Digital Evidence Certificate in Kolkata — BSA §63(4)(c).
A digital evidence certificate under Section 63(4)(c) of the Bharatiya Sakshya Adhiniyam, 2023 (the successor to Section 65B of the Indian Evidence Act, 1872, in force from 1 July 2024) is obtained in Kolkata through DRMLAW LLP's forensic certification portal, with walk-in intake at two Kolkata offices. Each item of evidence is hashed with SHA-256, MD5 and SHA-512, independently re-verified by a second examiner, and issued as a signed Part A statement of contents + Part B computer-output certificate — chain-of-custody aligned to the Supreme Court's ruling in Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal.
The full pricing, process and BSA 2023 mechanics live on the main forensics page. This page covers what's specific to operating out of Kolkata: which local courts and police cyber cells the certificate is tendered before, which case types bring most clients here, and how walk-in intake works at our two Kolkata offices.

FAQ
What is a digital evidence certificate under Section 63(4)(c) of the BSA?
It is the statutory successor to a Section 65B certificate under the Indian Evidence Act, 1872 (in force from 1 July 2024) — a Part A statement of contents plus a Part B computer-output certificate that supports the admissibility of electronic evidence in an Indian court.
Who can issue a digital evidence certificate in Kolkata?
DRMLAW LLP issues these certificates from its two Kolkata offices — 7A, K.S. Roy Road (near the Calcutta High Court) and BJ 19, Sector II, Salt Lake — through a dual-declarant process combining a forensic examiner and the device/cloud custodian, with certificates signed by advocates enrolled with the Bar Council of West Bengal.
Is a BSA Section 63(4)(c) certificate from DRMLAW accepted before the Calcutta High Court?
Yes. Section 63(4)(c) of the Bharatiya Sakshya Adhiniyam, 2023 is a pan-India evidentiary provision, not a Kolkata-specific one — but because DRMLAW's forensic examiners and signing advocates are based at its Kolkata offices, the firm can usually depose or clarify the certificate in person before the Calcutta High Court, City Sessions Court or Bidhannagar District Court without the delay of an out-of-station witness.
How long does certification take?
The pipeline is submit → hash & verify → review → download certificate → physical delivery. An exact turnaround depends on evidence volume and is confirmed via the in-portal fee calculator before work begins; a formal fixed-fee quotation follows once the evidence is actually reviewed.
Can I walk in to either Kolkata office, or does everything go through the online portal?
Both. Walk in to K.S. Roy Road (near the High Court/Dalhousie legal district) or Salt Lake Sector II with a device or drive, or upload through the online case portal from anywhere in West Bengal or outside it — the hashing and certification pipeline is identical either way.
