## Public Offer of Securities to be in Dematerialised Form — Section 29
### The three buckets
Section 29 splits companies into three categories with different demat obligations:
| Category | Obligation |
|---|---|
| (a) Companies making a public offer, plus other prescribed companies | Must issue securities only in dematerialised form |
| (b) Prescribed unlisted companies | Their securities shall be held or transferred only in dematerialised form |
| (c) Any other company | Optional — may issue in physical or demat form, and may convert existing physical securities into demat |
### Why demat is being pushed
Dematerialisation eliminates the risks of physical certificates — forgery, loss, transfer-deed fraud, signature mismatch, and bad delivery. It also gives the regulator a complete audit trail of beneficial ownership.
### Compliance framework
Companies issuing in demat form must comply with:
- The Depositories Act, 1996 and its regulations, AND
- Rules 9 and 9A of the Companies (Prospectus and Allotment of Securities) Rules, 2014:
- Rule 9 — Dematerialisation of Securities (general)
- Rule 9A — Issue of Securities in Dematerialised Form by Unlisted Public Companies
