Father in Law property for Address proof

It is generally not possible to use your father's address as the principal place of business for a property that you own, even if you have obtained a no objection certificate (NOC) from your father. This is because the principal place of business is typically defined as the primary location where a business is conducted or operated. In the case of a property, the principal place of business is typically the address where the property is located.

In general, it is best to use the actual address of the property as the principal place of business, as this will accurately reflect the location where the business is being conducted or operated. If you need to use a different address for any reason, it is important to carefully consider the potential implications and to ensure that you can provide evidence to support your decision.
