Reporting of unlisted shares

Without contribution how to hold share in Company

Share share holding of each shareholder under your mentioned company

1. Company may issue a share in Joint names as long the consideration is paid (whether by SH or any other person). The important consideration here is that who effectively holds the rights of the shares with respect to the transfer and other aspects such as receipt of dividend and voting rights. 
2. The above consideration will play a vital role in deciding who is the benefitial owener of such shares. 
3. With respect to reporting of such shares, ITR to my knowledge will not ask to report wealth or assets held by the assessee unless in certain cases. So if you willingly wanted to show the shares in the ITR (if the releavnt column is available ) then the above consideration can be applied to determine the beneficial owner of the shares. This is based on my own logic. If you wanted to have complete clarity on the above issue, it is better to approach a consultant or an expert. 
Please correct me if the above solution has an alternative view.
