# Conversion of Companies Already Registered (Section 18)
## What is Conversion?
A company already registered under the Act can be converted into another class of company (e.g., private to public, OPC to private, public to private).
## Procedure for Conversion
### Step 1 — Alter MOA and AOA
The company must alter its MOA and AOA in compliance with the Act's provisions for that new class.
### Step 2 — Application to ROC
- The company files an application with the ROC for conversion
- The ROC verifies compliance with registration requirements of the new class
- ROC closes the former registration of the company
### Step 3 — Issue of Fresh Certificate of Incorporation
After registering the necessary documents, the ROC issues a fresh certificate of incorporation for the newly converted company — similar to the original registration process.
## Critical Protection: Continuity of Liabilities (Sec 18(3))
> Conversion does NOT affect:
> - Any debts
> - Any liabilities
> - Any obligations
> - Any contracts entered into before conversion
These can be enforced against the converted company as if conversion had never happened. The corporate entity continues — only its class changes.
## Key Insight
Conversion is a change of legal form, not a change of legal entity. The company's identity, PAN, history, and liabilities all continue.
