Tough Bounce - Tenant's Trampoline

[Deanna Boss]

So my tenants have a trampoline. I ignored it because it's -20 here and it's covered in ice and snow so figured I'd address it in the summer but then my insurance sent a notice that they were canceling the policy because of the trampoline unless I signed an exclusion. Long story short as I researched and talked I decided there is too much risk to me for the trampoline so told the tenants it has to go. They asked if they got their own insurance to cover it and I said yes but they also have to talk to an attorney to have something drawn up that makes them 100% responsible for anyone who uses it. Yes? No? Anyone else have a tale to tell?
