How to convert physical share certificates to demat

If you’ve inherited shares from a parent or grandparent, or stumbled across old paper certificates while clearing out a cupboard, you’re not alone. Millions of Indians still hold physical share certificates — old Infosys shares from the 90s, Reliance certificates that have been sitting in a drawer for decades. The good news is that converting them to demat form is straightforward. The bad news is that most people don’t know where to start, so those shares just sit there, quietly doing nothing.

Here’s exactly what you need to do.

First, Understand Why This Actually Matters

Physical shares are nearly impossible to sell. SEBI — India’s market regulator — mandated back in 2019 that all share transfers must happen in demat form only. So if your father left you 200 shares of HDFC Bank in paper form, you can’t just walk into a broker and sell them. You need to dematerialise them first.

Beyond selling, there’s also the question of corporate benefits. Dividends, bonus shares, and stock splits all get credited to your demat account. If your shares are sitting in physical form, there’s a real risk these benefits don’t reach you cleanly — or at all.

If the certificates were never claimed in the first place, start instead with unclaimed shares and dividends held by IEPF — the shares have to come back to you before they can be dematerialised.

What You Need Before You Start

You need two things in place before anything else: a demat account and a DP (Depository Participant).

A DP is just the official name for the institution that holds your shares in electronic form on your behalf — think of it like a bank, but for shares instead of money. Zerodha, Groww, HDFC Securities, and SBI Securities are all DPs. If you already have a trading account with any of these, you almost certainly already have a demat account attached to it.

Also make sure you have your PAN card, Aadhaar, and — critically — the original physical share certificates. If the certificates are in someone else’s name (a deceased relative, for example), there’s a separate transmission process, which is worth a separate article entirely.

The Actual Process, Step by Step

Step 1: Fill out a Dematerialisation Request Form (DRF). This form is available from your DP — download it from their website or pick it up at their branch. Zerodha and Groww both have downloadable PDFs on their support pages. Fill in your demat account number, the company name, the number of shares, and certificate details.

Step 2: Deface the physical certificates. Write “Surrendered for Dematerialisation” across the face of each certificate before submitting. This sounds dramatic, but it’s mandatory — it stops the certificates from being used again.

Step 3: Submit the DRF and certificates to your DP. You’ll submit the defaced certificates along with the DRF form. If you’re in Bangalore and your DP is HDFC Securities, you’d courier or walk them into your nearest branch. Keep photocopies of everything before you hand anything over.

Step 4: Wait. Your DP forwards the request to the company’s Registrar and Transfer Agent (RTA). The RTA — companies like KFin Technologies or CAMS handle this for most listed Indian companies — verifies everything and then instructs the depository (either NSDL or CDSL) to credit the shares to your account.

The typical turnaround is 15 to 30 days. It can stretch longer for older certificates or companies with complex records.

What It Costs

The charges are small but worth knowing. Most DPs charge a dematerialisation fee of around ₹3 to ₹5 per certificate, plus courier charges if applicable. So if you’re converting 5 old certificates, you’re looking at ₹15–₹25 in fees — essentially nothing relative to the value of shares you’re unlocking.

Some DPs charge a one-time account opening fee (Zerodha charges ₹200 for demat account opening). Annual maintenance charges — the yearly fee to keep your demat account active — typically run ₹300 to ₹500 per year depending on the broker.

The One Thing That Trips People Up

The most common problem is a name mismatch. If your certificate says “Ramesh Kumar” but your PAN says “Ramesh K. Kumar”, the RTA can reject the request. Before submitting anything, check that the name on the certificate matches exactly what’s on your PAN and demat account. If it doesn’t match, you’ll need to submit a name correction request first — your DP can guide you through this, and it typically needs an affidavit or gazette notification.

This single issue causes the majority of delays. Catch it before you submit and you’ll save yourself weeks of back-and-forth.

Frequently Asked Questions

Can I convert shares of any company, or only listed ones?

Only shares of companies listed on BSE or NSE can be dematerialised through the standard process. If the company is delisted or wound up, the process is different and considerably more complicated.

What happens if I’ve lost the physical certificate?

You’ll need to apply for a duplicate certificate from the company’s RTA before you can dematerialise. This involves submitting an FIR, an indemnity bond, and a surety form. It adds time and paperwork but is doable.

How do I check if my demat account is with NSDL or CDSL?

Your demat account number tells you. NSDL accounts start with IN followed by 14 digits. CDSL accounts are 16 digits with no prefix. You can also check via your broker’s app under account details.

Will I have to pay tax when I convert shares to demat?

No. Conversion itself isn’t a taxable event. Tax only applies when you actually sell the shares. The original purchase date of the physical shares is what counts for calculating your holding period and capital gains.

My grandfather’s shares are in his name and he’s passed away. Can I still convert them?

Yes, but this is a transmission case, not a standard dematerialisation. You’ll need a death certificate, legal heir certificate or will, and a transmission request form. The RTA and your DP will walk you through the specific documents needed — it varies slightly by company.
