Demat Account Debit Without Authorisation: Depository, Broker and SEBI Complaint Workflow
By Ravi Sisodia · Reviewed by CA Divyanshu Sengar · Updated 5 October 2026
India-first finance and compliance workflow with primary-source anchors.
2-minute summary
- An unexplained demat debit should be treated first as a securities-ledger incident, not as a generic “broker complaint”. Capture the depository statement, transaction type, ISIN, quantity, execution/settlement date, DP ID/client ID and any DIS/eDIS/TPIN authorisation trail before more entries overwrite the timeline.
- Escalation should normally start with the depository participant or broker, depending on who initiated the transaction, and then move through the exchange/depository grievance mechanism and SCORES where unresolved. SCORES 2.0 currently uses a 21-calendar-day action-taken-report stage, followed by investor review windows; ODR may be relevant where the matter becomes a monetary dispute.
- Do not assume every unexpected debit is an unauthorised market sale. It may be a pledge invocation, off-market transfer, corporate action, margin-related movement or broker/depository correction. The complaint should identify the exact transaction code and the authority that allegedly supports it.
Current position
Control and decision map
| # | Control / decision step |
|---|---|
| 1 | Download the transaction and holding statements from the depository/DP source, not only the broker app screenshot. |
| 2 | Identify whether the debit was exchange-settlement, off-market, pledge-related or another transaction type. |
| 3 | Ask for the underlying authorisation record, including eDIS/TPIN or instruction details where relevant. |
| 4 | Raise a written complaint with the DP/broker and record complaint/reference numbers. |
| 5 | Escalate unresolved service failure through the relevant depository/exchange and SCORES 2.0. |
| 6 | For a monetary or contractual dispute, assess whether the ODR route is available instead of repeatedly filing the same grievance. |
Evidence pack
- CDSL/NSDL or DP transaction statement
- Contract notes and broker ledger if a trade is alleged
- eDIS/TPIN/DIS/pledge authorisation evidence
- Complaint IDs, emails and call records
- SCORES/ODR filings and action-taken responses
Worked example
An investor sees 500 shares of a listed company debited but finds no matching sell contract note. The first step is to obtain the depository transaction description and ask the DP for the instruction trail. If the debit was an off-market transfer and the investor denies authorisation, the complaint should say exactly that and attach the DP evidence rather than merely alleging “broker fraud”.
Common mistakes
- Relying only on a broker-app holdings screen.
- Deleting SMS/email alerts that may show the authorisation trail.
- Filing on SCORES without first identifying the responsible regulated entity.
- Calling every debit a sale without checking transaction type.
Frequently asked questions
Should I complain to the broker or depository participant?
Start with the entity responsible for the transaction path; sometimes the same group performs both roles.
Can SCORES reverse the debit itself?
SCORES is a grievance-resolution framework; transaction restoration or compensation depends on facts and the responsible entity/process.
When is ODR relevant?
When an eligible dispute remains after the prescribed grievance path and requires conciliation/arbitration rather than only service correction.
