Someone forged my digital signature on a document, what law applies?

Question

I discovered that my digital signature or electronic signature was used on a document/contract without my authorisation. I have been reading conflicting things online and I would like to understand what Indian law actually says about this, which Act and Section applies, what the realistic timelines and costs are, and what I should be doing right now to protect my position. If the matter can be resolved without litigation I would prefer that route, but I want to know what my rights are before I agree to anything or sign any document.

Someone forged my digital signature on a document, what law applies? is governed in India primarily by Information Technology Act, 2000 – Section 66C, Information Technology Act, 2000 – Section 73, Bharatiya Nyaya Sanhita, 2023 – Section 336 (forgery) and Information Technology Act, 2000 – Section 3. The short answer is set out below, followed by the practical steps most people in this situation need to take. Read it alongside the specific provisions named, because the exact relief available to you turns on the facts you can prove on paper.

Unauthorised use of your digital signature/electronic signature certificate is identity theft under Section 66C of the IT Act, punishable with imprisonment up to 3 years and fine up to Rs 1 lakh.

Publishing a digital signature certificate that is false in a material particular, or knowing it to be suspended/revoked, is separately punishable under Section 73 of the IT Act.

Since a document with a forged signature is a forged 'electronic record' under Section 4 of the IT Act (which gives electronic records legal recognition), general forgery provisions under Section 336 of the Bharatiya Nyaya Sanhita, 2023 (replacing IPC 463-465) also apply, with punishment depending on the nature of the document forged.

Contact your Certifying Authority (CA) immediately to revoke/suspend the compromised Digital Signature Certificate (DSC) under Section 38 of the IT Act, which stops further misuse while your complaint is investigated.

Where the forged signature was used to execute a contract or transfer property/money, the underlying transaction can be challenged as void/voidable in civil court in addition to pursuing the criminal complaint.

What to do next: 1) Contact your Certifying Authority to immediately revoke the compromised DSC; 2) File a police complaint citing Sections 66C IT Act and Section 336 BNS; 3) Notify any counterparties of the forged document and dispute the transaction in writing; 4) Consult a lawyer to challenge any contract/transaction executed using the forged signature.

If the other side has already issued a notice, filed a case or set a deadline, treat the matter as time-sensitive — most remedies under Information Technology Act, 2000 – Section 66C carry limitation periods, and a delay you cannot explain weakens an otherwise strong case.
