The genius of the Depositories Act, 1996 lies in a quiet legal fiction: a share that you continue to own in every economic sense is, on the issuer's register, owned by someone else entirely. That someone is the depository, and the bundle of statutory functions it performs to make this fiction work, holding securities in dematerialised form, recording you as beneficial owner, registering transfers by book entry, and returning the security to paper if you ask, is what the Act and SEBI's bye-laws describe as the services of a depository. Sections 5 to 9 of the Act form the operative core of these services, and around them the Supreme Court has built a body of doctrine, most recently in PTC India Financial Services Ltd. v. Venkateswarlu Kari (2022), that tells us exactly how far the depository's name on a register can, and cannot, travel. This chapter unpacks each service, the rights it creates, and the litigation it has generated.
What the Act means by "services of a depository"
The Depositories Act does not contain a single section captioned "services" that exhaustively lists everything a depository does. Instead, the expression is functional. Section 5, titled Services of depository, is the gateway provision: it says that any person, through a participant, may enter into an agreement, in such form as may be specified by the bye-laws, with any depository for availing its services. Everything that follows, surrender and dematerialisation under Section 6, registration of transfer under Section 7, the option to hold in demat form under Section 8, fungibility under Section 9, pledge under Section 12, and rematerialisation under Section 14, is the content of those services.
Two structural points must be grasped at the outset. First, the investor never deals with the depository directly; the relationship is intermediated by a participant (a depository participant, or DP), the depository's agent under Section 4. This three-tier architecture, issuer, depository, participant, with the investor at the outer edge, is the spine of the whole system, and it is examined in detail in our note on the agreement between depository and participant. Second, the depository's role is custodial and ministerial, not proprietary: it holds and records, it does not own in any beneficial sense. The Act keeps these two ownerships, registered and beneficial, rigorously apart, a separation the Supreme Court has repeatedly insisted upon.
For a grounding in the scheme as a whole, including the immobilisation-versus-dematerialisation debate that the Indian model resolved in favour of pure demat, see the introduction, object and scheme of the Act. The present chapter assumes that backdrop and concentrates on the operative services.
Section 5: the agreement to avail services
Section 5 is deceptively short but jurisdictionally important. It provides that any person, through a participant, may enter into an agreement, in such form as may be specified by the bye-laws, with any depository for availing its services. Three features deserve emphasis. The phrase through a participant makes the DP the compulsory conduit; an investor cannot contract with NSDL or CDSL over the counter. The phrase in such form as may be specified by the bye-laws subordinates the contract to the depository's bye-laws framed under Section 26 and approved by SEBI, so the "agreement" is largely a standard-form instrument rather than a freely negotiated one. And the words availing its services tie the contract back to the statutory menu of functions, the investor is buying access to the book-entry system, not a bespoke arrangement.
Because the agreement is bye-law-driven and SEBI-supervised, its terms are not immune from public-law scrutiny. The Supreme Court's approach to SEBI's regulation-making power in the securities space, as laid down in B.S.E. Brokers Forum, Bombay v. SEBI (2001) 3 SCC 482, where the Court upheld SEBI's fee regulations and registration requirements as a reasonable exercise of delegated power, applies with equal force to the bye-laws and regulations that shape the depository agreement. The investor's contract with the depository thus sits inside a tightly regulated statutory cage; its content is dictated less by the parties than by SEBI and the depository's own rule-book.
Section 6: surrender of certificates and the birth of the beneficial owner
Section 6 describes the act that converts paper into book entry. A person who has entered into a Section 5 agreement and already holds securities in physical form must surrender the certificate of security to the issuer through the participant. The issuer, on receipt, cancels the certificate and substitutes in its register of members the name of the depository as the registered owner. The depository, in turn, enters the name of that person in its own records as the beneficial owner. Dematerialisation is therefore a two-register event: the issuer's register now shows the depository, while the depository's register shows the investor.
This is the moment the Act's central duality crystallises. The investor surrenders the visible badge of ownership, the certificate, and receives in exchange an electronic credit and a new statutory status. The mechanics of surrender, including the role of the registrar and transfer agent and the consequences of defective certificates, are treated at length in our companion note on surrender of certificate of security. What matters for present purposes is that Section 6 is the engine that populates the depository's records with beneficial owners, and that nothing in the surrender diminishes the investor's economic entitlement, a proposition Section 10 then makes explicit.
Section 7: transfer of securities by book entry
Section 7 delivers the system's headline efficiency. Every depository shall, on receipt of intimation from a participant, register the transfer of a security in the name of the transferee. Where the beneficial owner or transferee so directs, the depository registers the transfer and, if either of them wishes to have custody of the certificate, intimates the issuer accordingly. In the ordinary case, however, transfer is effected purely by debiting the transferor's account and crediting the transferee's, no physical instrument moves, no transfer deed is lodged with the issuer, and the issuer's register continues to show only the depository.
