Common questions
Do I need to visit your Delhi office?
No. The entire process is online. Submit your document and ID via WhatsApp or email, complete the OTP or ID verification step, and receive your signed PDF back on the same channel — from anywhere in the world.
I’m a foreign national or NRI. Can I use this service?
Yes, absolutely. No Aadhaar required. We verify your identity via passport or other valid government-issued photo ID and sign using our Class 3 DSC. No travel to India needed. The signed document is legally valid for Indian government portals and legal proceedings.
How does Aadhaar-based e-Sign work?
An OTP is sent to your Aadhaar-linked mobile number. Once you share that OTP, your document is signed electronically — authenticated against your Aadhaar identity via UIDAI’s infrastructure. It is legally equivalent to a handwritten signature and requires no DSC purchase from your side.
Is the signed document valid in courts and government portals?
Yes. Our Class 3 DSC is issued by a CCA-licensed Certifying Authority. Signatures are fully valid under Section 5 of the IT Act, 2000 — accepted by courts, MCA, GST, Income Tax, EPFO, eTender, GeM, and all major government portals.
Can the signed document be changed after signing?
No. Once digitally signed, the document is cryptographically sealed. Any modification — even a single character — automatically invalidates the signature. This tamper-proof protection is permanent and verifiable by any party instantly.
Is my document kept confidential?
Yes. Documents are received only through encrypted channels (WhatsApp and email), used solely for the signing process, and never shared with any third party.
