Paid maternity leave in unregistered company

Whether the company is a registered or an unregistered firm, until and unless you are not on the pay rolls of the company, i.e., if you were not appointed by the company by giving an appointment letter or employment offer letter and there are no details of the salary in the aabsence of salary slip, you will not be considered as an employee of that company.

You have stated that you were being paid by Gpay and that you were working from remote, it means you do not even know where the company is located.

In that situation your claim for any priveleges as per law will not be maintainable
