Change Order in India: Template and Key Clauses (2026)

A change order in India is the document that records an agreed change to an existing contract: a new scope, a different price, a revised timeline, or all three. It is common in construction, engineering, IT and services work, where the original agreement rarely survives untouched. The question that matters in India is not what to call it but whether the change is validly agreed, properly priced for tax, and stamped where required. This guide sets out the Indian law that applies, the key clauses, and a drafting skeleton. It is general information, not legal advice; take Indian advice before signing a live deal. ## What is a change order in India? A change order, sometimes called a variation or a change request, is a written amendment to a contract already in force. It does not create a new contract from scratch. It modifies the existing one: adding or removing work, adjusting the price, or moving dates. In construction and project contracts it is usually issued under a variations clause in the main agreement, which sets out who can order a change, how it is valued and how the time and cost impact is handled. ## What law governs change orders in India? There is no separate change-order statute. The change is governed by the Indian Contract Act 1872, read with the main contract and a few tax and stamp rules: - Agreement and consideration. Under the Indian Contract Act 1872, a contract can be varied by mutual agreement. Section 62 allows the parties to alter or substitute a contract, and where they do, the original obligations need not be performed. A variation generally needs consideration, so a one-sided change that adds work without any corresponding adjustment can be weak unless the main contract already provides for it.

• The variations clause. Most well-drafted Indian project contracts contain a variations mechanism. If it does, follow it: the change order should be issued and valued as the clause requires. If it does not, the change rests purely on fresh mutual agreement.
• Novation. Where the change is so large that it replaces the original bargain, it may amount to novation under section 62, which discharges the old contract and creates a new one.
• GST. A change in scope or value changes the taxable supply. The revised value attracts Goods and Services Tax at the applicable rate, and the change order should state whether the figures are inclusive or exclusive of GST and address any revised invoicing.
• Stamp duty. An amendment may attract stamp duty. Stamp duty in India is governed by the Indian Stamp Act 1899 as adapted by each state, and the duty on an amendment or supplementary agreement varies from state to state, so confirm the local position. ## Key clauses in an India change order - Reference to the original contract: identify the main contract by date and parties, so the change order clearly amends it.
• Description of the change: the exact scope added, removed or altered.
• Price adjustment: the revised amount, how it was valued, and the GST treatment.
• Time adjustment: any extension of time or revised milestones.
• Effect on the rest of the contract: confirm that all other terms continue unchanged.
• Consideration: make clear what each side gives, so the variation is supported.
• Approvals and authority: who may approve the change on each side.
• Stamping: note that the amendment will be stamped as required in the relevant state.
• Signatures and date. ## Getting the change validly agreed The most common dispute is whether a change was actually agreed or was just extra work someone assumed would be paid for. In India, the safe route is a signed change order issued the way the main contract allows, with a clear price and a clear time impact, before the changed work starts. Where the main contract has a variations clause, use it. Where it does not, record the mutual agreement and the consideration expressly. Verbal instructions to do more work, without a written change order, are a frequent source of unpaid claims. ## A simple drafting skeleton 1. Title and change order number

2. Reference to the original contract (parties and date)
3. Background and reason for the change
4. Description of the change in scope
5. Revised price and GST treatment
6. Revised timeline or extension of time
7. Consideration and confirmation the variation is agreed
8. Effect on remaining terms (all else unchanged)
9. Approvals and authority
10. Stamping note (state stamp duty)
11. Signatures and date ## Common mistakes to avoid - Doing extra work on a verbal instruction, with no signed change order, and then struggling to be paid.

• Ignoring the variations clause in the main contract and inventing a different process.
• Forgetting the GST impact of a changed scope or value.
• Overlooking stamp duty on the amendment, which varies by state under the Indian Stamp Act 1899 as adapted locally. ## Keeping change orders under control If you run many projects, the hard part is not one change order. It is tracking which contracts have been varied, how many times, what the running revised price and timeline are, and which amendments were properly stamped. Drafting from a tuned template, flagging risky clauses, and keeping a clean version history is what an AI contract workspace can hold in one place. Adira is built for this, with per-clause risk review, plain-English clause editing and a live activity timeline that doubles as version history. It is India-first, so Indian contract, GST and stamp-duty context is its home ground. More at Adira. The law above stands on its own. ## Bottom line A change order in India is an amendment to a live contract under the Indian Contract Act 1872. Agree it in writing, support it with consideration, follow the variations clause where there is one, price the GST correctly, and check the state stamp duty on the amendment. Get the change signed before the changed work starts, and take Indian advice on a real deal.
