What to do when a customer claims your work is defective and won't pay.

You finished the job in the spring. The customer walked the space, signed off on the punch list, and moved in their equipment. Now the final payment is due, and out of nowhere the work is 'defective.' The complaints are vague, the invoice is unpaid, and you are left wondering how a project everyone seemed happy with turned into a fight over money. When a customer claims your work is defective to avoid paying, the accusation can feel personal. It is also a business problem with a fairly predictable set of answers.

The good news for contractors and trade businesses across central Indiana is that a bare accusation is not proof. A customer who withholds payment and points to supposed defects generally has to back that up with more than frustration. Your job is to be ready to show you did the work the contract called for, and to make it easy for a court, a mediator, or the customer's own lawyer to see it. That readiness starts long before anyone files anything.

Who has to prove the work was defective?

In Indiana, the party claiming the work is defective generally carries the burden of proving it. If you sue for the unpaid balance, you show the contract, that you performed, and the amount still owed. The customer then has to support the defect claim with evidence rather than a bare accusation.

That distinction matters because 'defective' is a conclusion that needs support. To make it stick, a customer usually needs to show that the work fell short of what the contract required or below the accepted standard in your trade, and that the shortfall caused an actual, measurable problem. A complaint that something 'looks wrong' or 'isn't what I pictured' is not the same as a code violation or a failed inspection. Where a genuine defect exists, Indiana law generally measures the customer's damages by what it costs to correct the work or by any drop in the property's value, instead of the full contract price. A minor issue does not excuse a customer from paying for the value they received.

What the contract and the plans actually say.

Many defective work disputes are decided by the contract, the plans, and the specifications, so that is where any honest review begins. The scope of work defines what you agreed to deliver. Approved drawings, submittals, and specifications define how. If the contract set a standard, that standard controls; if it was silent, courts look to ordinary practice in your trade for similar work in the same area.

Consider a Westfield electrical contractor who wires a new retail buildout to the approved plans and passes every inspection. Six weeks after the store opens, the owner complains that some lights flicker and declares the electrical work defective, holding back the final payment. Whether that flickering is your problem depends on facts the contract helps sort out. If the owner later added fixtures on their own, overloaded a circuit, or bought dimmers that do not match the LED drivers, the flicker may have nothing to do with your installation. The approved plans, your permit sign-offs, and the load calculations tell that story better than any argument you could make from memory.

Acceptance and warranty terms matter too. If the customer inspected and accepted the work, used it for months, and did not raise a concern until the invoice came due, that timeline is worth documenting. A warranty clause may also define what you are responsible for and for how long, which can narrow a sprawling complaint down to something specific and manageable.

The documents and photos that win these disputes.

These cases are won on records rather than recollection. The contractor who can produce a signed contract, approved plans, dated photographs, and a paper trail of approvals is in a much stronger position than one relying on what everyone remembers about a job that wrapped up months ago. Memories fade, crews move on, and the customer's version tends to sharpen in their favor over time.

The records worth having in a construction dispute usually include:

•        The signed contract and every signed change order, so the agreed scope and price are not in question.

•        Dated photos and video at each phase, especially of work that later gets covered up, like wiring in walls or prep under a slab.

•        Permits, inspection approvals, and any third-party sign-offs.

•        Emails and texts with the customer showing approvals, direction, and their satisfaction along the way.

•        Invoices, payment records, and the punch list with its sign-off.

Photographs of concealed work deserve special attention. Once drywall goes up or concrete is poured, you cannot re-create what was underneath, and a clear set of dated images can end an argument before it starts. Keeping this kind of record is a habit worth building on every job rather than a scramble after a dispute begins.

Give them a chance to inspect and repair.

Offering to inspect and fix a genuine problem is good business and strong evidence at the same time. When a customer raises a defect, a written offer to come look at it, and to correct anything that is actually your responsibility, does two things. It may resolve the matter for the cost of an afternoon, and it shows anyone who later reviews the file that you acted reasonably. If your contract includes a right-to-cure provision, follow it as written, because skipping that step can undercut an otherwise solid position.

