"P" owns a proprietorship concern XYZ from past many years and is doing his business. Now he enters into partnership agreement with "S" and they form a partnership firm with same name XYZ in February 2017. P states that he has transferred all his assets and liabilities to the firm but that is not documented in the partnership agreement. Further the partnership agreement is not registered also. P and S hold 50:50 share in the partnership firm. The queries are as following:

1. Can a proprietorship and partnership have same name XYZ?

2. What are the consequences of non registration of partnership firm?

3. Although P says he has transferred his assets and liabilities but since they are not documented can we consider this deed valid?

4. Does transferring all assets and liabilities of proprietorship concern in partnership means dissolution of the Proprietorship concern (i.e. it cease to exist)??

5. Will the turnover of Proprietorship after its transfer / dissolution be treated as turnover of partnership from February 2017 legally?

If a proprietor is non existing tax payer and his turnover exceeds 20 lakhs , is it compulsory for gst registration , if yes then how he will get provisional id and password.

While checking, noticed difference of amounts in Purchase register and Purchase account in Tally. Why that difference.?

I have a dealer who has taken registration under MVAT after 25th May 2016.He has taken VAT registration through an Advocate who has put his email Id as the registered email Id.and that consultant is not sharing any details with the client.
In the recent scenario,if u have taken registration after 25th may,2016 then u have to send email to resetpassword@mahavat.gov.in from your registered email Id mentioning all the details,in this case i don't have registered email Id and help desk persons are saying that we can send password only on registered email only.
Please tell me the solution for the above?
