If you are sitting on a stack of physical share certificates, you may have already decided that dematerialisation is the way forward. But what if you don’t want to convert everything at once? What if some certificates are tied up in a family dispute, a pending transmission, or simply too old to locate right now?
This is exactly where partial dematerialisation of shares becomes relevant — and it is one of the most common questions Indian investors ask their Depository Participants (DPs) once they start the conversion process.
In this guide, we will walk through what partial dematerialisation of shares actually means, whether SEBI rules allow it, how the process works in practice, and what to watch out for if you decide to convert only some of your holdings rather than the entire lot.
What Does Partial Dematerialisation of Shares Mean?
Partial dematerialisation of shares refers to the practice of converting only a portion of your physical share certificates into electronic (demat) form, while the remainder stays in paper format for the time being. Instead of submitting your entire certificate holding for a company in one go, you choose to convert a subset — say, 200 shares out of a total holding of 500 — and leave the rest untouched until you are ready.
This is different from full dematerialisation, where every certificate you hold for a particular company or folio is submitted together and converted in a single request. Partial dematerialisation of shares gives you the flexibility to convert in stages, which can be useful when certificates are scattered across different lots, purchased at different times, or held jointly with other family members.
Is Partial Dematerialisation of Shares Actually Allowed?
Yes. SEBI and the depositories (NSDL and CDSL) do not require that all certificates for a company be surrendered together. You can submit a Dematerialisation Request Form (DRF) for a specific set of certificates while retaining the rest in physical form. There is no rule that forces an “all or nothing” conversion.
That said, partial dematerialisation of shares does come with a few practical conditions:
- Each certificate you submit must be in the same name(s) and same order of holders as the demat account you are converting into.
- You cannot split a single certificate itself; the certificate is either dematerialised in full or not submitted at all. What you are choosing is which certificates go in, not slicing an individual certificate into pieces.
- If a certificate has been damaged, mutilated, or has an unclear folio number, it may need to be resolved with the Registrar and Transfer Agent (RTA) before it can be included in your partial dematerialisation of shares request.
The Regulatory Backdrop: Why This Question Comes Up So Often
Over the past several years, SEBI has steadily pushed Indian investors away from paper certificates and toward electronic holdings. Transfers of physical shares have been barred since April 2019, meaning a paper certificate can generally no longer be sold or transferred to a third party in physical form — it must first go through the standard dematerialisation process. This single rule change is the reason so many families are now going through their old certificate folders, often for the first time in years, and discovering that their holdings are a mix of clean lots, disputed lots, and lots with mismatched names.
It is in this context that the question of converting only some certificates comes up constantly. Very few investors have a perfectly tidy set of certificates sitting in a drawer. More commonly, there’s a mix: some shares bought directly by the investor, some inherited from a parent, some received as a wedding gift decades ago, and some that came through a bonus issue with a slightly different name spelling. Regulators never intended for investors to be stuck simply because a handful of certificates in a larger pile need extra paperwork — which is exactly why the DRF process was designed to work certificate-by-certificate rather than folio-by-folio.
Documents You’ll Typically Need
Regardless of whether you’re converting one certificate or fifty, the documentation your DP will ask for is largely the same:
- Original physical share certificates for the specific shares you are including in that DRF.
- A filled and signed Dematerialisation Request Form, matching the exact name and signature format on your demat account.
- Self-attested copies of PAN card(s) for all holders named on the certificate.
- Proof of address, if your DP’s records need updating or if there’s a mismatch with the RTA’s records.
- A cancelled cheque or bank proof, to confirm the linked bank account for future dividend payouts.
- An indemnity or affidavit, only if there’s a name mismatch, a missing certificate, or a transmission in progress — this is usually the extra step that applies to the “difficult” batch of certificates rather than the clean ones.
Keeping this list handy before your first visit to the DP’s office can save you a second trip, especially if you’re planning to submit certificates in more than one round.
A Practical Example
Consider an investor who inherited 500 shares of a listed company from a parent. Of these, 300 shares are held under a single name that matches the new demat account cleanly, while 200 shares are jointly held with a sibling who has not yet completed the transmission paperwork on their side.
Rather than waiting for the sibling’s transmission to be finalised — which could take several more months — the investor submits a DRF for the 300 shares that are already in order. Within about three weeks, those shares are sitting safely in the demat account, protected from loss, damage, or the transfer restrictions that apply to physical certificates. The remaining 200 shares stay in physical form until the transmission is complete, at which point a second DRF is filed to bring them across as well.
