How to find owner of a property in uttar pradesh

As per the situation you've illustrated let me inform you that every shopkeeper needs to get a Trading Licence in order to practice his/her business. Basically, a "Trade License", is a certificate/ document that permits an individual or a group of individuals to carry on their businesses or trade activities in a particular municipal limit for the purpose of which it is issued.

The provision of a trade license is laid down by the State Government's in order to monitor as well as regulate various trade activities that are being carried out within a city limit.
Now, since the shop whose ownership details you're looking for is located in the state of Uttar Pradesh, you must know that the trade license or trading license is issued by the respective Municipal Corporations (authorities) of the State (Uttar Pradesh), to all the traders and establishments with an intention to monitor and regulate various trade activities that take place at the city level.

The regulations under Uttar Pradesh Shops and Commercial Establishments Act, 1962 apply to a shop or a commercial establishment located within the limits of municipal areas in the state of Uttar Pradesh. This Act has been enacted to consolidate and amend the law regulating the conditions of service of employees working in shops and in commercial establishments.

Every employer is required to make application for Registration or Renewal of his Shop or Commercial Establishment within 30 days of commencement of business. This Act is one of the mandatory requirements of all businesses which operate from an establishment or shop.

Therefore, in order to get the ownership details of the shop owner you must engage yourself to get in touch with the local City government offices that are responsible for issuing business licences (which you can do by searching online).

Once you have obtained the requisite government office address, you shall approach it along with an application in order to know the details of the shop owner stating the cause of doing so.
After, the application is submitted and is duly recieved by the authorities the requisite information you're looking for would be provided to you (i.e. the applicant).

Hope All This Helps!!!
