Partners
I had a flying buddy as a 50/50 partner in my -6. we bought it together already built. The partnership went along great, until one day, he really understood the limited insurance we can get on the expermentals (100,000 per pax seat only). Knowing how little 100,000 is in a "claim". He started putting limits on who we took flying ie:family or known RV buddies.....people that may have known the risk. Well, eventually it lead to me buying him out of the partnership. He was bothered by the exposure "I" would be exposing him to as a half owner and vice versa. He bought a 182...for family flying.
If you look too close and think about it too much.....you won't fly at all.
but better to know what you are getting into before you enter a partnership.
I don't really like lawyers, they are a necessary evil in my book.
That said, partners are great, having someone to share flying with and motivate you to fly instead of work, etc etc....
Good Luck