This kind of staggered approach is common in Indian households where certificates have passed through more than one generation, and it illustrates why the process is built to accommodate partial submissions rather than demanding everything be resolved before any conversion can begin.
How This Affects Your Portfolio Tracking
Once you start converting in stages, your holding for a given company will temporarily be split between two forms: part electronic, part physical. This isn’t a problem for the company’s records — the RTA maintains your total entitlement regardless of form — but it does mean your own tracking needs to be a little more careful.
A few habits help here:
- Keep a single master list of every certificate you own for a company, noting which ones have already been converted and which are still pending.
- Update your list immediately after each DRF is processed, rather than waiting until the end of the year.
- Cross-check against your Consolidated Account Statement (CAS), which shows your demat holdings across depositories, so you can confirm the converted portion has actually landed correctly.
- Set a reminder for any certificates you’ve deliberately held back, so the pending batch doesn’t get forgotten for years.
Why Investors Choose Partial Dematerialisation of Shares Over Full Conversion
There are several genuine reasons why someone might prefer partial dematerialisation of shares instead of converting an entire holding at once.
1. Certificates from Different Sources or Time Periods
Many long-term investors accumulated shares over decades — through IPO allotments, bonus issues, gifts, or inheritance. These certificates often carry different folio numbers, different holder name formats (a maiden name versus a married name, for instance), or different joint-holder combinations. Rather than delaying the entire process while sorting out discrepancies on a few certificates, investors often convert the “clean” certificates first and deal with the problematic ones separately.
2. Ongoing Legal or Succession Matters
If some shares are part of an inheritance that is still being formally transmitted, or are subject to a family settlement, it is common to leave those specific certificates in physical form until the legal position is resolved, while dematerialising everything else. Partial dematerialisation of shares lets you keep moving forward on the portion that is not disputed.
3. Certificates That Are Missing or Damaged
If a few certificates in a larger lot are lost, torn, or illegible, tracking them down or applying for duplicates can take weeks or months. Investors frequently choose this route so the recoverable certificates are digitised immediately, while the problem certificates go through the duplicate-issuance process at their own pace.
4. Testing the Process Before Committing Fully
Some first-time investors are simply cautious. Submitting a small batch as a trial run of partial dematerialisation of shares — and confirming the shares land correctly in the demat account — gives them confidence before they send in the rest of their certificates.
How the Partial Dematerialisation of Shares Process Works
The mechanics of partial dematerialisation of shares are almost identical to a full dematerialisation request; the only difference is the number of certificates you submit at a time.
Step 1: Open or Confirm Your Demat Account You need an active demat account with a registered Depository Participant. The account holder name(s) and order must exactly match the name(s) on the physical certificates you plan to convert.
Step 2: Fill Out the Dematerialisation Request Form (DRF) For each batch you want to convert, you submit a separate DRF listing only the specific certificate numbers and distinctive numbers you wish to dematerialise in that round. This is the form that actually enables a staggered conversion — you are simply choosing to list fewer certificates on it.
Step 3: Attach the Selected Physical Certificates Only the certificates named in that particular DRF are physically submitted. The certificates you are holding back for later stay with you, untouched, until you are ready to file a separate request.
Step 4: DP Verification and Submission to the RTA Your DP checks the DRF against the certificates, defaces them (to prevent duplicate use), and forwards the request to the company’s RTA for verification.
Step 5: RTA Confirmation and Credit to Your Demat Account Once the RTA confirms the details match their records, the shares from that batch are credited electronically to your demat account. This typically takes 15 to 30 days, though timelines vary by RTA and company.
Step 6: Repeat for Remaining Certificates, Whenever You’re Ready There is no deadline forcing you to submit the rest. You can repeat the process for the remaining certificates next month, next year, or whenever the outstanding issues (missing documents, disputes, duplicate applications) are resolved.
Costs Involved in Partial Dematerialisation of Shares
Because each DRF submission is treated as a separate transaction, opting for partial dematerialisation of shares in multiple batches can work out slightly more expensive than one consolidated request, since some DPs charge a flat fee per DRF regardless of how many certificates are listed on it. It is worth asking your DP for their exact fee structure before deciding how to split your batches — grouping certificates sensibly (for example, by folio or by holder combination) can help you avoid unnecessary DRF submissions.