The contrast with the paper regime is stark. Under the Companies Act route examined in our note on registration of transfer, transfer requires a duly stamped and executed instrument and registration by the company; under Section 7, transfer is a ledger entry between two demat accounts. This is why dematerialised securities are fungible and why settlement risk collapses. It is also why the locus of "ownership" for transfer purposes shifts: Section 10(1) deems the depository to be the registered owner for the purpose of effecting transfers, which is precisely what enables a transfer to be completed without disturbing the issuer's register at all.
Section 8: the investor's option to demat or stay on paper
Section 8 preserves investor choice at the point of allotment. Every person subscribing to securities offered by an issuer has the option either to receive the security certificate or to hold the securities with a depository. Where a person opts to hold with a depository, the issuer intimates the depository of the allotment details, and the depository enters the allottee's name in its records as the beneficial owner. The Act, in other words, makes dematerialisation voluntary at the level of the statute itself; it does not compel any holder to dematerialise.
This statutory optionality is doctrinally significant. Compulsion to dematerialise, where it exists today, flows not from the Depositories Act but from SEBI listing requirements and from the Companies Act read with the Companies (Prospectus and Allotment of Securities) Rules, which mandate demat-only issuance for listed and certain unlisted companies. The Act's own posture is permissive. That permissiveness fits the broader regulatory philosophy the Supreme Court endorsed in Sahara India Real Estate Corp. Ltd. v. SEBI (2012) 10 SCC 603, where the Court, while holding that an offer of securities to fifty or more persons is a public issue attracting SEBI's jurisdiction and the listing and demat machinery, treated dematerialisation as part of the investor-protection scaffolding rather than as an end in itself. Section 8 thus offers a right; the surrounding regulatory architecture increasingly converts the exercise of that right into a practical necessity.
Section 9: securities in fungible form
Section 9 states the legal premise that makes book-entry transfer possible: all securities held by a depository shall be dematerialised and shall be in a fungible form. Fungibility means that the securities lose their distinguishing certificate numbers and folio identities; one dematerialised share of a company is legally interchangeable with any other of the same class. A demat account does not record "certificate no. 0001-0100"; it records a quantity.
The doctrinal payoff is large. Because demat securities are fungible, the law of specific identification that governs physical certificates, which share is pledged, which is sold, falls away, and the depository can effect transfers and pledges by quantity rather than by instrument. This fungibility was central to the Supreme Court's reasoning in PTC India Financial Services Ltd. v. Venkateswarlu Kari (2022), discussed below, when it considered how a pledge over demat shares is created and enforced. Fungibility also explains the Act's drafting choice in Section 10 to disaggregate ownership: once the security is a fungible book entry, the only way to allocate rights is to assign the registered-owner role to the depository and the beneficial-owner role to the investor.
Section 10: the registered-owner / beneficial-owner divide
Section 10 is the constitutional heart of the depository's services. Sub-section (1) deems the depository to be the registered owner for the purpose of effecting transfer of ownership of a security on behalf of a beneficial owner. Sub-section (2) provides that, save as otherwise provided in sub-section (1), the depository as registered owner shall not have any voting rights or any other rights in respect of the securities. Sub-section (3) provides that the beneficial owner shall be entitled to all the rights and benefits and be subjected to all the liabilities in respect of the securities held by a depository.
The drafting is surgical. The depository's name on the issuer's register is a husk emptied of economic content, it exists for one purpose, to enable transfers, and for that purpose alone the depository is treated as owner. Every substantive incident of ownership, dividends, bonus, rights entitlements, the vote at the general meeting, and equally every liability, rests with the beneficial owner. The Supreme Court applied this very logic in Tata Consultancy Services Ltd. v. Cyrus Investments Pvt. Ltd. (2021) 9 SCC 449: shareholder rights and remedies, including the right to participate and vote, attach to the beneficial holding and are exercised by the beneficial owner notwithstanding that the issuer's register names a depository. Section 10 thus ensures that dematerialisation changes the form of holding without disturbing the substance of membership, a point that recurs throughout the case law on the Act.
Section 11: the register of beneficial owners
If Section 10 allocates rights, Section 11 records them. It requires every depository to maintain a register and an index of beneficial owners in the manner provided in the relevant provisions of the Companies Act dealing with registers and indexes of members. The depository's beneficial-owner register is, functionally, the demat-world equivalent of the company's register of members: it is the authoritative record of who beneficially owns what.
