Requiring the submission of three names during the legal entity registration process in many countries serves several purposes:

1. Availability: Submitting multiple name options increases the likelihood of finding a unique and available name for the legal entity. This helps prevent confusion or conflicts with existing businesses or registered trademarks.

2. Compliance: Legal entity names must comply with specific regulations and guidelines set by the government or regulatory bodies. By submitting multiple names, it allows the authorities to review and determine if any of the proposed names violate these regulations.

3. Alternatives: In case the first choice of name is already taken or deemed ineligible for registration, having alternative names provides options to proceed with the registration process without delays. It avoids the need to go back and forth for name changes or resubmissions.

4. Clarity and Specificity: By submitting multiple names, it allows the authorities to review and select a name that clearly represents the nature, purpose, or activities of the legal entity. This helps ensure transparency and avoid misleading or ambiguous names.

5. Name Approval Process: In some jurisdictions, the registration authorities may have specific procedures for name approval, including name availability searches or public notifications. By submitting multiple names, it allows for a more efficient name approval process, as the authorities can review and process multiple options simultaneously.

It's important to note that the exact requirements and processes related to name submission may vary from country to country. It is advisable to consult the specific regulations and guidelines provided by the relevant government or registration authorities in the country where you plan to register a legal entity.
