Under Section 63 of the Bharatiya Sakshya Adhiniyam (BSA), 2023 — which replaced the Indian Evidence Act on 1 July 2024 — all electronic records including WhatsApp chats are admissible as evidence only if accompanied by a mandatory Section 63(4)(c) certificate.

The Supreme Court in _Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2020) 7 SCC 1_ made this crystal clear:

"The applicability of procedural requirement under Section 65B(4) of the IEA of furnishing certificate is to be applied only when such electronic evidence is produced by a person who is in a position to produce such certificate."

This principle carries directly into Section 63 BSA. Without the certificate, electronic evidence is inadmissible regardless of how authentic it appears.

What the Certificate Must Contain (Section 63(4)(c) + Schedule):

Element Requirement Why It Matters
Part A Signed by device owner/custodian Confirms lawful possession and proper operation
Part B Signed by expert Verifies technical integrity and hash value
Device Details Make, model, serial number, IMEI Links evidence to specific device
SHA-256 Hash Mandatory digital fingerprint Proves file hasn't been tampered with
Description How the record was produced Establishes chain of custody

Step-by-Step: The Complete Submission Process

Step 1 — Export the Chat from WhatsApp (The Most Critical Step)

Why this matters: The export is your primary evidence. Everything else depends on this file being untampered.

Android:

  1. Open WhatsApp → Open the specific chat
  2. Tap ⋮ (three dots) → More → Export Chat
  3. Select "Without Media" (media complicates certification)
  4. Save the `.txt` file to a secure location
  5. Do not open, edit, or rename the file

iPhone:

  1. Open WhatsApp → Open the chat → Tap contact name at top
  2. Scroll down → Export Chat → "Without Media"
  3. Save the `.zip` file via Mail or Files app
  4. Do not extract or modify the file
⚠️ CRITICAL WARNING: After export, even a single character change will alter the SHA-256 hash and invalidate your certificate. Treat the exported file as sacred.

Step 2 — Generate the Section 63 BSA Certificate and Section 63 BSA PDF

Option A: Using Chat2Evidence (Recommended)

  1. Visit chat2evidence.in
  2. Upload your `.txt` or `.zip` file
  3. Enter:
  1. The tool automatically:

Option B: Manual Process (Not Recommended)

💡 Time Comparison: Chat2Evidence = 3 minutes | Manual = 3-4 hours | Lawyer-prepared = ₹5,000-15,000

Step 3 — Sign the Certificate and Prepare Supporting Documents

Print the PDF and:

  1. Sign Page 1 (certificate page) in the signature block
  2. Add date, time, and place
  3. Get Part B signed by an expert (IT professional, cyber forensics expert)

Prepare Affidavit (if required by your court):


I, [Your Name], son/daughter of [Father's Name], aged [Age], residing at 
[Address], do hereby solemnly affirm and declare as follows:

1. That I am the plaintiff/defendant/complainant in the above-mentioned case.
2. That the WhatsApp conversations between myself and [Opposing Party] 
   are annexed hereto as Exhibit [A/B/C].
3. That the said electronic record was exported from my [Device Model] 
   on [Date] and has not been altered since.
4. That the Section 63(4)(c) certificate accompanying the record 
   is true and correct to the best of my knowledge.
Note: Some courts (especially family courts in Delhi and Bombay) require the affidavit on ₹10 or ₹20 stamp paper. Confirm with your advocate.

Step 4 — Number as Exhibit and File Through Advocate

Exhibit Marking Convention:

Your advocate will:

  1. Mark the PDF with exhibit number
  2. List it in the documents list (Index of Documents)
  3. File it with the court clerk
  4. Serve a copy on the opposite party
Keep the original `.txt` or `.zip` file safe. The court may ask for it during cross-examination or if the opposite party challenges the hash value.

Step 5 — Reference in Your Written Statement or Affidavit

Sample reference for civil case:

"The WhatsApp conversations between the Plaintiff and Defendant dated [Date Range] are annexed hereto and marked as Exhibit A, certified under Section 63(4)(c) of the Bharatiya Sakshya Adhiniyam, 2023. The complete chat timeline, SHA-256 hash value, and certificate are contained in the annexure."

Sample reference for criminal case:

"The complainant submits the WhatsApp chat export (Exhibit P-1) between the accused and the complainant, certified under Section 63(4)(c) BSA 2023, with SHA-256 hash value [Hash] to establish [purpose]."

Court-Specific Procedures

Civil Court Procedure

Stage What Happens Your Action
Filing of Suit Plaintiff files plaint + documents Attach WhatsApp evidence as Annexure
Written Statement Defendant responds Reference exhibit in WS
Admission/Denial Court asks parties to admit/deny documents Be ready to explain certificate
Evidence Stage Witnesses examined You may be examined on the chat
Arguments Final submissions Advocate argues admissibility

Key Point: In civil courts, electronic evidence is typically filed with the initial pleadings or during the evidence stage. Late filing requires court permission.

