Short Definition
An entire agreement clause is a contract term stating that the written contract, with its annexes, is the whole of what the parties agreed on its subject, and that it supersedes all prior negotiations, correspondence, promises and oral or written undertakings not included in it.
Overview
Legal Basis
There is no specific provision on entire agreement clauses; their effect rests on the Civil Transactions Law issued by Royal Decree M/191 dated 29/11/1444H — Article 104 (interpretation; no departure from clear wording), Articles 61–62 (deception and annulment) and Article 173 (no exclusion of liability for fraud or gross negligence) — and on the Evidence Law issued by Royal Decree M/43 dated 26/5/1443H — Article 66 (written proof above SAR 100,000) and Article 67 (no witness testimony against or beyond written evidence).
Practical Example
A company negotiates to rent a showroom in Jeddah at SAR 180,000 a year (plus 15% VAT, i.e. SAR 27,000). During the viewing, the owner’s representative verbally promises to install a new glass frontage at the owner’s expense, worth about SAR 35,000, but the signed lease contains an entire agreement clause and says nothing about the frontage. After opening, the company asks for the frontage; the owner refuses, relying on the clause and on the written contract. Because the promise goes beyond the written contract, the transaction is worth well over SAR 100,000 and there is no written evidence of the promise, the company struggles to prove it through witnesses. The lesson: the frontage belonged in a signed annex. By contrast, if the owner had deliberately concealed that the showroom could not be licensed for the company’s activity, the clause would not stop the company from seeking annulment for deception.
Common Mistakes
- ✗Relying on verbal promises made during a viewing while signing a contract with an entire agreement clause — what is not written is hard to prove.
- ✗Assuming the clause protects against deception or fraud claims — annulment for material deception remains available, and liability for fraud or gross negligence cannot be excluded.
- ✗Drafting the clause so it wipes out annexes or plans meant to survive — list expressly the annexes and drawings that form part of the contract.
- ✗Not updating the contract when a later change is agreed — post-signing amendments need a written, signed annex.
- ✗Copying the clause from foreign templates without adapting it to the Saudi Civil Transactions Law and Evidence Law.
International Differences
The clause originates in common-law systems: in the United States it works alongside the parol evidence rule, and English courts generally enforce it between commercial parties but do not allow it to exclude liability for fraud. In the UAE, Egypt and Turkey the clause is common in commercial contracts, but its reading remains subject to the civil codes’ interpretation rules and good-faith principles. In Saudi Arabia its effect is reinforced by the written-evidence rules of the Evidence Law, while deception and fraud remain outside its protection.
