Conversion of a Pvt. Ltd. / OPC etc. is the process of changing the type of business entity from one form to another. This is usually done for reasons such as taxation, compliance, or liability protection.

The most common types of business entities in India are:

• Private Limited Companies (Pvt. Ltd.)
• One Person Companies (OPC)
• Public Limited Companies
• Limited Liability Partnerships (LLPs)

All types of business entities in India can be converted to any other type of business entity. However, there are some special rules and regulations that apply to certain types of conversions. For example, an OPC cannot be converted to a Section 8 company.

The process of converting a business entity from one form to another can be complex and time-consuming. It is important to consult with a qualified professional to ensure that the conversion is done correctly.

The documents required for conversion vary depending on the type of entities involved. However, some of the most common documents required include:

• Special resolution at a general meeting of the company
• Copy of the company’s Memorandum of Association (MOA) and Articles of Association (AOA)
• Declaration from the directors that the company is solvent
• Application for conversion
• Payment of applicable conversion fees

The time it takes to convert a business entity varies depending on the complexity of the conversion and the workload of the MCA. However, it is generally expected to take at least 2-3 months to complete the conversion process.
