Five Financial Mistakes That Weaken Your Position in a Commercial Dispute

Financial mistakes in a commercial dispute — accounting expert matching invoices to delivery notes — Abdelhamid & Co Sharjah

Financial mistakes in a commercial dispute weaken a claimant's position even where the claim is sound on the merits. The recurring failures are invoices without proof of delivery, unreconciled statements of account, undocumented payments, company accounts mixed with the owner's, and a claim submitted without a line-by-line schedule. Abdelhamid & Co (MOE LC0106-01) prepares the financial file.

Why financial mistakes in a commercial dispute decide the outcome

UAE courts refer financial disputes to a court-appointed accounting expert. The expert builds the report on the documents submitted and excludes every amount not matched by supporting evidence.

The claim is therefore measured by the quality of its documentation, not by its merits alone. Claimants lose entire heads of claim where they cannot tie a figure to its supporting document.

The sections below set out five recurring mistakes with the corrective step for each.

Mistake 1: invoices without proof of delivery

An invoice evidences the seller's demand. It does not by itself evidence that the buyer received the goods or services. The appointed expert asks for a delivery document against each invoice.

UAE practice accepts the following as proof of delivery:

  • A delivery note signed and stamped by the buyer or an authorised representative.
  • A bill of lading or warehouse release order in the buyer's name.
  • A works acceptance minute or completion certificate in construction and services contracts.
  • Email correspondence in which the buyer acknowledges receipt or requests a variation.

Correct this before filing by scheduling the unsupported invoices and seeking a written acknowledgment of receipt from the customer.

Mistake 2: unreconciled statements and undocumented payments

A statement of account shows the movement of the debt from inception to the claim date. The expert asks for a statement signed by both parties, or one confirmed by correspondence.

These findings appear in most files that reach the expert stage:

  • A statement produced by the claimant's own system with no signature or acknowledgment from the defendant.
  • Cash receipts taken without a numbered and signed receipt voucher.
  • Payments allocated to invoices other than those the customer intended, opening a dispute over allocation.
  • Cheques recorded without the cheque number, bank and due date.
  • Incoming bank transfers not matched to any specific invoice.

Correct this by preparing a monthly reconciliation between the statement and bank movements, and allocating each payment to the invoice it settled.

Mistake 3: mixing company accounts with the owner's

Mixing the two weakens the company's position before the expert and the court. The opponent argues that the claim belongs to the owner personally rather than to the legal entity with standing to sue.

The mixing shows up as:

  • Customer payments collected into the owner's personal bank account.
  • Company expenses paid from the owner's account without a partner current account entry.
  • Invoices issued in the owner's name for supplies the company delivered.
  • Contracts signed by the owner personally without stating his capacity as company representative.

The mixing also carries a tax effect, because Federal Decree-Law No. 47 of 2022 on Corporate Tax distinguishes between a natural person and a juridical person in determining taxable income.

Mistake 4: a claim without a schedule tied to documents

The appointed expert rejects a claim submitted as a lump sum with no breakdown. The expert requires a schedule showing, for each item, the invoice number, its date, its amount, the supporting document, and the exhibit number in the case file.

A sound technical schedule contains these columns:

  • Item sequence, invoice number and invoice date.
  • Amount before tax, VAT amount and total.
  • Delivery note number and date.
  • Payments received against the item with dates and receipt numbers.
  • Balance claimed and the corresponding exhibit reference.

This schedule shortens the expert stage and reduces the risk of items being excluded for unclear support.

Mistake 5: ignoring credits and set-off, and weak terms of reference

Some claimants submit the gross value of invoices without deducting returns, discounts and credit notes. The expert finds these items in the defendant's books, and the whole claim loses credibility.

Defendants routinely raise set-off for amounts the claimant owes them. Prepare for that plea by scheduling mutual balances with the opponent before filing.

The drafting of the expert's terms of reference defines the scope of his work. A general formulation such as "state the amount due to the claimant" produces a report that never addresses the actual points in dispute. Sound terms of reference are drafted as specific questions: the value of supplies actually delivered, the value of payments received, and the net balance at a stated date.

Our methodology for preparing the financial file before filing

We perform five steps to prepare a claim before it reaches the expert:

  • Step 1: Schedule the claim item by item from the client's books and fix the period and figures in dispute.
  • Step 2: Link each invoice to its delivery document and schedule the invoices with no supporting document.
  • Step 3: Reconcile payments received against bank statements and allocate each payment to its invoice.
  • Step 4: Deduct returns, discounts and credit notes, and schedule mutual balances in anticipation of a set-off plea.
  • Step 5: Prepare the final technical schedule and draft terms of reference, and hand both to the client's lawyer.

Frequently Asked Questions

Which of the financial mistakes in a commercial dispute damages a claim most?

The absence of delivery evidence against invoices. The appointed expert excludes the amount in full where the claimant cannot show the goods or services reached the defendant, even with an invoice and an accounting entry in place.

Will the expert accept a statement of account produced by the claimant alone?

He accepts it as indicative but not as proof of the debt on its own. He asks for it to be reconciled against the defendant's books, or supported by correspondence in which the defendant acknowledges the balance.

How do financial mistakes in a commercial dispute affect the tax position?

Expert work commonly reveals differences between invoices issued and VAT returns filed. Correcting those differences requires a voluntary disclosure to the Federal Tax Authority for the affected periods.

When should an accountant be engaged?

Before the statement of claim is drafted. Advance preparation establishes the amount that can actually be proved, allows the claim to be adjusted before registration, and avoids claiming a figure the expert will substantially reduce.

What role do the terms of reference play?

They define the scope of the expert's work and the questions he answers. A general formulation produces a report that misses the points in dispute. Sound terms of reference are framed as specific questions about stated values, dates and balances.

Does financial preparation help the defendant too?

Yes. A defendant uses the same documents to prove payment, to show returns and discounts the claimant omitted, and to raise set-off for mutual balances.
