The general rule governing all contracts is that they are binding; the contract is the <\/span>“Law of the Contracting Parties”<\/b> (<\/span>Pacta Sunt Servanda<\/span><\/i>). Both parties are obligated to honor their agreements, a principle that fortifies the contractual bond with legal force and legitimate stability. However, practical reality and the necessity of business continuity\u2014coupled with fluctuating economic conditions\u2014may compel parties to amend a contract after execution.<\/span><\/p>\n

This raises a critical question: Can contracts be amended after they are signed? Can one party amend a contract unilaterally? In this article, <\/span>Al-Salama Law Firm & Legal Consultations<\/b> answers these questions and provides the correct legal characterization.<\/span><\/p>\n

 <\/p>\n

I. The Contract is the Law of the Contracting Parties<\/b><\/h2>\n

The principle of <\/span>Pacta Sunt Servanda<\/span><\/i> is a cornerstone of civil law. Its essence lies in the <\/span>binding force<\/b> of the contract, dictates that the parties are bound by every provision therein. It imposes a mandatory duty of compliance, meaning neither party may rescind or amend the agreement unless permitted by the agreement itself or by law.<\/span><\/p>\n

However, like all legal principles, this one is subject to exceptions. This is where the answer to our query lies: contracts <\/span>can<\/b> be amended post-execution under specific exceptions arising from the principle itself. These exceptions may be <\/span>consensual<\/b> (by agreement) or <\/span>statutory<\/b> (by operation of law). This is codified in <\/span>Article (94\/1)<\/b> of the Civil Transactions Law: <\/span>“If a contract is validly concluded, it may not be rescinded or amended except by agreement or pursuant to a statutory provision.”<\/span><\/i><\/p>\n

 <\/p>\n

II. Amendment by Mutual Consent<\/b><\/h2>\n

Under the binding force of the contract, adherence to all terms is the default. Nevertheless, the Law grants parties full flexibility to amend contractual terms post-signature, provided there is <\/span>mutual consent<\/b> (<\/span>consensus ad idem<\/span><\/i>). To ensure full legal protection, such amendments should be executed via a <\/span>Contractual Addendum (Appendix)<\/b>, which becomes an integral and inseparable part of the original agreement, detailing the new developments agreed upon.<\/span><\/p>\n

We advise investors and business owners, particularly in construction (FIDIC\/EPC), to include <\/span>“Economic Rebalancing”<\/b> or <\/span>“Price Adjustment”<\/b> clauses from the outset. These clauses grant a legal right to renegotiate values and execution schedules upon specific economic triggers, such as fluctuations in raw material prices or changes in tax policy. Incorporating clear amendment mechanisms turns the contract into a flexible economic instrument that adapts to market shifts without resorting to litigation. With 12 years of expertise, <\/span>Al-Salama Law Firm<\/b> specializes in drafting such resilient frameworks.<\/span><\/p>\n

 <\/p>\n

III. Statutory Grounds for Unilateral Amendment<\/b><\/h2>\n

The Civil Transactions Law specifies instances where a contract may be amended without the other party’s consent:<\/span><\/p>\n

1. Amendment Due to Exceptional Circumstances (Hardship)<\/b><\/h4>\n

Article (97)<\/b> of the Law provides:<\/span><\/p>\n

    \n
  1. If general exceptional circumstances arise that could not have been foreseen at the time of contracting, rendering the performance of the contractual obligation onerous for the debtor such that it threatens them with a gross loss, the debtor may\u2014without unjustified delay\u2014invite the other party to negotiate.<\/span><\/li>\n
  2. A request for negotiation does not entitle the debtor to cease performance.<\/span><\/li>\n
  3. If no agreement is reached within a reasonable period, the court may, depending on the circumstances and after balancing the interests of both parties, reduce the onerous obligation to a reasonable limit.<\/span><\/li>\n
  4. Any agreement to the contrary shall be void.<\/span><\/li>\n<\/ol>\n
