Paid in Full Checks in New Jersey: Before You Deposit a Disputed Payment

How to handle a check offered as settlement of a disputed invoice
By Peter J. Lamont, Esq.

A customer disputes your $18,000 invoice and sends a $10,000 check with a letter calling it final payment. You need the money for payroll and intend to collect the remaining $8,000 later. Depositing the check could prevent you from doing that. Paid in full checks in New Jersey can settle a disputed claim even without a separately signed settlement agreement. Whether that happens depends on the dispute, the payment language, and how the check was handled.
For a business that uses a bookkeeper, a check may be deposited before the owner learns that it arrived. Unless someone flags the account, it can be processed with the day’s other receipts. This is a particular concern when the customer discusses the dispute with one employee but sends payments to another. Whoever handles deposits needs access to that correspondence.
When Paid in Full Checks in New Jersey Can Settle a Claim
The starting point is N.J.S.A. 12A:3-311, which addresses accord and satisfaction by use of an instrument. In practical terms, an accord is an agreement to resolve a claim, and satisfaction is the performance that carries out that resolution. A check can be the means of accomplishing both.
The statute requires more than someone writing a few words on a payment. The person asserting the defense must establish a good-faith tender as full satisfaction, a claim whose amount was unliquidated or genuinely disputed, and the claimant’s obtaining payment. Subject to statutory exceptions, a conspicuous statement on the instrument or an accompanying written communication that the payment fully satisfies the claim can result in discharge.
The cover letter needs to be read along with the check. Settlement language can appear in either place. Keep the envelope, remittance advice, and correspondence with the payment so that the person reviewing it can see everything the customer sent.
The customer in this hypothetical might claim that some of the billed services were never authorized or performed. If that dispute is genuine and the remaining statutory requirements are met, collecting the $10,000 could discharge the claim for the balance. The words on the memo line do not answer all of those questions.
A Genuine Dispute Is Different From an Unpaid Invoice
An overdue bill is not necessarily a disputed bill. A customer may admit owing the full amount but ask you to accept less because money is tight. That differs from a disagreement over what the contract required or whether the work was completed. Section 3-311 requires an unliquidated amount or a bona fide dispute.
Before depositing the check, review the account. Compare the customer’s objections with the signed agreement and the records of the work performed. Were changes approved? Did the customer raise a complaint before the invoice became overdue? Save the relevant messages and check whether anyone has already agreed to settlement terms.
Our New Jersey contract attorneys can review the agreement and payment correspondence to assess whether the records support the customer’s claimed dispute and how the payment should be handled.
Good faith is also a statutory requirement. A manufactured dispute or concealed settlement condition may raise a serious problem with that requirement. Have counsel assess it before you deposit the check, however. If the customer later argues that the debt was settled, you may have to litigate the issue to recover the balance.
Why Writing Under Protest May Not Protect the Balance
Adding “under protest” or “partial payment only” after crossing out “payment in full” is not a reliable way to preserve your claim. The added words may show that you objected, but they do not necessarily prevent the check from settling the dispute.
N.J.S.A. 12A:1-308 generally addresses performance or acceptance with an explicit reservation of rights. But subsection (b) expressly excludes accord and satisfaction from that protection. The reservation-of-rights rule therefore should not be treated as an escape from the conditional-payment statute.
For a check offered in settlement, get advice before depositing it. If you reject the proposed settlement, counsel can address returning the payment and requesting an unconditional replacement. Keep a copy of the original check and all accompanying correspondence. Altering the check yourself does not resolve the legal issue.
A written agreement should confirm that both parties intend to treat the money as a partial payment before the check is deposited. Identify the amount still in dispute and confirm that accepting the payment will not settle it. Both parties need to agree; a note added by the creditor alone is different.
Paid in Full Checks in New Jersey Have Limited Statutory Exceptions
Section 3-311 provides two exceptions, each with specific requirements. The first applies to an organization that previously sent a conspicuous statement directing disputed-debt communications, including payments offered in full satisfaction, to a designated person, office, or place. Counsel must check whether the statement qualifies and whether the payment reached the designated recipient.
The second concerns tendering repayment within 90 days after payment of the instrument. It does not apply to an organization that sent the qualifying designated-recipient statement. The deadline is measured from payment of the instrument, so obtain the bank records promptly if a check has already been collected.
Both protections are subject to subsection (d), which addresses actual knowledge by the claimant or an agent with direct responsibility for the disputed obligation before collection was initiated. The interaction among these provisions requires a factual review of who knew what, when they knew it, and how the check was processed.
If the check has already been collected, gather the deposit records, check images, and correspondence for counsel right away. Include internal messages showing who reviewed the payment and when. Get advice before sending a refund or demanding the balance; the available response depends on those facts and the statutory deadlines.
Create a Payment Review Process Before the Next Dispute
A clear instruction should require employees to hold any payment marked “final settlement,” “full satisfaction,” or similar language for review. The same instruction should apply when those words appear in a letter accompanying the payment. Staff should know whom to contact and where to keep the check while a decision is made.
Assign that review to someone who knows the account and can obtain legal advice. Include outside bookkeepers in the procedure, especially if they use remote deposit. When an owner receives a customer’s complaint, the person handling that customer’s payments needs to know about it.
Keep the dispute correspondence and payment records together, with a note of who approved or rejected each conditional payment. If you want to use the statute’s designated-recipient procedure, have counsel prepare the notice and advise how to send it. An internal instruction alone does not satisfy the requirement to notify the customer.
For businesses in Wyckoff and throughout Bergen County, our business law practice can review payment procedures and the contract terms behind disputed accounts. Those procedures should fit how the business actually receives and deposits checks.
Record the Settlement Terms
Settling for $10,000 on an $18,000 invoice may be a reasonable decision if collection will be costly or the customer has a substantial defense. Before agreeing, decide exactly which claims the payment will settle. That becomes especially important when you have other unpaid invoices for the same customer.
When preparing the settlement, identify the parties and invoices it covers, when payment is due, and the scope of any release. State which obligations remain. If several projects are involved, referring only to “the account” leaves room for another disagreement about what was settled.
If the dispute proceeds to business litigation, counsel will need the contract, records of performance, and the complete payment history. Keep the conditional check and its correspondence in that file. Before depositing it, confirm whether you are willing to accept the settlement the customer is proposing.
