Architect Contract Template India — Free Letter of Appointment (COA-Aligned)
By ArchiEaseLast reviewed 30 October 20268 min read
The architect's letter of appointment is the contract. Once signed, it governs the entire engagement: scope, fee, payment schedule, IP, and termination. The template below is built on the Council of Architecture's own Conditions of Engagement: it follows the 7 stages, the payment schedule, the client's responsibilities, reimbursables, termination and arbitration clauses as the Council published them, and has the acceptance block your COA registration number must appear on. Copy it, fill in the highlighted fields, and send.
When to use this template
Use this for any new architecture or interior design engagement in India — residential, commercial, or institutional. It covers the standard case: full architectural services across all 7 COA stages. If you are being appointed for partial services only (e.g., working drawings only), mark the excluded stages as such in Section 2.
For very large projects (fee over ₹25 lakh), have a lawyer review before signing. For standard studio work, this template is sufficient.
The template
Replace every highlighted field with your project's details. The stages, payment percentages and clauses below follow the Council's published Conditions of Engagement. Check the current COA document before changing them.

6. Reimbursable Expenses
In addition to the fee and documentation charges, the Client shall reimburse the Architect at actual cost:
— Travel (to and fro), boarding, lodging and local transport for visits by the Architect's staff to the site or other place necessary for the work
— Presentation models, computer simulation, presentation drawings and similar items prepared at the Client's instance for purposes other than the design and execution of the project
The Architect will supply up to six sets of drawings at different stages free of cost. Fees of consultants, statutory authorities and contractors are the Client's direct responsibility.
7. Ownership of Copyright
Architectural design is the intellectual property of the Architect. The drawings, specifications, documents and models are the Architect's property whether or not the project is executed. The Client may retain copies for information and use in connection with this project and shall not use them for any other project or allow any other person to do so, except for repetition as the Scale of Charges stipulates.
8. Termination
Either party may terminate this appointment by giving the other not less than 30 days' written notice if the other substantially fails to perform its responsibilities and the failure is not caused by the party giving notice. Where the termination is not attributable to any act, omission, neglect or default of the Architect, the Architect is entitled to the fees for the work done under the payment schedule and to the further sums under clauses 9.09 and 9.11 of the Conditions of Engagement. If the Client terminates, the Client may employ another Architect to complete the work after paying the previous Architect's firm.

Have a lawyer confirm this clause suits the project and state before signing.

How to customise this template
Fill in the project particulars first
The estimated cost of works drives every fee calculation in this contract. Use the client's budget — not your estimate of what it will actually cost. The fee is regularised at close-out against the actual cost, so using the budget figure protects you if costs increase.
Choose the right fee percentage
Use the current COA Scale of Charges to identify the correct category and scope. Its explanatory notes say fees for works costing up to ₹15 lakh may be negotiable. Have the completed appointment reviewed before issuing it.
Adjust the payment schedule percentages
The COA schedule uses cumulative percentages of the total fees: retainer, then 10%, 20%, 30%, 35%, 45%, 55%, 65% and up to 90% on virtual completion, with 100% at Stage 7. If you are not doing every stage, or the client has agreed a different split, change the schedule and record it in writing.
Mark excluded stages clearly
If you are not handling statutory approvals (Stage 3) — for example because the client has a separate liaison consultant — mark it excluded in Section 2 and adjust the payment schedule in Section 4 to match the stages you are doing.
Check your GSTIN is current
Your COA registration number and GSTIN must both appear in the acceptance block. A contract without your COA number cannot establish your standing as a registered architect if there is a dispute.
Not sure what fee to charge? Use the COA fee calculator and rates guide — it covers all 13 project categories with worked examples for ₹25L, ₹50L, ₹1Cr and ₹2Cr builds.
Three things architects get wrong in contracts
1. No scope exclusion list
The most common contract dispute in Indian architectural practice is over what was and was not included. If your contract does not explicitly say "structural drawings are excluded," you will be expected to provide them. List every exclusion you can think of in Section 2.
2. Skipping the retainer
Many architects start work without collecting the appointment retainer. The COA schedule's retainer on signing (₹20,000 or 5% of the total fees, whichever is higher) serves two purposes: it confirms the client is serious, and it covers your initial Concept Design work even if the project is cancelled. Do not waive it.
3. Missing the close-out regularisation clause
Under the COA conditions the fee is computed on the actual cost of works on completion, not the initial estimate. Section 3 says so — this means if the build costs ₹1.2Cr instead of the estimated ₹80L, the fee is adjusted at Stage 7. Without this stated in the contract, collecting that balance is difficult.
Frequently Asked Questions
What is an architect letter of appointment in India?
A letter of appointment is the contract between an architect and client. It sets out the scope of services (aligned to COA's 7 project stages), professional fee, payment schedule, copyright and termination terms. Once signed by both parties it is a binding agreement. It should refer to the COA Conditions of Engagement and Scale of Charges.
Does an architect contract need to be on stamp paper?
Stamp-duty, notarisation, and enforceability requirements depend on the state and the agreement. Ask a local advocate to review the final appointment letter before it is signed.
Can a client change the scope of work after signing?
Yes, but any change should be documented as a written amendment to the original appointment letter. Under the COA conditions, revisions to approved drawings required by the client are additional services paid at 50% of the fee for the relevant stage; Section 5 of the template says so. Never accept verbal scope changes — always confirm in writing.
Who owns the drawings after the project is complete?
The COA Conditions of Engagement state that architectural design is the intellectual property of the architect, whether or not the project is executed, and that the client may keep copies for use in connection with the project only. Section 7 of the template above covers this.
What is the minimum architect fee in India under COA rules?
The COA's published minimum under its Scale of Charges is 7.5% for an individual or independent house and 5% for all non-housing projects. A further 10% of the professional fee is charged as documentation and communication charges. The Council describes the scale as a mandatory minimum for registered architects; check the current COA document, and its legal status, before agreeing a lower fee.