This register is what gives the beneficial owner's Section 10(3) entitlements their evidentiary teeth. When a company convenes a general meeting or declares a dividend, it ascertains entitlements by taking, from the depository, a list of beneficial owners as on the record date. The accuracy and integrity of this register therefore underpins the entire edifice of corporate democracy in dematerialised companies. It also ties back to the statutory definitions of depository, participant and beneficial owner, the register is the place where the abstract definition of "beneficial owner" becomes a concrete, name-by-name record with legal consequences.
Section 12 and the pledge of demat securities: PTC India
Section 12 permits a beneficial owner to create a pledge or hypothecation over securities held in a depository, subject to the bye-laws, by making an application to the depository through the participant; the depository then makes the requisite entry in its records, and that entry is evidence of the pledge. Regulation 58 of the SEBI (Depositories and Participants) Regulations elaborates the procedure, including the contentious requirement that, to invoke the pledge, the pledgee may have itself recorded as beneficial owner of the pledged securities.
For years this raised a hard question: does the depository regime displace the ordinary law of pledge under the Indian Contract Act, 1872, and does a pledgee who becomes the recorded beneficial owner thereby acquire the shares and extinguish the debt? The Bombay High Court in JRY Investments Pvt. Ltd. v. Deccan Leafine Services Ltd. had taken the view that demat securities, being incapable of physical delivery under Section 172 of the Contract Act, could not be pledged in the ordinary sense and were governed exclusively by the self-contained depository machinery. The Supreme Court decisively rejected that approach in PTC India Financial Services Ltd. v. Venkateswarlu Kari, 2022 SCC OnLine SC 608 (Civil Appeal No. 5443 of 2019, decided 12 May 2022), overruling JRY Investments.
The Court held that Section 12 does not define pledge or hypothecation and therefore borrows their established commercial meaning; the Depositories Act and the Contract Act must be read harmoniously, not as rivals. Crucially, the Court held that a pledgee's act of getting itself recorded as beneficial owner under Regulation 58 is a step en route to sale and does not by itself amount to a sale or to satisfaction of the debt; the pledgor's right of redemption under Section 177 of the Contract Act survives until an actual sale to a third party. PTC India is now the leading authority on the interface between the depository's services and the general law of secured transactions.
Section 14: the option to opt out and rematerialise
The services of a depository include the right to exit them. Section 14 gives a beneficial owner who wishes to opt out of a depository in respect of any security the right to inform the depository accordingly; the depository makes the appropriate entries in its records and intimates the issuer. The issuer must then, within thirty days of receipt of that intimation and after satisfaction of any prescribed conditions and payment of fees, issue the certificate of securities to the person who has opted out, this is rematerialisation, the mirror image of the Section 6 surrender.
Section 14 is the doctrinal counterweight to Section 8. Just as the Act refuses to compel an investor into demat at the allotment stage, it refuses to trap a beneficial owner inside the system thereafter. Read together, Sections 8 and 14 frame dematerialisation as a reversible election rather than a one-way door, the investor may enter book-entry holding, leave it, and re-enter it, security by security. The thirty-day outer limit on the issuer disciplines the exit and prevents the right from being defeated by delay, reinforcing the Act's investor-protection character.
It is worth noting what rematerialisation does not change. The opt-out under Section 14 affects only the form in which the holding is recorded; it does not alter the chain of title, create a transfer, or attract stamp duty as a conveyance, because no change of beneficial ownership occurs. The same person who was the beneficial owner in the depository's records becomes, on rematerialisation, the registered holder on the issuer's own register. In this sense Section 14 simply unwinds the Section 6 fiction: the depository's name is removed from the issuer's register and the investor's name is reinstated, restoring the pre-demat position. The right is exercisable security by security, so a holder may rematerialise part of a holding while leaving the rest in demat form, a flexibility that has practical value where, for example, an investor wishes to lodge physical certificates as security in a transaction that the demat pledge machinery does not conveniently accommodate.
Section 16: indemnity and the price of the services
The services come with statutory accountability. Section 16 provides that, without prejudice to other remedies, where any loss is caused to the beneficial owner due to the negligence of the depository or the participant, the depository shall indemnify that beneficial owner; and where the loss is caused by the negligence of a participant, the depository may in turn recover the amount from that participant. The depository is thus made the front-line guarantor of the integrity of its own book-entry system, with a right of indemnity over the erring DP behind it.
