She goes on to say that the accident left her husband disabled and they are in danger of losing it.The space rental is $590.Thoughts?

There are books on this strategy and would recommend reading up on it...The more assets you have the bigger target you will be, so if this is your first rental an LLC may not be fully essential, but I would recommend one to get familiar with how they work and how to protect yourself using one as your wealth grows.Every property has their own reasons why they might need to be in an LLC, whether it's someone tripping and falling on your front steps because a nail wasn't hammered in completely, and are now permanently disabled for the rest of their lives - to finding out the property you bought used to be a toxic dumping site and the State notifies you that you need to spend millions to remediate it.  

I could take the gate off or disable it and cover a portion with a stationary fence as a precaution.Or I could put a clause in the rental agreement to protect myself from any liability.

Jerry, I am definately NOT considering divorce (nor death, nor disability, nor getting locked up, nor exile, etc.).
