An interior design contract should clearly explain the work, fees, responsibilities and project timeline before work begins. Use this checklist to review deliverables, payment terms, changes, materials, cancellation clauses and other essential details before signing.

Hiring an interior designer is an exciting step towards creating a home that reflects your lifestyle, preferences and budget. But before discussing finishes, furniture and colour palettes, there is one document worth reading carefully: the contract.

A designer’s proposal may look straightforward, yet important details can remain unclear. Does the quoted fee cover only design concepts, or does it include site supervision? How many design revisions are allowed? Who pays vendors? What happens if the project runs over budget or either party wants to end the agreement?

These questions are easier to resolve before work starts than after a disagreement arises.

A well-written interior design contract should explain what the designer will deliver, what the homeowner must provide, how payments work, and how changes or delays will be handled.

Here is a practical checklist to help you review the agreement before signing.

1. Confirm Who You Are Hiring and What the Contract Covers

Begin with the basic details. Check the full legal name of the designer or design firm, the contracting party’s address and contact information, and the address of the property being designed.

If you are hiring a firm, clarify whether the agreement is with the firm itself or with an individual. The person discussing the project may not necessarily be the party responsible under the contract.

Make sure the document identifies the project, its expected starting date and the services being engaged. If the scope covers only selected rooms, list those rooms rather than relying on a general description such as “complete home interiors.”

Also check whether the agreement is a design-services contract, an execution contract, or a combined arrangement. These can involve different responsibilities.

2. Read the Scope of Work and Deliverables Carefully

The scope of work is one of the most important parts of the agreement. It should describe what the designer is actually expected to do.

Depending on your project, the deliverables may include:

  • Initial consultation, measurements and space planning.
  • Design concepts, mood boards and material recommendations.
  • Floor plans, furniture layouts and technical drawings.
  • Three-dimensional visualisations or rendered views.
  • Material specifications, finish schedules and a bill of quantities.
  • Vendor coordination, site visits or execution supervision.

Do not assume that every service is included simply because it was discussed during a meeting.

For example, a designer may provide a layout and visualisations without managing contractors or visiting the site regularly. Another professional may offer end-to-end coordination. Both arrangements can be valid, but the written scope should make the difference clear.

Check the format of the deliverables, when they will be provided and which stages require your approval. If a particular drawing, specification or handover document is important to you, make sure it is named in the contract.

3. Understand the Design Fee, Budget and Exclusions

The total figure in a proposal does not always represent the complete amount you will spend on the project.

First, establish how the designer calculates the fee. It may be a fixed amount, a percentage of the project cost, a rate based on area, an hourly charge or a combination of methods. Ask what the fee includes and what may be billed separately.

Then review the treatment of taxes, consultation charges, travel, site visits, procurement services, third-party consultants and any other reimbursable expenses. Confirm whether applicable taxes are included or charged separately.

Most importantly, distinguish the designer’s fee from the estimated cost of executing the interiors.

A design-services fee may not include furniture, materials, contractor labour, electrical work, plumbing, civil modifications, transport, installation or vendor charges. The agreement should identify these exclusions as clearly as the included services.

Ask whether the overall project budget is an estimate, a fixed-price commitment for specified work, or a preliminary allowance. If the design changes or material prices vary, understand how the budget will be revised.

A realistic contract makes it easier to compare the proposal with your budget without assuming that every possible cost is already covered.

4. Check the Payment Schedule and Milestones

Before paying an advance, understand when each subsequent payment becomes due and what it corresponds to.

A payment schedule might be linked to the start of the project, approval of the design concept, completion of drawings, procurement, installation or agreed project milestones. The appropriate structure depends on the services and the way the project is being delivered.

Check the following details:

  • The advance amount and when it is payable.
  • Each milestone, its associated payment and the expected deliverable.
  • Invoice requirements and payment due dates.
  • Whether taxes and approved expenses are charged separately.
  • The consequences of delayed payments or paused work.
  • The treatment of unused advances, deposits and purchases if the project ends early.

