Depository System and Dematerialisation under the Depositories Act, 1996

Updated 11 October 2026 · Fact-checked

A depository is a SEBI-registered company that holds securities in electronic (dematerialised) form and records their transfer. Investors hold securities through depository participants. To answer exam questions, define the term from the Depositories Act, 1996, explain how the system works, state the benefit or rule asked, and conclude.

Understand Depository System and Dematerialisation

Earlier, you held shares as paper certificates. Paper can be lost, forged or damaged. Transfer needed a signed form and took time. The depository system replaces paper with electronic records.

Dematerialisation means converting physical certificates into electronic form held with a depository. Rematerialisation is the reverse: the investor opts out and gets physical certificates again. Section 8 of the Depositories Act, 1996 gives every person subscribing to securities the option either to receive certificates or to hold securities with a depository.

The system has four players. The issuer makes the issue of securities. The depository keeps the electronic records. The participant is the depository's agent and the investor's contact point. The beneficial owner is the investor. Under section 4, a depository enters into an agreement with one or more participants as its agent. In India the two depositories are NSDL and CDSL.

A key idea is the split between registered owner and beneficial owner. The depository's name appears in the issuer's register, so it is the registered owner. Section 10 says it is deemed the registered owner only for effecting transfer of ownership on behalf of the beneficial owner. It has no voting rights or other rights in the securities. The beneficial owner gets all the rights and benefits and bears all the liabilities.

Securities held by a depository are dematerialised and fungible (section 9). Fungible means one share is interchangeable with another of the same kind, so individual certificate numbers do not matter. A custodian is a different concept: it safeguards assets for clients such as institutions. A depository holds securities in electronic form and records ownership transfers. Do not mix the two.

Key rules to remember

Beneficial owner (s. 2(1)(a))
Beneficial owner = person whose name is recorded as such with a depository
The investor. Entitled to all rights and benefits and subject to all liabilities (s. 10(3)).
Registered owner (s. 2(1)(j))
Registered owner = depository whose name is entered as such in the register of the issuer
Deemed owner only to effect transfers (s. 10(1)). No voting or other rights (s. 10(2)).
Depository (s. 2(1)(e))
Depository = company registered under the Companies Act + certificate of registration under s. 12(1A) of the SEBI Act
The Act's definition refers to the Companies Act, 1956; read it as the Act is worded.
Participant (s. 2(1)(g))
Participant = person registered under s. 12(1A) of the SEBI Act, 1992
Acts as the depository's agent under s. 4.
Option to hold (s. 8)
Subscriber's option: receive certificates OR hold with a depository
If demat is chosen, the issuer intimates the depository, which records the allottee as beneficial owner.
Fungibility (s. 9(1))
All securities held by a depository = dematerialised + fungible
Securities of the same class are interchangeable.
Transfer (s. 7(1))
Participant intimates → depository registers transfer in transferee's name
No certificate or transfer deed is needed in the depository.

How to solve Depository System and Dematerialisation questions

Use this method for definition, explanation and short-note questions on the depository system.

  1. 1Identify what is asked: a definition, a comparison, a benefit, or a rule on rights.
  2. 2Start with the term as defined in section 2(1) of the Depositories Act, 1996, in plain words.
  3. 3Name the parties involved: issuer, depository, participant, beneficial owner.
  4. 4Explain how the system works for the point asked, citing the relevant section (4, 7, 8, 9 or 10).
  5. 5Add a brief contrast, such as physical versus demat, or registered owner versus beneficial owner.
  6. 6Give a conclusion that answers the question directly.

Quickest way: Four-party chain

When to use it: For short notes and 'who has which right' questions when time is tight.

  1. Write the chain: Issuer → Depository → Participant → Beneficial owner.
  2. Attach one section to each link: s. 8 (option), s. 4 (agent), s. 7 (transfer), s. 10 (rights).
  3. Write one line on each party's role.
  4. Close with the point that the depository is registered owner but the investor enjoys the rights.

