I have been give a 25% share of a new food business startup as a co-founder and working as the head chef. The business is due to open in a few weeks and pretty much everything has been set up though as of now I have had not been presented with anything in terms of a contract. Have been with the other founders ( 4 of us in total) to the bank to set up the account and my name is on that though I have had no other paperwork to sign or agreements drawn up between us.. Also I have not been required to invest any money. I get the nagging feeling that I could be getting screwed over but I need to know is there anything I should expect to have set in stone at this point, to ensure that the 25% is secured so that in the next 3-5 years I can't be told I have nothing? I know that as a part owner of a small business startup you shouldn't expect a wage but how do I secure my supposed stake in the company? Or is that covered simply by being registered on the accounts?