Common Mistakes Investors Make with Partial Dematerialisation of Shares
Mixing certificates with different name orders in one DRF. If certificate A lists “Ramesh Kumar and Sunita Kumar” and certificate B lists “Sunita Kumar and Ramesh Kumar,” these cannot go into the same DRF even though they belong to the same folio family. This is a frequent reason DRFs for partial dematerialisation of shares get rejected or returned.
Forgetting to keep a record of what has and hasn’t been converted. When you split your holdings across multiple DRFs over time, it is easy to lose track of which certificates have already been converted and which are still sitting in physical form. Maintain a simple spreadsheet noting certificate numbers, distinctive number ranges, DRF submission dates, and status.
Assuming corporate benefits will keep flowing to physical shares. SEBI has progressively restricted transactions on physical shares over recent years, including transfers. Dividends, bonus issues, and rights entitlements can still reach a physical shareholder in many cases, but the safer long-term approach is to complete the conversion on the remaining certificates sooner rather than later, since regulatory restrictions on physical holdings have only tightened over time.
Not verifying the folio and PAN linkage beforehand. Before you file any DRF, confirm that your PAN, address, and bank details are updated with the RTA. Mismatches here are one of the most common causes of delay, whether you are converting everything at once or doing it in parts.

Frequently Asked Questions on Partial Dematerialisation of Shares
Can I dematerialise just one certificate out of ten I own in the same company? Yes. Partial dematerialisation of shares allows you to submit as few as one certificate, as long as the holder name and order match your demat account.
Will my remaining physical certificates still be valid after converting only some of them? Yes, they remain legally valid physical certificates. However, keep in mind that SEBI has tightened rules around transferring physical shares, so you should still plan to dematerialise them eventually.
Does partial dematerialisation of shares affect my shareholder rights, like dividends or voting? No. Whether your shares are in physical or demat form (or split between the two), your entitlement to dividends, bonus shares, and voting rights as recorded with the RTA remains intact, provided your folio details are up to date.
How long does each round of partial dematerialisation of shares take? Each DRF submission typically takes 15 to 30 days from submission to credit in your demat account, similar to a full dematerialisation request, since the RTA processes each batch independently.
Is there a limit to how many times I can do partial dematerialisation of shares for the same company? There is no regulatory cap on the number of DRFs you can file over time. However, doing it in smaller batches means more paperwork and, potentially, more DP charges, so it makes sense to consolidate certificates into as few batches as practically possible.
Should You Choose Partial Dematerialisation of Shares?
If your certificates are in clean, matching condition, filing one consolidated dematerialisation request is usually simpler and cheaper. But partial dematerialisation of shares is the right call when:
- Some certificates are tied up in inheritance, transmission, or a family settlement that hasn’t concluded yet.
- A few certificates are missing, damaged, or need a duplicate to be issued.
- Your certificates carry inconsistent name orders or joint-holder combinations that need separate handling.
- You simply want to convert a portion first, confirm everything works, and process the rest afterward.
For readers who are still deciding between converting everything now versus doing partial dematerialisation of shares in stages, it often helps to first understand the full dematerialisation process for physical shares, which covers the DRF process, documentation, and timelines in more detail. That guide is a useful starting point before you decide how to split your own certificate batches.
A Note for NRI and Second-Generation Holders
If you are an NRI managing shares inherited from a parent or grandparent in India, staggered conversion is often the only realistic option. Between arranging notarised documents from abroad, coordinating with siblings who may be co-holders, and dealing with certificates that are decades old, it is rarely practical to gather everything for a single submission.
In these cases, it makes sense to convert whatever documentation is complete first, protecting that portion of the holding immediately, while the remaining paperwork is chased down over subsequent visits or through a power of attorney held by a trusted representative in India.
This staged approach also reduces the risk of losing an entire inheritance to a single missing document, since each certificate’s fate is handled independently rather than being tied to the slowest-moving piece of paper in the file.
Final Thoughts
Partial dematerialisation of shares is not a workaround or an exception — it is a legitimate, SEBI-compliant path that many Indian investors use when their physical share certificates are not in a uniform, ready-to-convert state. Whether you are dealing with an inherited folio, a mismatched joint-holding, or simply a missing certificate from years ago, you do not need to wait until every single certificate is sorted out before you begin. You can start with what is ready today and handle the rest as those issues resolve.
