Set-Off in Commercial Debt Claims

Set-Off and Counterclaim Compared

Set-off answers the plaintiff’s claim to the extent available, while a counterclaim can support a separate award in the defendant’s favour. A defendant seeking recovery beyond defeating the debt needs to plead the affirmative relief through the applicable cross-claim procedure.

The basis of set-off changes the facts you must establish. These categories need separate analysis even when pleaded in the alternative.

Bases of Set-Off

For a NSW example, section 21 of the Civil Procedure Act 2005 permits a defence for mutual debts due when the defence is filed. Its definition of debt includes a liquidated claim, meaning an amount fixed or ascertainable without assessing damages. The provision recognises agreements excluding set-off and preserves other rights, including equitable rights. The NSW Judicial Commission’s account of set-off and cross-claims explains this framework.

Equitable set-off can involve damages whose amount still requires assessment. The connection must justify protection against enforcing the plaintiff’s demand without allowing for the cross-demand. Being parties to the same commercial relationship does not itself answer that question. In Kendray v Hassall [2001] NTSC 40, the Northern Territory Supreme Court discusses the connection test at [28] and capacities at [32].

An independently arguable counterclaim can remain available when set-off fails. That does not automatically suspend the plaintiff’s claim or establish a right to withhold payment.

Read the Contract and Match the Claims

Read the payment and set-off terms against the identity and capacity of each creditor and debtor. Record the governing law and forum before applying a jurisdiction’s statutory or pleading rules.

Start with the executed agreement and any variations. A set-off clause defines when a party can deduct a cross-demand from a payment. Its scope can depend on the type of claim, whether the amount must be agreed and any notice procedure. A no-set-off term instead requires payment without the deductions it excludes. Preserve the exact wording beside the schedule’s legal assumptions.

For illustration, permission to deduct an agreed credit would not, on those words alone, establish permission to deduct disputed damages. A term requiring payment without set-off raises a different question about exclusions. Analyse its coverage of the pleaded basis and any legislation that prevents the exclusion. Do not assume a clause overrides a mandatory statutory regime.

Match the claims using the following checks.

• Identify the actual contracting entities. A director’s personal claim and a company’s invoice require separate analysis.
• Record each capacity, including trustee or representative capacities. Similar names do not establish interchangeable rights.
• Identify the work or transaction behind each demand and the facts connecting them for an equitable defence.
• Locate any assignment, settlement or variation affecting who owns the demand or what remains payable.

A bank’s combination of accounts is a separate exercise of banking rights. It applies a customer’s credit balance against debt owed to the bank, subject to the relevant legal basis and terms. It is different from pleading a customer’s commercial damages claim against a supplier. Before accepting a bank deduction in the schedule, identify the account holders, their capacities and the authority for the entry. The Banking Code’s account-combination provisions also address notification and restrictions for participating banks.

Build the Competing Balance Schedules

Build a debt schedule and a separate cross-demand schedule, then show the balance under each legal outcome. Give every entry a document reference and keep payments separate from disputed loss.

Use an invoice register with distinct columns for invoices, credits, payments and interest. Use a linked cross-demand register with the alleged breach, loss calculation and supporting records. A single net figure hides which deductions are accepted and which depend on a successful defence.

Fictional Invoice and Cross-Demand Schedule

Assume a $60,000 invoice for services and a disputed $15,000 loss claim about their performance. No payment or agreed credit has yet been applied. Interest is excluded from these principal-only balances and must be calculated separately if claimed.

The invoice balance is $60,000 before set-off. If the full cross-demand is established and available as set-off, the alternative principal balance is $45,000. If set-off is unavailable, retain the $60,000 debt position and the separate disputed $15,000 counterclaim. These are competing positions, not a finding about entitlement.

For interest, add a separate schedule showing the asserted contractual or statutory basis, rate and period. Show how each alternative treatment affects the calculation. Deducting $15,000 from principal does not itself determine when interest changes.

Bank statement reconciliation helps establish receipts and the ledger balance. The legal analysis decides whether the cross-demand can reduce recovery. Keep an agreed invoice credit visible so a loss calculation cannot claim that same adjustment again.

FinTrace saves lawyers and forensic accountants hours of statement conversion and review when payment records span a large bundle. Its searchable Excel ledger brings transactions across supplied accounts together with source references. This gives the team direct access to the payment evidence while it prepares the competing schedules.

Plead and Update the Position

Plead the facts supporting the selected basis of set-off and preserve the alternative counterclaim where separate relief is sought. Use the rules of the court hearing the claim.

In NSW statement-of-claim proceedings, Uniform Civil Procedure Rules rule 14.7 requires material facts, while rule 15.1 requires particulars identifying the case to meet. Rule 14.14 addresses matters requiring specific pleading. The Judicial Commission’s pleading guidance also explains rule 14.13’s restriction on pleading an amount for unliquidated damages. A private loss estimate in a schedule is not permission to plead damages as a fixed debt.

For contractual set-off, plead the agreement’s material effect and the facts satisfying its conditions. For legal set-off, identify the mutual debts and the facts establishing their amount and due status. An equitable defence needs the underlying actionable cross-demand and the facts making enforcement without allowance unjust. The independent counterclaim needs its own cause of action and relief.

Update both schedules after receipts, credits or settlements. In the fictional example, suppose a later $10,000 payment is allocated wholly to invoice principal. The debt balance becomes $50,000. Applying the disputed $15,000 once produces an alternative principal balance of $35,000, if set-off succeeds. Subtracting it again from $35,000 would double count the defence.

Incorrect treatment records a $15,000 settlement credit against the invoice and deducts the same settled loss again as set-off. Correct treatment records how the settlement resolves that cross-demand, then carries only any genuinely remaining disputed amount.

Before settling the amount claimed, reconcile every receipt to its allocation and trace each adjustment to its source. The final schedules must explain the remaining debt, the separate cross-demand and the alternative balance using the same records.