Common mistakes in Depository System and Dematerialisation

  • Saying the depository has voting rights because it is the registered owner.

    The word 'owner' suggests full ownership.

    Fix: Section 10(2) says the depository has no voting or other rights. The beneficial owner holds all rights and benefits.

  • Treating a depository and a custodian as the same.

    Both hold securities for others.

    Fix: A depository is registered under the SEBI Act and holds securities in demat form and records ownership transfer. A custodian safeguards clients' assets, mostly for institutions. Compare the functions, not the word 'hold'.

  • Assuming demat is compulsory under section 8.

    Demat is now the usual practice, so the option is forgotten.

    Fix: Section 8(1) gives the subscriber the option. Quote it as it is; do not claim a mandatory rule without a provision supporting it.

  • Mixing up participant and beneficial owner.

    Both deal with the investor's account.

    Fix: A participant is a registered intermediary acting as the depository's agent. The beneficial owner is the investor whose name is recorded with the depository.

  • Writing dematerialisation and rematerialisation as the same thing.

    Both words sound alike.

    Fix: Demat converts paper into electronic records. Remat is opting out of the depository to get certificates again.

  • Forgetting what fungible means.

    It is mentioned in one line of the Act and skipped.

    Fix: Define it: securities of the same class are interchangeable, so no certificate numbers are tracked. Cite section 9(1).

Worked examples

Example 1

Ravi holds 500 shares of Tata Motors in demat form through a participant of NSDL. At the company's general meeting, NSDL claims to vote on these shares as the registered owner. Is the claim valid?

Show the solution
  1. Provision: under section 10(1) of the Depositories Act, 1996 a depository is deemed the registered owner only for effecting transfer of ownership on behalf of a beneficial owner.
  2. Section 10(2): save as provided in section 10(1), the depository as registered owner has no voting rights or any other rights in respect of the securities.
  3. Section 10(3): the beneficial owner is entitled to all the rights and benefits and is subject to all the liabilities.
  4. Analysis: Ravi's name is recorded with the depository, so he is the beneficial owner of the 500 shares.

Answer: NSDL's claim is not valid. It has no voting rights. Ravi, as beneficial owner, is entitled to vote and receive all benefits.

Example 2

Explain the options available to a person subscribing to securities, and what happens if the person chooses to hold them with a depository.

Show the solution
  1. Provision: section 8(1) gives every person subscribing to securities offered by an issuer the option either to receive security certificates or to hold securities with a depository.
  2. If the person opts for a depository, section 8(2) requires the issuer to intimate the depository the details of allotment.
  3. On receipt, the depository enters the name of the allottee in its records as beneficial owner of that security.
  4. Result: the securities are held in dematerialised, fungible form (section 9(1)) and later transfers are registered on a participant's intimation (section 7(1)).

Answer: The subscriber may choose physical certificates or depository holding. If the depository is chosen, the issuer informs the depository, which records the allottee as beneficial owner.

Exam tips

  • Learn the definitions in section 2(1) almost word for word; examiners reward exact terms for beneficial owner, registered owner, participant and depository.
  • In a 'rights' question, always contrast registered owner with beneficial owner and cite section 10.
  • For benefits of demat, give points such as safety from loss or forgery, faster transfer and lower paperwork, each with one line of reasoning.
  • Use the answer pattern: provision, facts, conclusion. Write the section number beside each rule.
  • Do not claim penalty amounts or timelines unless you are sure. Section 19D penalty for delay in demat is up to one lakh rupees per day, subject to a maximum of one crore rupees.

Under section 2(1)(a), it is a person whose name is recorded as such with a depository. The beneficial owner gets all the rights and benefits and bears all the liabilities in respect of the securities (section 10(3)).

Are securities in a depository fungible?

Yes. Section 9(1) says all securities held by a depository are dematerialised and in fungible form. This means securities of the same kind are interchangeable.
