I have no experience in this at all, but, I've often thought about buying in the future with a friend just because it may be the only way possible for me. Things I have thought about are; definitely get everything in writing in a binding contract, try to evenly split the property into huntable sections for amount of co-owners present and rotate those areas between eachother each year (you hunt that section this year and are responsible for all plots in it, and I'll stay in this section), have an age limit of bucks being harvested (actually send in teeth to be aged and have a penalty for harvesting something too young), have a max amount of deer that can be harvested each year, if big enough have a set-aside sanctuary that no-one enters unless tracking a wounded deer or shed hunting, set a certain # of guests per year (can be family or friend, keep in mind max amount of deer harvested) .... I think following steps like that would mitigate several problems, however, I would still be afraid of a partner backing out. Maybe have in the contract that if they want to back out, they first have to find someone else to take over their portion and new owner has to sign and abide by all previous rules set forth.. Then I guess you would only have to worry about them going through a bankruptcy. I'm sure it sounds a lot easier than it is. Like I said, I have no experience in co-owning anything with a friend.
