Functions of Depository Participant: Dematerialisation Explained

Dematerialisation is the conversion of physical share certificates into electronic form in a depository account. You submit a Demat Request Form and the certificates to your Depository Participant (DP). The DP verifies them, sends the request to the issuer or RTA, and the securities are credited once the issuer confirms. Learn the steps in order.

What this chapter covers

This chapter covers how physical securities become electronic holdings. The Depository Participant (DP) is the link between the investor and the depository (NSDL or CDSL). The chapter follows one request from start to finish: the investor submits a request, the DP checks it, the issuer or its Registrar and Transfer Agent (RTA) processes it, and the depository credits the account.

You will study the request form and its documents, what the DP must check and keep safe, how the issuer or RTA confirms the request, and what happens in special cases. These include partial demat, shares under lock-in, and transmission. The chapter ends with rematerialisation, which is the reverse process.

This chapter links to other parts of the paper. It builds on the structure of the depository system, account opening and the legal framework. It also leads into transfers, pledge, corporate actions and settlement. If you understand how a security enters the depository, those later chapters are easier. Check your workbook for the exact process steps, timelines and conditions, because the exam tests them closely.

NISM Series VI is a 100-question, 100-mark exam with a 60% pass mark and negative marking of 25% of the marks assigned to each question. Dematerialisation is a core DP function, so questions here test process knowledge that you can learn exactly. The questions are usually about who does what, in what order, and under which conditions. Once you know the sequence, you can answer them quickly and avoid wrong guesses that cost marks. The chapter also supports later topics such as transmission, pledge and corporate actions, so the effort pays off twice.

Functions of Depository Participant - Dematerialisation: topics in the order to study them

  1. 1Dematerialisation Concept and Process OverviewStart here to see the whole flow and the roles of investor, DP, depository, issuer and RTA before learning details.
  2. 2Demat Request Form (DRF) and DocumentationThe DRF is the first step in the process, so learn what is submitted and what the form must contain next.
  3. 3DP Responsibilities and Handling of SecuritiesAfter submission, the DP verifies, records and forwards the request. Learn its duties and safeguards in this step.
  4. 4Processing by Issuer/RTA and TimelinesThis follows the DP's forwarding of the request. Learn what the issuer or RTA does and the time limits that apply.
  5. 5Special Cases: Partial Demat, Lock-in and TransmissionLearn these exceptions only after the normal process is clear, so you can spot how each case differs.
  6. 6Rematerialisation and Related RulesStudy the reverse process last. It is easier when you can compare it with the demat flow you already know.

How to prepare Functions of Depository Participant - Dematerialisation

This chapter is a process chapter, so prepare it by sequence and by exact rules. Do not try to memorise isolated facts.

  1. Read the chapter once and draw the demat flow on one page: investor, DP, depository, issuer or RTA, and credit to the account.
  2. Learn the DRF and its documents. Note who signs, what is attached, and what the DP checks before accepting it.
  3. Make a table in your notes of each party's duties. For each duty, write who performs it and at which step.
  4. Copy the timelines and limits exactly from your current NISM workbook. Revise them daily until you can recall them without looking.
  5. Study each special case as a list of how it differs from the normal flow. Do the same for rematerialisation, using the demat flow as your base.
  6. Practise MCQs after each topic. For every wrong answer, write down the exact rule you missed.
  7. Take timed mixed sets. Skip a question only if you cannot narrow the options, because wrong answers carry negative marks.

Common mistakes in Functions of Depository Participant - Dematerialisation

  • Mixing up the order of steps in the demat process.

    Fix: Draw the flow from investor to DP to issuer or RTA to depository to credit. Retell it aloud until the order is automatic.

  • Confusing the roles of the DP, the depository and the issuer or RTA.

    Fix: Write one line for each party's role. Before choosing an answer, ask which party actually performs the action in the question.

  • Recalling timelines from memory or from outside sources.

    Fix: Take every limit and timeline from the current NISM workbook. Revise them separately and often.

  • Treating special cases as the normal process.

    Fix: For each special case, note one line on what differs. Look for the keyword in the question before answering.

  • Treating rematerialisation as just a mirror image of demat.

    Fix: Study its own steps and conditions from the workbook, then compare them with demat to find the differences.

  • Guessing freely on unfamiliar questions.

    Fix: Eliminate options using the process order and party roles first. Guess only when you have narrowed it down.

Last-day revision: Functions of Depository Participant - Dematerialisation

  • Dematerialisation converts physical securities into electronic form in a depository account.
  • The investor deals with the DP. The DP is the depository's agent for this purpose.
  • The investor must hold an account with the DP before submitting a demat request.
  • A Demat Request Form accompanies the physical certificates submitted to the DP.
  • The DP checks the form and certificates before sending the request onward.
  • The issuer or its RTA confirms the request to the depository after processing it.
  • The depository credits the investor's account only after the issuer or RTA confirms.
  • Know the workbook's exact timeline for processing a request, and who must meet it.
  • Partial demat, lock-in and transmission each follow special rules that differ from the normal flow.
  • Rematerialisation is the reverse process: electronic holdings are converted back to physical certificates.
  • Use workbook wording for conditions. Words like 'only', 'all' and 'must' often decide the answer.

Functions of Depository Participant - Dematerialisation: frequently asked questions

What is the role of a Depository Participant in dematerialisation?

The DP is the investor's point of contact with the depository. It accepts the demat request and documents, checks them, and forwards the request for processing. It then reflects the credit in the investor's account once the process is complete.

Do I need to memorise timelines for this chapter?

Yes. Timelines and conditions are tested directly in multiple choice questions. Take them from the current NISM workbook, because the exam follows it, and revise them often.

How is rematerialisation different from dematerialisation?

Dematerialisation converts physical certificates into electronic holdings. Rematerialisation does the reverse and converts electronic holdings back into physical certificates. Learn it as its own process with its own conditions.

Is there negative marking in NISM Series VI?

Yes. A wrong answer costs 25% of the marks assigned to that question. The pass mark is 60%, so avoid blind guesses and use elimination first.
