Learn the essential do’s and don’ts of maintaining a healthy demat account in India, to avoid fraud and have fulfilling investment experience.

A demat account (short for dematerialised securities account) is the digital equivalent of holding shares, bonds, and other securities. It is set up by depositories like National Securities Depository Limited (NSDL) or Central Depository Services (India) Limited (CDSL), and you get access to one through a Depository Participant (DP). Started in 1996, demat accounts became convenient for traders to complete settlements instantly, compared to physical transfer of securities which could take days and often caused confusion.

However, given the increasing frequency of cyber fraud and hence sharpening of regulatory oversight, it is vital to manage your demat account properly. Below is Mahamoney's guide to ensure your demat account remains healthy, secure, and updated for investment.

10 Best Practices (Do’s)

Choose a reputed broker / DP

Before selecting a Depository Participant to open your demat account, compare their

  1. Cost structures
  2. App usability
  3. Customer support
  4. Fees (see below)
  5. Market reputation 
Read the terms carefully

Before signing up for a demat account, make sure to understand

  1. All fees and charges, especially
    1. Dematerialisation and rematerialisation fees
  2. Transaction and allocation rules
  3. Any Power-of-Attorney (POA) clauses
Keep KYC and contact details updatedImmediately update your address, mobile, email, or bank account changes with the DP to avoid failures or blocked transactions.
Enable alerts, SMS and email notificationsSet up notifications of credits, debits, corporate actions, or modifications, so you can detect unauthorized transactions early.
Use strong and unique passwords
  • Avoid weak passwords.
  • Do not repeat the same password across multiple demat accounts, and/or bank accounts.
  • Enable two-factor authentication wherever supported.
Use Delivery Instruction Slips (DIS) slips carefully
  • Ensure that BO ID/client ID is pre-printed
  • Strike out blank spaces
  • Double-check ISIN and number of shares
  • Don’t leave the DIS blank or partially signed.
Freeze or deactivate your account when not in useIf you are not going to be active for some significant period, use the “freeze account” feature. This prevents unauthorized operations.
Appoint nominees & transmit rightsDeclare nominees with the right share of your investments that you want to go to them. Nominating your heirs to the account helps in seamless inheritance of assets after your death.
Regularly reconcile and review your holdingsCompare DP statements, corporate action records, and your own transaction logs quarterly. This gives you a regular estimate of your wealth, and importantly, taxes due.
Do due diligence before investingThe speed of transaction can be tempting when there is a ‘hot tip’ or aggressive marketing. Always analyze the company's fundamentals, risks (such as debt overhang), valuation, AND your own risk appetite.

10 Common Errors (Don’ts) 

Sharing login credentials, OTP, or DIS slipsDisclosing such sensitive data allows fraudsters to execute trades or transfers without your consent.
Ignoring alerts or statements
  • Don't overlook SMS/email alerts.
  • Unauthorized debits or modifications may go unnoticed, and you may not have timely recourse.
Leaving the account completely inactive
  • Dormant accounts are often targets of hacking or misuse.
  • If not transacting, at least log in and check them periodically.
Filling DIS slips carelessly
  • Mistakes or blanks can be abused; always fill the DIS slip accurately.
  • Avoid overwriting, leaving blanks, mis-entering ISIN 
Granting broad Power-of-Attorney (POA)
  • Some POAs allow brokers/DPs to transact freely.
  • These are liable to misuse, allowing your assets can be sold without your knowledge.
Using cash to pay Demat or brokerage chargesAlways use cheque, bank transfer or in-built online mechanisms.
Unauthorized off-market transfers or over-transferTransferring more shares than you own or doing off-market transfers without negotiating properly may attract regulatory scrutiny.
Opening multiple Demat accounts without control
  • More accounts mean more maintenance and risk
  • You can easily lose track or pay duplicate fees
Overtrading or impulsive transactionsBuying and selling too frequently may lead to losses, high costs and tax burden.
Ignoring regulatory or depository notices & mismatches
  • Respond to depository or SEBI notices as soon as possible.
  • Ignoring mismatch in statements or AIS (Annual Information Statement) can invite penalties.
