Hi Aastha,

If your family business is an officially registered business, then you can absolutely obtain a work experience certificate that shall bear your role in the business and the time period for which you worked for. It should be approved from a supervisor or a manager.

Your business's official bank account should be registered with your business during the time of its foundation, and the salary that you will receive from this bank account will act as a solid proof of your employment history. When you get your pay from the business's official account, you will have to obtain a bank statement reflecting the period from the first to the last month.

You won't require an offer letter, but your employer should provide you with a notepad carrying the company's official name and logo mentioning your role and start and end dates for approval by your manager.

Hope this helps. Please feel free to reach out in case of any doubts. Best of luck!
