Should i invest my money in to my brother in-laws business? He needs cash to pay vendors and taxes. He needs a minimum of 300k. He has been struggling to do bad business partners. His business makes money. It is just a hard one to get financing for. No it’s not illegal.
It’s a terrible idea. You are a brother-in-law, not a bank. You’re hugely confusing and not understanding the relationship. Just because you are in a position to financially do this does not mean you should because the lines of your relationship will be hugely crossed. There is no long term positive outcome to fund him.
