I am in a 50-50 partnership with my brother. The LLC was formed 4 years ago. He has never had any working or hands-on interest in the business and he is willing to bow out and give up his 50% of the business to me. I don't even know where to begin - can I just buy him out for $1.00 and then continue on with the same LLC as a sole owner? and keep my EIN? Or am I facing a much bigger ordeal? Money is not the issue - just procedure. (We are in Illinois).
