Gst Registration help needed

Hi I tried to register a GST before and it was rejected for the following reasons the consent letter is not authenticated and the property document is very old since property is jointly owned by me and my mother I uploaded the consent letter. I tried to reregister what are the documents I need to provide for the place of business eb bill was in my name and there is a mismatch in the address I havent paid property tax for few years can I use the old property tax bill for the registration or is there any other way?

Thanks in advance
