Horror story: Yes, I have one.
A beginning beekeeper in our club was becoming very active, started with 5 hives that were donated by a retiring beekeeper. In a few months he had 12 hives from other donations. But, they were donated for his cause, which was educating children. He worked an agreement with a local business, a historical farm that was used for tourism, for to place his bees.
After one year, he was locked out and did not get his bees, tools or hives since the farm understood they were "donated" to them.
I don't know what the agreement said (i.e. % honey each received, what did proceeds get used for, etc), but he did say his mistake was not listing what was his vs donations to the farm. He lost a lot of tools, the bees, and his time. The farm hired another beekeeper to continue the work.
