Construction & Contracting Law in Iran

Construction and contracting projects in Iran require careful handling of contract terms, timelines, payment certificates, delays, guarantees, termination rights, and project claims. Because these projects typically involve multiple parties working over an extended period, a single ambiguous clause can turn into a costly dispute long after the contract was originally signed.

Milani Law Firm is an established law firm in Iran, based in Tehran, with a team of business lawyers in Iran advising employers, contractors, consultants, investors, and foreign project participants on construction and contracting law in Iran. The firm’s English-speaking lawyers help clients manage risk, document claims, negotiate disputes, and pursue or defend legal remedies where needed, from the earliest stages of a project through to its completion.

What Does Construction and Contracting Law in Iran Involve?

This area of practice typically involves:

• Drafting and review of construction and contracting agreements before execution
• Interpretation of scope of work, technical specifications, and schedule obligations
• Payment certificates and disputes over amounts approved or withheld
• Delay claims, including questions of responsibility and entitlement to extension of time
• Performance guarantees, advance payment guarantees, and bonds
• Termination rights and the consequences of ending a contract early
• Project claims connected to variations, additional work, or changed conditions

Because construction and contracting law in Iran spans the entire life of a project, the relevant issues shift considerably between the drafting stage, execution, and any dispute that follows.

Who Is This Service For?

This service is typically relevant for:

For any of these participants, disputes connected to construction and contracting law in Iran often arise not from a single event, but from a pattern of unresolved issues that accumulate over the life of a project.

Delay, Payment Certificates, and Contractual Claims

Delay is one of the most common sources of dispute between employers and contractors. Whether a delay is excusable, and whether it entitles the contractor to an extension of time or additional compensation, depends on the cause of the delay, the terms of the contract, and how well it was documented as it occurred. Payment certificates raise a related but distinct set of issues, particularly when an employer withholds or reduces payment based on a dispute over work quality, quantity, or completion status. Maintaining clear records and formal correspondence throughout the project is often what determines whether a later claim can be substantiated.

Guarantees and Termination Rights

Performance guarantees, advance payment guarantees, and similar instruments are intended to secure a party’s obligations, but disputes frequently arise over the conditions under which they can be called or must be released. Termination, whether initiated by the employer or the contractor, typically triggers its own set of obligations regarding outstanding payments, guarantees, and the settlement of work already performed. Reviewing the precise contractual conditions for termination and guarantee release, before taking action, helps prevent claims and counterclaims from prolonging the dispute unnecessarily.

Choosing Between Negotiation, Arbitration, and Litigation

Not every construction dispute needs to follow the same path. In many cases, a structured negotiation, supported by well-documented claims, is enough to resolve a disagreement without further escalation. Where the underlying contract includes an arbitration clause, or where the scale and complexity of the dispute call for it, arbitration is often the more practical route. In the absence of an arbitration agreement, litigation before the competent courts remains the applicable mechanism. The right path depends on the contract, the relationship between the parties, and the nature of the claim involved.

When to Seek Legal Advice on a Construction Matter

Legal advice is particularly useful before signing a significant construction or contracting agreement, as soon as a delay or payment dispute begins to emerge, and before issuing or responding to a notice of termination. Engaging Milani Law Firm’s lawyers early in a matter involving construction and contracting law in Iran generally allows for better-documented claims and a more informed choice between negotiation, arbitration, or litigation.
