A client started an LLC in 2018. An Angel investor paid for his business Filing, website, website hosting, and other general expenses. The initial understanding was that he would be an equal partner, and get reimbursed for all his expenses. Only my client’s name appears on all business filings, bank account, etc. He (Angel) has been asked numerous times both orally and writing to submit receipts and invoices, but he has refused. Now, he says that he doesn’t want to pursue the relationship any further with my client, and the client should just keep everything for himself. My client wants to pay him back in full as originally agreed, and file all proper tax filings. What should he do? Should he make a goodwill estimate of the expenses and just write the investor a check? It is a real mess.
