A wrong Demat transaction can mean an unexpected debit, incorrect credit, unauthorised transfer, wrong quantity, or another transaction that does not match your records. Such an entry should not be ignored, especially when securities have been removed from or transferred out of your Demat account.
The first step is usually to contact your broker or Depository Participant (DP) and ask them to investigate the transaction. If the issue is not resolved, you can escalate the complaint to the relevant depository, such as CDSL or NSDL, and then use SEBI’s SCORES platform where applicable.
SEBI’s current SCORES process requires investors to first approach the concerned regulated entity for grievance redressal before escalating the matter through SCORES.
What Is a Wrong Demat Transaction?

A wrong Demat transaction is a securities-account entry that is incorrect, unexpected or not authorised by you.
Examples include:
- Shares debited even though you did not sell them
- Shares transferred to an unknown Demat account
- Incorrect number of shares credited
- Shares credited to the wrong security or ISIN
- An unexpected pledge or other securities movement
- A transaction appearing in your statement that you cannot identify
- A legitimate transaction recorded with incorrect details
However, an unexpected entry is not necessarily fraudulent. It could result from a bonus issue, stock split, merger, rights issue, IPO allotment, transmission, transfer or another corporate action.
Therefore, first identify what the transaction represents.
Common Types of Wrong Demat Transactions
| Problem | Example |
| Unauthorised debit | 100 shares removed without your instruction |
| Incorrect credit | 500 shares credited instead of 50 |
| Unknown transfer | Securities transferred to another account |
| Wrong security | Incorrect ISIN or security reflected |
| Duplicate entry | Same transaction appears twice |
| Incorrect quantity | Number of shares does not match your records |
| Unexplained transaction | Entry appears without an identifiable reason |
Step 1: Check Your Demat Transaction Statement
Before filing a complaint, download your latest Demat transaction statement.
Check:
- Transaction date
- Security name
- ISIN
- Quantity
- Debit or credit
- Transaction description
- Reference number, if available
- Opening and closing balance
Also compare the entry with your previous statement.
This helps establish exactly what went wrong and gives you evidence to share with your broker or DP.
Step 2: Check Your Trading Account
If the transaction relates to a purchase or sale, check your broker’s:
- Order history
- Trade book
- Contract note
- Ledger
- Position or holdings report
- Corporate-action records
For example, suppose 100 shares were debited from your Demat account.
If your trading account shows a sale of 100 shares on the same date, the debit may be related to that trade. If there is no corresponding order or trade, you should ask your broker and DP to investigate.
Step 3: Check Whether It Was a Corporate Action
Some Demat transactions occur without a normal buy or sell order.
Check whether the company recently carried out:
- Bonus issue
- Stock split
- Rights issue
- Merger
- Amalgamation
- Consolidation
- Other corporate action
This is particularly important when you see an unexpected credit.
For example, receiving additional shares without buying them could be the result of a bonus issue or stock split rather than an incorrect transaction.
Step 4: Contact Your Broker or DP
Your Depository Participant (DP) is generally the first point of contact for a Demat-account grievance.
If the issue relates to a trade, order or broker-side activity, contact the broker as well.
Give them a clear description of the problem and provide supporting records.
Information to Include
| Information | Why It Is Useful |
| Demat account/BO ID | Identifies the account |
| PAN | Identifies the investor |
| Security name | Identifies the affected security |
| ISIN | Precisely identifies the security |
| Transaction date | Helps locate the entry |
| Quantity | Shows the disputed amount |
| Transaction/reference number | Helps trace the transaction |
| Statement/screenshot | Provides evidence |
| Expected correction | Clearly explains what you want investigated |
Avoid sending your Demat password, TPIN, OTP or trading password in a complaint.
Step 5: Ask for a Written Explanation
Do not rely only on a phone conversation when the issue involves an incorrect or unauthorised securities transaction.
Ask the broker or DP to provide:
- Reason for the transaction
- Transaction/instruction details
- Date and time, where available
- Relevant reference number
- Details of the account or process involved
- Corrective action proposed
Keep the complaint number or ticket ID.
This creates a record that you can use if escalation becomes necessary.
What If the Broker Says the Transaction Is Correct?
Ask the broker to explain which order, instruction or event authorised the transaction.
For a sale, compare the Demat debit with:
- Order ID
- Trade ID
- Contract note
- Execution time
- Quantity
- Security/ISIN
If the transaction was caused by a corporate action, ask for the relevant corporate-action details.
If you still disagree with the explanation, take the matter to the appropriate DP or depository grievance mechanism.
Step 6: Escalate to CDSL or NSDL
Your next step depends on which depository holds your Demat account.
If Your Account Is With CDSL
If the complaint concerning your DP is not resolved, you can use CDSL’s investor grievance mechanism.
CDSL’s current complaint process provides for investors to approach the concerned intermediary/DP first and then use the depository’s grievance mechanism. CDSL also maintains current complaint and redressal information for complaints against DPs.
You should provide the relevant account information and supporting documents when submitting the complaint.
If Your Account Is With NSDL
For an NSDL Demat account, the investor can first approach the concerned DP. If the grievance is not resolved, it can be escalated to NSDL through its available grievance mechanism.
NSDL’s Investor Charter describes a grievance process involving the DP, the depository and further grievance mechanisms where required.
Step 7: Use SEBI SCORES if Required
If the issue concerns a SEBI-regulated entity and remains unresolved after approaching the concerned entity, you can lodge a complaint through SCORES, SEBI’s online grievance redressal platform.
