Hello, I am working with a partner to sell goods from US to Europe. My partner already had an established company and we decided to use its name to market our products and enjoy benefits of marketing as an established business. Now I need to be either added to his company which is an S-Corp but don't know how to make sure I won't be liable for the past operations of the company. Or I need to open my own company to go to a joint venture with his but I don't know what that may entail in terms of capital that needs to be put into the business because I read that both companies should equally invest. Any suggestions??