The offer also tends to reveal what is really going on. A customer with a legitimate concern usually welcomes a fix. A customer who is stalling on payment, or who caused the problem themselves, often refuses to let you inspect or keeps moving the goalposts. Either way, put the offer in writing and keep the response. When the dispute is mostly about getting paid, a well-timed demand letter, sometimes one sent by an attorney, can move a stalling customer, and it is worth understanding whether a demand letter actually works before you send one. If you do end up in court and your contract or the situation allows it, you may also be able to recover your attorney fees, though that depends on the facts.

When to bring in a lawyer.

You do not need counsel for every unhappy customer, but some situations call for one sooner rather than later. Consider talking to a lawyer when the withheld amount is large enough to hurt your cash flow, when the customer hires their own attorney or sends a formal demand, when the claim involves alleged code violations or safety issues, or when the customer refuses to let you inspect while continuing to withhold payment. A threat to sue, a claim against a payment bond, or a complaint to a licensing body are all reasons to get advice before you respond on your own. For smaller balances, Indiana's small claims courts offer a faster, less formal option, and the Indiana Judicial Branch publishes guidance on how they work.

The earlier you involve someone, the more options you tend to have, because evidence is fresh and deadlines have not passed. An attorney who works with construction and the trades can help you decide whether to record a lien, send a demand, file suit, or simply document the file and wait.

Frequently asked questions about defective work claims.

What should I do first if a customer says my work is defective?

Ask for the complaint in writing and get specific about what they believe is wrong. Offer, in writing, to inspect the work and correct anything that is actually your responsibility. Pull your contract, plans, photos, and approvals together while the details are fresh. Avoid admitting fault before you understand the claim.

Can a customer refuse to pay just because they are unhappy with the work?

General dissatisfaction is not the same as a defect. A customer who withholds payment usually has to show the work fell below the contract or the accepted standard in your trade and caused an actual problem. If the work substantially met the contract, they generally owe you for the value delivered, minus the cost of any legitimate correction.

How do I prove my construction work was not defective in Indiana?

You prove it by comparing the finished work to what the contract required and backing that up with documents. A signed contract, approved plans, dated photos, permits, inspection approvals, and communications showing the customer's approvals all help. Where the work is technical, an independent inspection by a qualified person in the trade can confirm it met the standard.

Who pays for an inspection or evaluation of the work?

That depends on the contract and the situation. Sometimes each side hires its own evaluator, and sometimes the parties agree to share one. If the matter ends up in court, the losing side may end up responsible for certain costs, but that is not guaranteed and varies by case.

What if the customer already accepted and used the work?

Acceptance and continued use can weaken a later defect claim, though they may not eliminate it, especially for hidden problems. The timing matters here. A customer who used the space for months without complaint and raised issues only when the invoice came due will have a harder time than one who flagged a problem right away.

Should I offer to fix the problem even if I think the work is fine?

Offering to inspect and correct a genuine issue is usually smart, even when you are confident, because it is inexpensive and it protects you later. You are not admitting fault by offering to look. Put the offer in writing, and if the customer refuses, that refusal becomes part of your record.

How long do I have to sue a customer for non-payment in Indiana?

Indiana sets deadlines for filing a lawsuit on a contract, and they are longer than the deadlines for a mechanic's lien, but they are not open-ended. The specific period depends on the type of contract and other facts. Because missing a deadline can end your claim, confirm the current deadline for your situation before you assume you have time.

Can I recover my attorney fees if I have to sue to get paid?

Sometimes. Indiana generally follows the rule that each side pays its own fees unless a contract or a specific law says otherwise. If your contract has a fee-shifting clause, or a particular statute applies, you may be able to recover fees. It is worth checking your contract before you decide how to proceed.

What is the difference between defective work and incomplete work?

Defective work was done but does not meet the required standard. Incomplete work was not finished at all. The distinction affects what the customer can withhold and how damages are measured, so it is worth being clear about which one the customer is actually claiming.

If a customer is holding back payment and calling your work defective, you do not have to sort it out alone.
