2 years ago I and my friend formed an LLC for an internet startup we set out to build. I agreed to a 50/50 split,he was in charge of managing the development and I agreed to invest about $6k to get the beta site built .This was supposed to take less then 6 months.. It's now been close to 2 years and nearly $20K and we're just getting close to our goal of getting this done. Over the past 2 years, my partner has made several unnecessary & insignificant changes and redesigns.He just racked up the bills and kept sending them my way till I took everything into my own hands. I have come to realize that my partner has little to no experience, knowledge or business acumen necessary to get this done. Since then his contribution has been nonexistent, refuses to put in any legwork etc. What can I do?
