My business partner cheated me

1.Basically my partner had the business idea and he did all of the work like, find the place to starting and running the business etc. All i did was invest all of the money ,my friend didn't invest any money . 2.Now the problem is when we went to register the company my business partner told the lawyer that he had the idea and i just did the invest and want to put me as a second part or the sleeping partner with two year contact.(before i invest i didnt write any partnership agreement). so i didn't agree to register and i didn't talk to that lawyer about it this. 3.But before i start invest the money i told my business partner the i want to be a active partner or right half of everything like profit to control of the business and he said YES but now he saying NO , 4.Now all i have is some voice recording of our conversion of him saying yes to my agreement with him before i gave him the money and ,i have paper work of i gave me the money. 5.So is there something i can do to get mine