Avoid relying on an informal promise that payments can be sorted out later. The schedule should be documented so both parties understand when money is due and what work or service it relates to.

Also clarify who receives money intended for materials and vendors. Payments to the designer, a contractor and a supplier may be governed by different arrangements. Request appropriate invoices or receipts for project purchases.

5. Confirm the Timeline and How Delays Will Be Handled

A project timeline should be realistic and connected to the work being promised.

Look for expected dates or durations for design concepts, revisions, technical drawings, material selections and other agreed stages. If execution is included, check whether the agreement provides an estimated overall schedule and identifies the major dependencies.

Some delays may be outside the designer’s direct control. Homeowner approvals, building-society permissions, site readiness, supplier lead times, contractor availability and unexpected site conditions can all affect progress.

The contract should explain how delays will be communicated, how revised dates will be agreed, and what happens when one party does not provide a required approval or deliverable on time.

If there is a firm completion date that matters to you, discuss it explicitly. Do not assume that a tentative date on a presentation or verbal assurance automatically has the same status as a documented contractual commitment.

6. Understand Revisions, Changes and Additional Charges

Interior design is collaborative, so changes are possible. The important question is how they will be managed.

Check how many rounds of revisions are included at each stage, what qualifies as a revision, and when a request may be treated as additional work.

For example, adjusting a colour or moving a furniture item during the agreed concept stage may be treated differently from redesigning a room after drawings have been approved or changing the material specification after an order has been placed.

The agreement should identify how extra charges are calculated and how additional time or procurement costs will be handled.

Agree on a written approval process for changes. Before authorising extra work, request confirmation of the revised cost, its effect on the timeline and any associated material or contractor implications.

Keeping a written record helps prevent misunderstandings about whether a change was included in the original fee.

7. Clarify Materials, Procurement and Vendor Responsibilities

If your designer is helping purchase products or manage vendors, establish exactly what that responsibility includes.

The contract should clarify who selects and approves materials, who places orders, who pays suppliers, and who is responsible for checking deliveries. It should also explain how unavailable products, substitutions, damaged items or changing prices will be handled.

Ask whether the designer charges a procurement fee, markup or commission, and how that charge is disclosed. Clarify whether vendor contracts are made directly with you or through the designer or design firm.

Confirm what records you will receive for major purchases, including invoices, product details and warranty information where applicable. Find out who will coordinate a defect or warranty claim after installation.

If you are expected to purchase certain products yourself, make a clear list of owner-supplied items and confirm when they need to be available on site.

8. Define Site Visits, Supervision and Each Party’s Responsibilities

Words such as “project management,” “site supervision” and “turnkey interiors” can mean different things in different proposals.

Ask what the designer is responsible for during execution. Does the role include scheduled site visits, contractor coordination, inspection of work against drawings, progress updates, quality observations or approval of material samples? How often will visits take place, and who will report issues?

Also identify responsibilities that remain with the homeowner or other professionals. These could include access to the property, timely decisions, payments to contractors, building-society permissions, approvals for structural or services-related work, and the appointment of appropriately qualified technical professionals.

If the project includes civil, electrical, plumbing or other specialist work, clarify who prepares or approves the relevant technical details and who is responsible for carrying out the work.

A designer’s involvement in a project should not be assumed to replace the duties of contractors, engineers or other professionals unless the contract clearly provides for the relevant responsibilities.

9. Read the Cancellation, Termination and Dispute Clauses

No one plans for a project to break down, but the agreement should explain what happens if it does.

Check whether either party can end the contract, what notice is required and whether there are specified reasons or conditions for termination. The terms should explain how completed services will be valued, which expenses remain payable, how committed vendor orders will be handled and whether any portion of an advance may be refundable.

Look for provisions covering extended pauses, failure to pay, failure to deliver agreed services and circumstances outside either party’s reasonable control. Make sure you understand the consequences before signing.

