two exceptions matter when suing a business:

• Home improvement contractors: For qualifying claims involving a registered home improvement contractor or new home construction builder, the limit rises to $15,000 under C.G.S. § 51-15(d). Verify home-improvement contractor registration through the Connecticut Department of Consumer Protection.
• Security deposit claims: A qualifying tenant security-deposit claim under C.G.S. § 47a-21 may exceed $5,000 because the statute permits double damages and costs beyond the general limit.

For claims above the applicable limit, you can waive the excess and stay in small claims, or file in regular Superior Court (where attorney fees become a more practical consideration).

Step 3: Send a Demand Letter

Before filing, send a formal demand letter to the business via certified mail with return receipt requested. Address it to the registered agent if the business is an LLC or corporation (the CONCORD record has the address), or to the individual owner at the business address for sole proprietors.

A demand letter isn't legally required for most contract claims, but it accomplishes three things:

1. It creates a paper trail showing you attempted to resolve the dispute before going to court
2. It puts the business on notice of the specific amount and basis of your claim
3. It gives the business a clear chance to resolve the dispute before filing

For claims under the Connecticut Unfair Trade Practices Act (CUTPA, C.G.S. § 42-110g), a written pre-suit demand is required to preserve claims for multiple or punitive damages.

A demand letter does not toll or suspend the statute of limitations, so do not let a response window cause you to miss your filing deadline.

Step 4: Serve the Business (Before Filing)

Connecticut requires you to serve the defendant before filing with the court. This is the step that catches most first-time filers off guard — in most states, the court handles service after you file.

How to serve a business entity:

• Connecticut-organized LLC or corporation with a registered agent: Send the writ (JD-CV-40) with JD-CV-121 (Instructions to Defendant) via certified mail, return receipt requested, to the registered agent's address from the CONCORD record. The registered agent is the person designated to accept legal papers on behalf of the entity. Out-of-state business defendants must instead be served by a proper officer under JD-CV-122.
• Sole proprietor: Serve the individual owner at their home or business address via certified mail, return receipt requested.
• State marshal service: If the business refuses certified mail or the address is uncertain, a Connecticut state marshal can serve the papers in person ($30–$70+, varies by mileage). If your fee waiver (JD-CV-120) is approved, the court orders state-paid marshal service.

When the return receipt ("green card") comes back signed, complete Form JD-CV-123 (Statement of Service) recording the delivery details. Keep the green card — you'll file it with the court.

If certified mail is returned undelivered, update the address or use a state marshal for in-person service.

Step 5: File with the Court

Once you have valid proof of service, file these documents with the Centralized Small Claims Processing Office in Hartford:

1. Form JD-CV-40 — the completed writ
2. Form JD-CV-123 — your Statement of Service
3. Proof of service — the signed return receipt or marshal's return
4. $95 filing fee — check payable to "Clerk of the Superior Court" (or Form JD-CV-120 for a fee waiver)
5. Supporting documents — contracts, invoices, photos, or receipts supporting your claim

You can file by mail to the Hartford processing office or electronically through the Connecticut Judicial Branch E-Services portal.

Step 6: Prepare for the Hearing

Business defendants are more likely than individuals to show up prepared. Expect the business to bring invoices, contracts, communication records, or a representative who disputes your version of events.

Organize your evidence:

• Contracts or written agreements (the original if possible)
• Invoices, receipts, or payment records
• Photos of damaged property or incomplete work (printed, not on your phone)
• Text messages, emails, or letters — printed and in chronological order
• The demand letter and proof of delivery
• Any response from the business

Keep everything in a binder, tabbed by document type. Connecticut small claims hearings are informal, and an organized binder helps you find any document quickly. Having an organized binder signals you've done your homework.

Special Situations

Out-of-state business with Connecticut operations: Foreign corporations and LLCs doing business in Connecticut can be sued in small claims court. An out-of-state business must be served by a proper officer under JD-CV-122. For a foreign corporation authorized to transact business here, use its registered agent under C.G.S. § 33-929; for a registered foreign LLC, use its registered agent under § 34-243r. If the business is not registered, confirm the statutory service route before serving.

Out-of-state individual sole proprietor: Small claims jurisdiction is barred against non-resident individuals unless they own property in Connecticut. You'd need to file in regular court or in the defendant's home state.

Franchise operators: Identify the entity that actually contracted with you or is responsible for the claim, then verify its legal name through CONCORD or the relevant town clerk.

Who This Is For

• Anyone in Connecticut who needs to sue a business — contractor, landlord/property manager, retailer, service provider, or business that owes money
• People whose demand letter to the business was ignored or refused
• Filers comfortable with paperwork when given step-by-step instructions
• Claims under $5,000 (or up to $15,000 for qualifying registered home-improvement contractors or new-home-construction builders)

Who This Is NOT For

• People who need to sue an out-of-state individual with no Connecticut property — small claims court doesn't have jurisdiction
• Claims for non-monetary relief (injunctions, specific performance, evictions) — small claims is strictly monetary
• Cases where you're unsure whether the business entity is the right defendant — consult a lawyer before filing against the wrong name

Frequently Asked Questions

What if I can't find the business in the CONCORD database?

The business may be a sole proprietorship operating under a trade name without an LLC or corporate filing. Check the town clerk's office in the municipality where the business operates for a trade name certificate. If you find the owner's name, sue them individually with "d/b/a [business name]."

Can I sue a business that closed down?

Check the CONCORD record for dissolution status and confirm the proper defendant and service address before filing. For a sole proprietorship, name the individual owner behind the trade name.

What happens if the business sends a lawyer to the hearing?

Businesses may appear through a licensed attorney or an authorized corporate officer. Present your evidence clearly and answer the magistrate's questions; the hearing procedure is informal.

Can I recover my court costs if I win?

Form JD-CV-40 separates costs from the amount claimed and says not to include the filing fee in that amount. List costs separately; the court determines which costs are allowable.

What if the business files a counterclaim above the applicable limit?

If a defendant's counterclaim exceeds the applicable small claims limit ($5,000 generally, or $15,000 for qualifying home-improvement or new-home-construction claims), either party can request a transfer to the regular civil docket. The transfer fee is $125, and the case then proceeds under full civil procedure — where legal representation becomes more practical.
