Who owns the drawings? Copyright and licence in Indian practice

A client asks, usually pleasantly and usually near the end of a project, for the CAD files. Sometimes they want them for a future extension. Sometimes their contractor has asked. Occasionally they are about to build the same house on a second plot and would rather not pay you twice.

Most architects answer this badly, and not because they don't know the law. It's that they've never had to say it out loud. The position is reasonably clear, and being able to state it calmly on the phone is worth more than being right two years later.

What the law protects

The Copyright Act, 1957 treats architecture as an artistic work. Section 2(b) defines a work of architecture as any building or structure having an artistic character or design, or a model of such a building or structure. From there the artistic-works provisions in sections 13 and 14 supply the actual bundle of rights.

Two things follow that architects tend to find counter-intuitive. First, the protection runs to both the drawings and the building — the design as expressed on paper, and the structure as built. Second, it reaches the artistic design and character and stops there. Construction methods, engineering principles and the technical means by which the thing stands up aren't copyright subject matter. You can't copyright a way of building. You can copyright this building.

That boundary explains why so many "they copied my design" conversations go nowhere. A similar structural approach, a comparable planning logic, a shared set of proportions that both of you derived from the same byelaw: none of that is infringement. A recognisable reproduction of the artistic design is a different matter entirely.

Paying for drawings is not buying the copyright

Copyright vests, as a default, in the author of the work. For an architectural work that is the architect who created it. It passes to somebody else only by assignment, and section 19 requires that assignment to be in writing, signed by the assignor or an authorised agent. It also has to identify the work and specify the rights assigned, the duration and the territorial extent. Nothing in that mechanism can be triggered by paying an invoice.

So when a client says "I paid for these drawings, they're mine", both halves of the sentence are true in their own way and the conclusion still doesn't follow. They paid for the drawings. They have the drawings. Absent a written assignment, they don't have the copyright in them.

Which gives you two jobs, both boring and both quick. If you engage people, write down who owns what they draw, and use a written assignment rather than an employment clause for anyone who isn't on your payroll. If you are engaged by someone else's practice, read what you signed. These are documents that stay dull right up until the afternoon they become extremely interesting.

What the licence should say

The clean arrangement isn't an assignment at all. The client receives a licence: permission to use these drawings, for this project, on this plot. You keep the copyright. They get everything they actually need, which in almost every case is less than they asked for.

A licence clause is doing four separate jobs. Spell out each one rather than hoping a single sentence carries all of them.

The trigger row is the one with money in it, and it connects straight to how the practice is paid. A licence that takes effect on payment means very little if the drawings are already sitting in the client's possession either way. That's why the licence position and the stage-wise fee schedule belong in the same conversation, and why issuing drawings on payment does more than protect cash flow. It keeps the licence and the file in step with each other.

Reconstruction is specifically allowed

One statutory exception comes up whenever a building is damaged or altered, so it's worth knowing. Section 52(1)(x) provides that reconstructing a building or structure in accordance with the architectural drawings or plans by reference to which it was originally constructed is not an infringement, where the original construction was made with the consent or licence of the owner of the copyright in those drawings.

In plain terms: if the building was lawfully built from your drawings, rebuilding it from those same drawings doesn't infringe. That's sensible, and it isn't a loophole for putting the design up elsewhere. The exception permits reconstruction of that structure, not replication of the design on a new site.

Moral rights and their limit

Separately from the economic rights, section 57 gives an author special rights that survive assignment: broadly, the right to claim authorship, and the right under section 57(1)(b) to restrain or claim damages for distortion, mutilation or modification of the work that would be prejudicial to honour or reputation. These are the moral rights, and architects place a great deal of hope in them.

That hope needs tempering. In Raj Rewal v. Union of India, decided by the Delhi High Court in 2019 over the demolition of the Hall of Nations at Pragati Maidan, Justice Rajiv Sahai Endlaw considered whether an architect's moral rights could prevent the destruction of a building he had designed, and declined to read section 57 that way. Part of the reasoning was structural: if demolition were prohibited by section 57(1)(b), the reconstruction exception in section 52(1)(x) would be rendered redundant, and no part of a statute should be read so as to make another part otiose.

So the realistic position is that moral rights are strong on attribution and on gross misrepresentation of your work, and weak as a tool for stopping an owner altering or demolishing their own building. Set your expectations accordingly, and put attribution in the contract instead of relying on the statute alone.

Registration is optional, evidence is not

Copyright arises on creation. There's no requirement to register an architectural work for it to be protected, and most architects never do. Registration is available, and under section 48 the Register of Copyrights is prima facie evidence of the particulars entered in it, which can be useful for a competition-winning scheme or a design you expect to license repeatedly.

For everyday practice, though, registration isn't what decides disputes. What decides them is whether you can show what you drew, when you drew it, and what you handed over on which date. That's a record-keeping question rather than a legal one, and it's answerable with things you should be doing anyway.

• Dated issues, with revision and status, in a drawing issue register. The register is the timeline you'll be arguing from.
• Every superseded revision retained rather than overwritten, so the development of the design stays visible. Versioned document sets do this without anyone having to remember to.
• A record of who received what and when, which is what an audit log is for: who, when, and why, on every line.
• A rights line in the title block, so the licence position travels on the drawing itself and not only in a letter nobody has reread since signing.

What to hand over, and what not to

At completion the client is entitled to what the appointment letter says they're entitled to, which is usually the as-built set and the documents needed for the occupation certificate. That's a PDF deliverable. The working files are a separate question and should be treated as one.

Handing over CAD or a model isn't required by default, and doing it casually undercuts everything above, because an editable file is the practical means by which a design gets rebuilt elsewhere. If a client genuinely needs the working files, that's a negotiation with its own fee and its own written licence terms rather than a favour at close-out. The mechanics of who gets which format are covered in sending drawings without losing control of them.

None of this is about being difficult with clients. Almost every client who asks for the files has an entirely ordinary reason and will accept a clear answer without complaint. The trouble comes from architects who have never worked out what their answer is, and end up improvising one at the exact moment they're least inclined to say no.