The dispute clause deserves attention too. Check how disagreements are expected to be raised and resolved, whether the agreement specifies a process for escalation or mediation, and what governing law or jurisdiction is named where relevant.

Clauses dealing with liability, indemnity, penalties, termination payments or dispute resolution can have significant consequences. Do not rely on a heading alone to understand what they mean.

10. Check Ownership of Drawings, Plans and Project Photographs

Design documents can be important long after the first installation is completed.

The agreement should explain what happens to the drawings, specifications, visualisations and other project files created by the designer. Clarify which documents you will receive, in what format, and whether editable source files are included or charged separately.

Also understand the difference between receiving a copy of a design document and having the right to reuse, modify, reproduce or share it. The contract should address those rights in understandable terms.

If you expect to use the drawings with another contractor or for future changes, discuss that use before signing.

Photographs of the completed project are another detail worth clarifying. Ask whether the designer may photograph your home or publish images in a portfolio or on social media, and whether your permission is needed. If privacy is important, agree on the conditions in writing.

A Final Contract Checklist Before You Sign

Before approving the agreement, confirm that you have:

  1. Checked that the correct parties, property address and rooms are identified.
  2. Reviewed the scope, deliverables and exclusions in writing.
  3. Distinguished design fees, taxes, reimbursable expenses and execution costs.
  4. Confirmed payment amounts, milestones, invoices and due dates.
  5. Understood the timeline and process for communicating delays.
  6. Checked revision limits, change requests and additional charges.
  7. Clarified material selection, vendor payments, warranties and procurement fees.
  8. Defined site visits, supervision and other professional responsibilities.
  9. Reviewed cancellation, refunds, termination and dispute procedures.
  10. Clarified ownership of design documents and permission for project photography.

Read the agreement alongside the proposal, quotation, scope document and any annexures it refers to. If the contract says a document forms part of the agreement, make sure you have received and reviewed it.

Do not sign a blank or incomplete document, and ask for corrections to be made in writing. Keep the final signed version and related approvals, invoices and change records together.

This checklist provides general guidance, not legal advice. For a high-value project or any clause you do not understand—particularly those concerning liability, intellectual property, penalties or termination—consider getting advice from a qualified lawyer familiar with Indian contracts.

Final Thought

An interior design contract is not merely paperwork to complete before the project starts. It is the document that records what you have agreed to, how decisions will be made and what happens when plans change.

Read beyond the total fee. Confirm deliverables, exclusions, payments, revisions, responsibilities and exit terms. If something important was promised verbally, ask for it to be included in writing before signing.

A beautiful home begins with good design—but a well-understood agreement helps the project begin on the right footing.

Frequently Asked Questions

1. What should an interior designer’s contract include?

It should identify the parties and property, define the scope and deliverables, explain fees and payment milestones, set out timelines and revision limits, and clarify responsibilities for procurement, site visits, changes, termination and dispute resolution.

2. Is the interior design fee the same as the execution cost?

Not necessarily. The design fee may cover consultation, planning, drawings and specified design services, while execution may involve separate charges for materials, furniture, labour, contractors and installation. The contract should explain what is included and excluded.

3. Should I pay the entire interior design fee upfront?

Review the proposed payment schedule and understand which services or milestones each payment covers. There is no single payment structure suitable for every project, so clarify advances, due dates, invoices, refunds and the treatment of committed expenses before paying.

4. What if the interior project cost increases after signing?

Check how the agreement handles changes in design, quantities, material prices and additional work. Ask for revised costs and timeline implications in writing and approve changes before the additional work or purchase is authorised.

5. Can I request design changes after signing the contract?

Usually, changes can be discussed, but whether they are included in the original fee depends on the contract. Check the number of included revision rounds, the stage at which changes become additional work, and the approval process for revised charges.

6. Should a lawyer review an interior designer’s contract?

For a straightforward, clearly written agreement, you may be able to resolve routine questions directly with the designer. For a high-value project or clauses involving liability, indemnity, intellectual property, substantial penalties, termination or disputes, legal review can help you understand the implications before signing.
