Re: Outyard agreement
Unless money or something else of comparable value is being exchanged (and a couple of jars of "courtesy" honey won't suffice), any contract will be unenforceable.
If you can't trust the landowner based on a handshake, your hives are at risk no matter how much paper is signed and you should find another location.
As the landowner, if a beek asked me to be allowed to place hives on my land, I would view it as doing a favor, and if the beek then showed up with contract for me to sign, I would be insulted and tell him to find a new place for his bees.
(6th year, 10 hives, Zone 5b, 5506')