The practical bite of this allocation surfaced in the Karvy Stock Broking litigation, where client securities held in demat form were pledged by the broker without authority, exposing both lenders and clients to loss. The Securities Appellate Tribunal, in its December 2023 orders, directed SEBI, the National Stock Exchange and the National Securities Depository to restore the pledges in favour of the lender banks or to compensate them with the value of the underlying securities together with interest, a vivid illustration of how the depository sits at the centre of liability when the book-entry system is abused. Section 16, the SEBI (Depositories and Participants) Regulations, and the depository's bye-laws together translate the abstract promise of "services" into an enforceable standard of care.
The services read as an integrated whole
Stepping back, the services of a depository are best understood not as a list but as a closed loop. Section 5 admits the investor; Section 6 converts paper to book entry and creates the beneficial owner; Sections 7 and 9 make the holding transferable and fungible; Section 8 preserves the choice to enter, and Section 14 the choice to leave; Section 10 keeps economic ownership with the investor while lending the depository's name for transfer; Section 11 records it all; Section 12 lets the holding be pledged; and Section 16 guarantees the integrity of the whole. Each section presupposes the others.
The case law tracks this integration. PTC India could only reason as it did about pledge because Section 9 fungibility and Section 10 duality were already in place; Tata Consultancy Services could vindicate shareholder rights only because Section 10(3) lodges those rights in the beneficial owner; and Sahara and B.S.E. Brokers Forum situate the entire apparatus within SEBI's protective regulatory jurisdiction. For the examinee, the safest framing is this: the "services of a depository" are the statutory means by which ownership is dematerialised without being diminished, paper is replaced by record without the holder losing a single incident of membership. To see how these services connect upstream to the very existence of a depository, revisit the Depositories Act hub and the chapter on the certificate of commencement of business, which a depository must obtain before it may render any of these services at all.
Frequently asked questions
What exactly are the "services of a depository" under the Depositories Act, 1996?
They are the bundle of statutory functions a depository performs once an investor signs up under Section 5: holding securities in dematerialised, fungible form (Section 9), recording the investor as beneficial owner on surrender of paper (Section 6), registering transfers by book entry (Section 7), offering the option to hold in demat or on paper (Section 8), permitting pledge (Section 12), and allowing rematerialisation on opting out (Section 14). The services are accessed only through a depository participant, never directly.
Who owns a dematerialised share, the depository or the investor?
Both, but in different senses. Under Section 10, the depository is the registered owner on the issuer's register, but solely for the purpose of effecting transfers and with no voting or other rights. The investor is the beneficial owner and holds every economic right and liability of ownership. The Supreme Court applied this divide in Tata Consultancy Services Ltd. v. Cyrus Investments Pvt. Ltd. (2021) 9 SCC 449, where shareholder rights attached to the beneficial holding.
Can dematerialised shares be pledged, and what did PTC India decide?
Yes. Section 12 allows a beneficial owner to pledge demat securities, with Regulation 58 of the SEBI (Depositories and Participants) Regulations prescribing the procedure. In PTC India Financial Services Ltd. v. Venkateswarlu Kari, 2022 SCC OnLine SC 608 (decided 12 May 2022), the Supreme Court held that the Depositories Act and the Contract Act, 1872 must be read harmoniously, that a pledgee recording itself as beneficial owner under Regulation 58 is only a step toward sale and does not extinguish the debt, and that the pledgor's right of redemption under Section 177 of the Contract Act survives until an actual third-party sale. It overruled the Bombay High Court's view in JRY Investments Pvt. Ltd. v. Deccan Leafine Services Ltd.
Is dematerialisation compulsory under the Depositories Act?
Not under the Act itself. Section 8 expressly gives every subscriber the option to receive a physical certificate or to hold with a depository, and Section 14 lets a beneficial owner opt out and rematerialise within thirty days. Compulsion to dematerialise flows from SEBI listing norms and the Companies Act read with the Companies (Prospectus and Allotment of Securities) Rules, not from the Depositories Act, which remains permissive.
What is the significance of securities being held in "fungible" form under Section 9?
Fungibility means demat securities lose their certificate numbers and folio identities, so one share of a class is legally interchangeable with another. This is what allows transfers and pledges to be effected by quantity rather than by identifying a specific certificate, and it underpins the book-entry settlement system. The Supreme Court relied on this feature in PTC India when analysing how a pledge over demat shares is created and enforced.
What liability does a depository bear if its services fail?
Section 16 makes the depository indemnify a beneficial owner for any loss caused by the negligence of the depository or its participant, with a right to recover from a negligent participant. The Karvy Stock Broking matter illustrates the stakes: in December 2023 the Securities Appellate Tribunal directed SEBI, NSE and NSDL to restore unauthorisedly invoked pledges or compensate the lender banks with the value of the securities plus interest, showing how the depository sits at the centre of liability when the book-entry system is abused.
