Dear Querist, in relation to your question, my advice to you is:-
1. Partnership firm or any agreement regarding partnership, totally depends upon your agreement at the time of partnership.
2. Partnership agreement always have a clause saying about dissolution. If it says it is at will than you can serve a notice to the other partner and can dissolve that firm and all the things will be dissolved as per the capital you have invested.
3. As per your case, you have contributed 100% capital, so there is no need for sharing the capital.
4. Every firm has its own account, which needs to settled as per law before dissolution or at the time of dissolution, so you can contact to the other party for such settlement of accounts.
5. So, after serving notice of dissolution of firm you can clearly dissolve it and close your bank account as partnership firm
6. There is a point which you must bear in mind, as your partner has contributed in creating goodwill for your company, so he can claim it as a share.
Everything which I have suggested you is in accordance with the partnership Act, 1932 as amended upto date.