SCORES allows investors to select the relevant entity and complaint category, track the complaint and, where applicable, seek review of the response.
Importantly, the current SCORES website states that investors should first take up their grievance with the concerned entity.
Also note that SEBI says SCORES is a facilitation platform for grievance redressal; it is not a replacement for every other dispute-resolution mechanism.
How to File a Strong Demat Complaint on SCORES
A complaint should be specific and supported by documents.
Include:
- Your Demat/BO account details
- Name of the broker or DP
- Transaction date
- Security name and ISIN
- Number of shares involved
- Description of the disputed transaction
- Your communication with the broker/DP
- Complaint or ticket number
- Supporting statements and screenshots
- The resolution you are seeking
SEBI’s SCORES FAQ notes that incomplete or unspecified complaints and complaints without supporting documents may not be considered.
Example of a Wrong Demat Transaction
Suppose you had 500 shares of ABC Ltd.
You check your Demat statement and discover:
Debit: 200 shares
You did not sell any ABC Ltd. shares.
You should:
- Check the broker’s order and trade history
- Check whether the shares were transferred
- Check whether there was a pledge or other account activity
- Verify the ISIN and transaction description
- Contact your broker/DP immediately
- Ask for the transaction reference and instruction details
- Keep the complaint reference number
- Escalate to CDSL/NSDL if the DP does not resolve it
- Use SCORES where applicable if the regulated-entity grievance remains unresolved
The important point is to create a documented trail rather than simply making a verbal complaint.
What Documents Should You Keep?
Keep copies of all relevant records, including:
- Demat transaction statement
- Holding statement
- Broker trade report
- Contract note
- Order history
- Screenshots
- Email/SMS alerts
- Corporate-action documents
- Complaint emails
- Ticket/reference numbers
- Replies from the broker or DP
- CDSL/NSDL complaint records
- SCORES complaint details, if used
Do not delete the original records after submitting a complaint.
What If Shares Were Transferred Without Your Permission?
An unauthorised transfer is more serious than a simple statement error.
Immediately:
- Contact your DP.
- Ask them to investigate the transfer.
- Ask for the transaction/instruction details.
- Secure your trading and Demat accounts.
- Change relevant passwords if you suspect account compromise.
- Preserve all transaction evidence.
- Escalate through the depository grievance process if necessary.
If you suspect fraud or identity misuse, you may also consider reporting the matter to the appropriate law-enforcement or cybercrime authority in addition to the securities-market grievance process.
How Long Does a Demat Complaint Take?
The time can vary depending on the nature of the complaint, the intermediary involved and the escalation stage.
For example, NSDL’s Investor Charter states that complaints lodged directly with the depository are to be resolved within the period specified in its grievance mechanism, currently stated as 30 days in the charter.
CDSL separately maintains grievance records and monitoring of complaints against DPs, including reporting of grievances pending beyond specified periods.
Therefore, investors should keep the complaint reference and monitor its status rather than assuming that the issue has been resolved.
Broker vs DP vs Depository: Whom Should You Contact?
| Situation | First Contact |
| Wrong trade/order | Broker |
| Demat balance problem | DP |
| Unauthorised securities debit | DP and broker, as applicable |
| Securities transfer issue | DP |
| Corporate-action credit/debit | DP/company or relevant intermediary |
| DP grievance unresolved | CDSL or NSDL |
| Regulated-entity complaint still unresolved | SEBI SCORES, where applicable |
The broker and DP can sometimes be part of the same business, but their functions are not identical. The broker handles trading activities, while the DP provides Demat/depository services.
Common Mistakes to Avoid
Do Not Wait for the Next Monthly Statement
If you notice a suspicious debit or transfer, report it promptly.
Do Not Delete Evidence
Save statements, screenshots, emails and transaction alerts.
Do Not Send OTPs or Passwords
A genuine complaint does not require you to disclose your login password, OTP or similar authentication credentials.
Do Not File an Unclear Complaint
State exactly what transaction is disputed and what you want the intermediary to investigate.
Do Not Skip the Initial Complaint
For SCORES, SEBI’s current process says investors should first approach the concerned entity.
Frequently Asked Questions
Can I complain directly to CDSL or NSDL about a wrong Demat transaction?
You should generally first approach your DP or concerned intermediary. If the grievance is not resolved, you can use the relevant depository’s complaint mechanism.
Can I report an unauthorised share debit to my broker?
Yes. If the debit relates to a trade or broker-side activity, contact the broker immediately. You should also contact the DP because the issue concerns your Demat account.
What if my broker does not resolve my complaint?
You can escalate the matter through the applicable DP/depository grievance mechanism and, for complaints involving SEBI-regulated entities, use SCORES after first approaching the concerned entity.
What proof do I need for a Demat complaint?
Your transaction statement, account details, transaction date, ISIN, quantity, screenshots, broker records and previous communication can help establish the issue.
Can I complain on SCORES by email?
The current SCORES website states that grievances sent by email to SEBI email addresses are not entertained through that route; complaints should be lodged through the SCORES portal.
Conclusion
If you find a wrong Demat transaction, first identify the exact entry and check your broker records, corporate actions and previous statements. Then raise a written complaint with your broker or Depository Participant, keeping the complaint reference and all supporting documents.
If the matter is not resolved, you can escalate it to CDSL or NSDL, depending on your depository, and use SEBI SCORES for eligible grievances involving SEBI-regulated entities. A clear complaint supported by transaction statements and other records makes it easier for the concerned organisation to investigate the issue.
