Conversion of Business Entities: Meaning and Types

Updated 11 October 2026 · Fact-checked

Conversion of a business entity means changing the legal form of a business, for example from a sole proprietorship or partnership to a company, from one class of company to another, or from a company to an LLP. The law lays down who may convert, the conditions, and what happens to existing debts and liabilities.

Understand Conversion of Business Entities: Meaning and Types

A business is run through a legal form. It may be a sole proprietorship, a partnership firm, a Limited Liability Partnership (LLP) or a company. Over time the form that suited the business at the start may stop suiting it. Conversion is the legal route by which the business changes its form and carries on in the new one.

Why do businesses convert? The common reasons are to get limited liability, to raise capital from outside investors, to gain a separate legal identity and perpetual succession, to improve credibility with banks and customers, or to cut compliance cost. A growing sole proprietor may move to a company for funding. A private company that no longer needs heavy compliance may move to an LLP.

There are three broad routes you must know.

Non-company to company: a sole proprietorship or partnership firm (and other entities such as LLP, society or co-operative society) becoming a company. The Companies Act, 2013 deals with this under the Part on companies authorised to register, and section 374 sets the obligations of a company seeking registration under that Part.
Company to company of another class: a company registered under the Act converts itself into a company of another class, for example private to public, public to private, or limited to unlimited. Section 18 permits this by altering the memorandum and articles.
Company to LLP: a private company can convert under section 56 of the LLP Act, 2008 and the Third Schedule. An unlisted public company can convert under section 57 and the Fourth Schedule. A listed public company cannot use this route.

One principle runs through all routes. Conversion changes the form, not the business. Under section 18(3), registration on conversion does not affect any debts, liabilities, obligations or contracts incurred before conversion, and they can be enforced as if the conversion had not happened. The Registrar closes the former registration and issues a fresh certificate of incorporation.

For the exam, keep the three routes, the section for each, the conditions and the effect on liabilities clear. The detailed procedures are covered in the related topics.

Key rules to remember

Conversion of companies already registered: Section 18(1): a company of any class may convert to a company of another class by altering its memorandum and articles; Applies only to companies already registered under the Act. The Registrar closes the former registration and issues a certificate of incorporation as in first registration (s 18(2)).
Effect on past liabilities: Section 18(3): conversion does not affect debts, liabilities, obligations or contracts incurred before conversion; They remain enforceable as if no conversion had taken place.
Private company to LLP: LLP Act, 2008, section 56 read with the Third Schedule; Available to a private company.
Unlisted public company to LLP: LLP Act, 2008, section 57 read with the Fourth Schedule; Available only to an unlisted public company, not a listed one.
Obligations of an entity registering as a company (section 374): (a) secured creditors' consent or no objection; (b) newspaper notice, one English and one vernacular; (c) notarised affidavit from all members or partners on filing papers for dissolution of the earlier entity; (d) other prescribed conditions; Proviso: on registration as a company, an LLP is deemed dissolved under the LLP Act without any further act or deed.

Common mistakes in Conversion of Business Entities: Meaning and Types

Saying a listed public company can convert into an LLP.
Students remember that public companies can convert and forget the word 'unlisted' in section 57.
Fix: Write 'unlisted public company' every time you cite section 57 and the Fourth Schedule.
Treating conversion under section 18 as the same as registering a partnership firm as a company.
Both are called conversion, so the provisions get mixed up.
Fix: Section 18 is for companies already registered under the Act. A firm or LLP becoming a company falls under the registration provisions, including section 374.
Writing that old debts are wiped out after conversion.
Students confuse the new certificate with a new business.
Fix: Quote section 18(3): earlier debts, liabilities, obligations and contracts are unaffected and enforceable.
Mixing up the Schedules for LLP conversion.
Both sections look alike and have numbered Schedules.
Fix: Private company: section 56, Third Schedule. Unlisted public company: section 57, Fourth Schedule.
Forgetting that an LLP is deemed dissolved on becoming a company.
Students focus on the affidavit and notice and skip the proviso to section 374.
Fix: Add the line: on registration as a company, the LLP is deemed dissolved under the LLP Act without any further act or deed.

Worked examples

Example 1

Explain the meaning of conversion of a business entity and name the main routes of conversion under the Companies Act, 2013 and the LLP Act, 2008.

Show the solution

Meaning: conversion is the legal change of a business from one form to another, with the business continuing in the new form.
Route 1: a non-company entity such as a partnership firm, sole proprietorship or LLP becomes a company. Section 374 of the Companies Act lists the obligations of such an entity.
Route 2: a registered company becomes a company of another class, such as private to public. Section 18(1) allows this by altering the memorandum and articles.
Route 3: a company becomes an LLP. A private company uses section 56 and the Third Schedule. An unlisted public company uses section 57 and the Fourth Schedule.
Effect: under section 18(3), past debts and contracts remain enforceable after a section 18 conversion.

Answer: Conversion is a change in the legal form of a business. The main routes are non-company to company (section 374), company to another class of company (section 18), and private or unlisted public company to LLP (sections 56 and 57 of the LLP Act).

Example 2

Rajan & Sons, a partnership firm in Pune, wishes to register as a company under the Companies Act, 2013. It has a secured loan from a bank. Advise the firm on what it must do before registration.

Show the solution

Provision: section 374 sets obligations for an entity seeking registration as a company under that Part.
Secured creditors: the firm must ensure the bank, as a secured creditor, has consented or given no objection to the registration.
Public notice: it must publish an advertisement in a newspaper, one in English and one in a vernacular language, in the prescribed form, giving notice of the registration, seeking objections and addressing them suitably.
Affidavit: it must file a notarised affidavit from all the partners stating that, on registration, the necessary documents will be submitted to the authority with which the firm was registered, for its dissolution as a partnership firm.
Other conditions: it must comply with any other prescribed conditions.

Answer: Rajan & Sons must obtain the bank's consent or no objection, publish the English and vernacular newspaper notices and address objections, file a notarised affidavit from all partners for dissolution of the firm, and meet any other prescribed conditions, as required by section 374.

Exam tips

Always name the section and the Act with the route. Marks are given for the provision first, then application.
For a 'listed or unlisted' fact pattern, check the status of the public company before choosing section 57.
In case-study answers, end with a one-line conclusion such as 'the conversion is permissible' or 'the company cannot convert'.
Learn the three routes as a list. Short notes on 'types of conversion' are easiest to score with this structure.
Do not copy long text of the Act. Paraphrase the conditions in short points.

Conversion of Business Entities: Meaning and Types: frequently asked questions

What is conversion of a business entity?

It is the legal change of a business from one form to another, such as a partnership firm to a company or a company to an LLP. The business continues, but under a different legal structure and registration.

Why do businesses convert from one form to another?

Common reasons are limited liability, easier fundraising, separate legal identity, better credibility, and lower compliance burden. A growing business often moves to a company, while a small closely held company may move to an LLP.

Can a listed public company convert into an LLP?

No. Section 57 of the LLP Act allows only an unlisted public company to convert into an LLP. A private company converts under section 56.
