Dematerialisation and Rematerialisation are procedural mechanisms used in the Indian securities market to convert securities between physical and electronic form. These processes operate within the depository framework and apply to investors holding securities either as physical certificates or in Dematerialised format.
An understanding of how these processes function provides context on how securities are recorded, transferred, and maintained under the prevailing regulatory structure.
Dematerialisation of shares refers to the process through which physical share certificates are converted into electronic form and recorded in a Demat account. Under India’s securities market framework, Dematerialisation enables shares to be held and transferred electronically through recognised depositories rather than in paper format.
In this system, securities are maintained in Dematerialised form in Demat accounts opened with Depository Participants (DPs). These DPs act as intermediaries between investors and central depositories such as the National Securities Depository Limited (NSDL) and Central Depository Services (India) Limited (CDSL), which hold securities in electronic custody.
Physical share certificates are converted into electronic holdings recorded against a Demat account
The process is initiated by submitting the physical certificates along with a Dematerialisation Request Form (DRF) to the DP
The DP forwards the request to the issuing company’s Registrar and Transfer Agent (RTA) for verification
Upon confirmation, the corresponding number of shares is credited electronically to the Demat account
Once Dematerialised, shares exist only in electronic form and are settled and transferred through depository systems in accordance with applicable regulatory and exchange processes.
Rematerialisation of shares refers to the process through which securities held in electronic form in a Demat account are converted back into physical share certificates. This process operates within India’s depository framework and is carried out through authorised Depository Participants (DPs) and the issuing company’s Registrar and Transfer Agent (RTA).
Under Rematerialisation, an account holder submits a formal request to convert Dematerialised holdings into physical form. Upon verification of the request and holdings, physical certificates are issued in place of the electronic balance, and the corresponding securities are debited from the Demat account.
It involves converting securities from Demat form into physical share certificates
The process is initiated by submitting a Rematerialisation Request Form (RRF) to the Depository Participant
The Registrar and Transfer Agent verifies the request and issues physical certificates upon approval
Once Rematerialised, the shares are no longer available for electronic trading unless Dematerialised again
Rematerialisation remains a permitted facility under depository regulations, allowing securities to be held in physical form where required under specific ownership, documentation, or procedural contexts.
The difference between Dematerialisation and Rematerialisation lies in the direction and purpose of conversion of securities within India’s depository framework. These processes, commonly referred to as Demat and Remat, govern whether securities are held electronically through a Demat account or issued as physical certificates.

Transaction Handling:
Securities in Demat form are settled electronically through depository systems, while transactions involving Rematerialised certificates require physical handling and manual processing.
Regulatory Context:
As per SEBI norms effective from April 1, 2019, transfers of listed securities are required to be executed only in Dematerialised form. Rematerialisation remains available as a facility for holding securities in physical format but does not support exchange-based transfers.
Account Dependency:
Dematerialisation requires an active Demat account, whereas Rematerialisation results in the closure of electronic holdings for the Rematerialised quantity.
Together, these points explain the structural and operational difference between Demat and Remat, clarifying how each process functions within the securities holding lifecycle.
Dematerialisation follows a defined process through which physical securities are converted into electronic form via a Depository Participant (DP)
1. Submission of Documents: Physical share certificates and a duly filled Dematerialisation Request Form (DRF) are submitted to the DP.
2. Verification by DP: The DP verifies the documents and forwards the DRF along with certificates to the issuer's RTA.
3. R&T Agent Processing: The R&T Agent verifies the authenticity of certificates and investor details.
4. Confirmation and Credit: Upon approval, the R&T Agent informs the DP and the depository. The shares are then credited to the Demat account electronically.
Rematerialisation is the process through which securities held in dematerialised form are converted back into physical certificates through a Depository Participant (DP).
1. Initiate Request: Submit a Rematerialisation Request Form (RRF) to your DP, requesting conversion of electronic holdings into physical certificates.
2. DP Verification: The DP checks the request for completeness and forwards it to the R&T Agent.
3. R&T Agent Processing: The R&T Agent verifies the Demat holdings and approves the request.
4. Physical Certificate Issuance: The company’s registrar issues physical share certificates to the investor.
Dematerialisation and rematerialisation serve different functional roles within the securities holding and transfer framework.
Facilitates holding and transfer of securities in electronic form through the depository system
Reduces dependency on physical certificates, thereby limiting risks associated with physical handling
Supports electronic settlement and transfer processes prescribed by stock exchanges and depositories
Aligns securities holding with the settlement and trading mechanisms used in the Indian securities market
Allows conversion of dematerialised securities back into physical certificate form
Supports situations where physical documentation is required under specific legal or procedural contexts
Enables movement of securities outside the electronic holding framework when requested by the investor
Depository Participants and Registrar & Transfer Agents perform defined functions within the securities holding and transfer process.
Depository Participants (DPs): They act as intermediaries between investors and central depositories like NSDL and CDSL. DPs help facilitate both Dematerialisation and Rematerialisation.
Registrar and Transfer Agents (R&T Agents): They manage records, verify transactions, and issue physical share certificates during Rematerialisation.
Charges related to dematerialisation and rematerialisation are determined by the Depository Participant and may vary based on internal tariff structures and issuer arrangements.
| Charge Type | Description |
|---|---|
Dematerialisation Charges |
Nominal fee per certificate or processing charge based on DP's pricing structure; some DPs offer it free. |
Rematerialisation Charges |
Typically a per-certificate fee or flat charge per 100 securities; generally higher than demat charges due to printing and dispatch costs. |
Additional Fees |
Includes transaction charges, GST at applicable rates, and courier fees (varies by DP and issuer) |
Dematerialisation and rematerialisation form part of the operational framework governing securities holding in India. While dematerialisation supports electronic custody and exchange-based transactions, rematerialisation enables conversion back to physical form under prescribed procedures.

Yes. Physical share certificates can be submitted for partial dematerialisation, provided they belong to the same ISIN and comply with issuer and depository requirements.
No. Rematerialisation is optional and is carried out only when requested by the investor.
The status can be tracked through the Depository Participant (DP), via periodic account statements, or by using the online tracking facilities available on the NSDL or CDSL websites using the request number.
No. Shares must be credited to a demat account in electronic form before they can be traded.
Physical share certificates remain valid. However, transfers of listed securities are required to be carried out in dematerialised form under prevailing regulations.
Dematerialisation converts physical share certificates into electronic form, while rematerialisation converts electronic holdings back into physical certificates through a Depository Participant.
Rematerialisation of shares is the process of converting securities held in electronic form in a demat account into physical share certificates by submitting a Remat Request Form (RRF) through a Depository Participant.
Demutualisation refers to the conversion of a stock exchange from a member-owned entity into a shareholder-owned company. Dematerialisation refers to the conversion of physical share certificates into electronic form.

Yes. Securities held in a demat account can be converted back into physical certificates through rematerialisation by submitting a Remat Request Form (RRF) to the Depository Participant.
Demat holdings carry lower risk as securities are stored electronically, reducing exposure to loss, theft, or damage. Remat holdings involve higher physical risk since ownership is represented through paper certificates that may be lost, damaged, or forged.
Rematerialisation typically takes around 30 days from submission of the Remat Request Form (RRF), subject to processing by the Registrar and Transfer Agent (RTA).
Rematerialisation charges vary by Depository Participant and may include per-certificate fees, service charges, and applicable taxes, as specified in the DP’s tariff schedule.
