A contract and an unpaid invoice do not, by themselves, explain every amount in a commercial claim. Start with a separate evidence file for each obligation, alleged breach and loss. This guide concerns preparing that file for a Saudi dispute; the applicable contract, procedural rules and any special legislation still need examination.
What must the file explain?
Identify who promised what, when performance became due, what actually happened and how the event caused the amount claimed. Keep a claim for the contract price distinct from a claim for damages. A disputed invoice may concern whether payment became due, while a damages claim raises additional questions about loss and its cause.
1. Establish the obligation and the authorised parties
Keep the signed agreement, schedules, accepted quotation, purchase orders and later amendments together. Record the contracting entity’s name and the signatory’s authority. If specifications or dates changed, identify the accepted version and evidence of the change; a draft or one party’s internal note does not necessarily establish agreement.
The Evidence Law governs proof. Article 66 addresses writing for transactions exceeding SAR 100,000 or of unspecified value, subject to the applicable exceptions. Do not equate a missing paper signature with the absence of all admissible evidence: preserve the original digital records and examine their attribution and legal status.
2. Build a dated performance record
List the contractual due date, actual delivery, inspection, acceptance or rejection, and any cure period. Attach the record supporting each entry. Distinguish a delivery receipt from technical acceptance, and distinguish acceptance of one instalment from acceptance of the whole project.
For a delay allegation, record dependencies such as site access, approved drawings, advance payments and change orders. A supplier’s late delivery and a customer’s late approval may both matter; the chronology should expose those issues before the claim is quantified.
3. Preserve notice and the response
Keep the notice as sent, its attachments, recipient details and evidence of delivery. Check the contract and the relevant statutory notice rules before assuming that an email, invoice or demand satisfies every requirement. Record any admission, objection, offer to cure or agreed extension without removing the surrounding correspondence.
4. Explain the loss, cause and calculation separately
For each amount, record its legal basis, calculation, supporting document and connection to the alleged breach. A replacement supplier’s invoice may support an additional cost, but the file should also explain why replacement was needed, why the cost was reasonable and whether anything was saved or recovered.
A lost-profit request needs evidence supporting the opportunity and the calculation; projected revenue is not automatically net lost profit. Identify alternative causes and reasonable steps taken to limit loss. Under Civil Transactions Law Article 180, ordinary contractual foreseeability limits require attention, with a distinct rule where fraud or gross fault is established.
5. Review an agreed-compensation clause on its own terms
Identify the obligation covered by the clause and avoid adding the same loss twice. Articles 178–179 distinguish eligible agreed compensation from a clause concerning a monetary obligation, and regulate absence of harm and judicial adjustment. The contract figure alone does not settle every defence or request for an increase.
An illustrative claim schedule
- Outstanding price: contract milestone, acceptance record, invoice and payments already credited.
- Replacement cost: original price, replacement purchase, reason for replacement and the additional cost actually claimed.
- Lost profit: identified transaction, evidence of likely completion, relevant costs and the causal explanation.
- Agreed compensation: clause, covered breach, calculation period and any adjustment issue.
This is a preparation example, not a reported judgment or a statement that every item is recoverable. Remove overlapping amounts and identify evidence still missing.
How does the same file help a defendant?
Respond to each component: whether the obligation existed, whether it was due, whether performance occurred, who caused any interruption and whether the claimed amount is supported. Preserve favourable and unfavourable documents. A focused response can admit an undisputed payment while contesting an unsupported loss calculation.
Before taking the next step
Prepare the contract bundle, chronology, notices, payment ledger and itemised calculation. Check the dispute clause, competent forum and applicable filing requirements promptly. For the legal overview, read contractual liability in commercial transactions. For review of a Saudi matter, use the Saudi contact route and describe the dispute without posting confidential documents publicly.