Criminal Court Procedure

Stage What Happens Your Action
FIR/Complaint Police register case or private complaint filed Preserve evidence immediately
Chargesheet Police file chargesheet with evidence Certificate must accompany chargesheet
Trial Prosecution evidence led Witness (you) examined on the chat
Defense Evidence Accused may produce counter-evidence Be ready for cross-examination

Key Point: In criminal cases, the Section 63 certificate must accompany the chargesheet or complaint. Filing it later is subject to court discretion and often challenged.

Family Court Procedure

Stage What Happens Your Action
Petition Filing File petition for divorce/maintenance/custody Attach WhatsApp evidence
Counseling Mandatory counseling session Evidence not discussed
Evidence Stage Parties lead evidence WhatsApp chat examined
Judgment Court decides Evidence weight assessed

Key Point: Family courts are more lenient with procedural requirements but stricter on privacy. Chats obtained by snooping on a spouse's phone may be challenged on privacy grounds.

Consumer Forum Procedure

Stage What Happens Your Action
Complaint Filing File consumer complaint Attach WhatsApp evidence of deficiency
Notice to Opposite Party Forum issues notice Opposite party may challenge evidence
Evidence Stage Simple procedure — affidavits accepted File affidavit with exhibit

Key Point: Consumer forums follow summary procedure. Self-certified evidence is often accepted if properly formatted.

Common Mistakes That Get Evidence Rejected

Mistake 1: Submitting Screenshots Only

What happens: Court rejects outright.

Why: Screenshots can be edited, have no hash value, and no certificate can properly cover them.

Fix: Always export the chat as `.txt` file.

Mistake 2: Missing Section 63 Certificate

What happens: Opposing counsel objects, judge excludes evidence.

Why: Certificate is mandatory per Arjun Panditrao Khotkar and Section 63(4).

Fix: Generate certificate using Chat2Evidence or lawyer.

Mistake 3: No SHA-256 Hash

What happens: Defense challenges data integrity. Judge gives less weight or excludes.

Why: Hash is mandatory under Section 63 and 2026 SC ruling.

Fix: Always include SHA-256 hash in certificate.

Mistake 4: Editing the Exported File

What happens: Hash mismatch detected. Certificate invalid. Possible perjury charges.

Why: Even one character change alters the hash completely.

Fix: Never edit the exported file. Not even renaming.

Mistake 5: Wrong Device Details

What happens: Certificate invalidated. Evidence excluded.

Why: Device model/IMEI in certificate must match actual device.

Fix: Double-check device details before generating certificate.

Mistake 6: Late Filing

What happens: Court may refuse to admit. Defense objects.

Why: Section 63 says "at each instance" the record is submitted.

Fix: File at admissibility stage. If late, apply with sufficient cause.

Mistake 7: Only Part A Signed (Missing Part B)

What happens: Certificate incomplete. Evidence rejected.

Why: Section 63(4)(c) requires BOTH Part A and Part B.

Fix: Get Part B signed by any IT professional or cyber expert.

Mistake 8: Challenging Without Original Device

What happens: If opposite party challenges and you can't produce device, evidence weakened.

Why: Court may want to verify hash against original.

Fix: Preserve the original phone. Don't factory reset.

Cross-Examination: What to Expect

If you're the witness producing WhatsApp evidence, expect these questions:

From Opposing Counsel:

Question Purpose Your Preparation
"Did you edit this chat?" Challenge authenticity Know the hash value. Explain it proves no edits.
"Who signed Part B?" Challenge expert qualification Have expert's CV ready.
"Where is the original phone?" Demand primary evidence Keep phone safe and accessible.
"Can you explain SHA-256?" Test technical knowledge Understand it's a digital fingerprint.
"Were these messages obtained illegally?" Privacy challenge Explain lawful possession of device.
"Is this the complete chat or selected?" Allegation of cherry-picking Export full chat, not selected messages.

Tips for Cross-Examination:

  1. Know your hash value — Be able to explain what it is and why it matters
  2. Bring the original device — Court may ask to see it
  3. Be consistent — Your affidavit, certificate, and oral testimony must match
  4. Don't speculate — If you don't know, say so
  5. Stay calm — Opposing counsel will try to rattle you

State-Wise Variations in Practice

While Section 63 BSA is uniform nationwide, practice varies by state:

State/UT Notable Practice
Delhi Strict on format. Stamp paper affidavit often required. Family courts very particular about privacy.
Maharashtra (Bombay) Moderate. Accepts self-certification for Part A. IT professionals accepted as Part B experts.
Tamil Nadu (Madras) Forensic labs often involved for Part B. Police cyber cell certificates carry weight.
Karnataka Progressive. Early adopter of digital filing. E-courts accept digital exhibits.
Uttar Pradesh Traditional. Physical filing preferred. Stamp paper mandatory for affidavits.
Andhra Pradesh Self-certification accepted (2025 HC ruling). Litigant can sign Part A for own device.
Gujarat Moderate. Emphasis on complete chat export. Partial exports often challenged.
Rajasthan Traditional. Physical copies with color prints preferred.
