An LLC maybe pierced by a plaintiff attorney, but they have to do the extra work to get the ruling. Also, gives the defendant (owner) an appeal if they desire. Unless it is a huge claim or the attorney has no other work, makes it less appealing for lawyers and much more likely to settle.
The above is just an example of why I use LLC on all my properties. If you should get a judgment against you and you aren't using an LLC, etc, the plaintiff can lien your personal assets!! I just keep minimal money in my LLC accounts. Of course all this is assuming insurance coverage is not involved for some reason.
There is also a good deal of anonymity when using any sort of legal structure. Pretty easy to move ownership around.
This year, I had a tree from one of my properties fall on a neighbors car. Clearly an AOG. Neighbor would not file on his insurance, hauled ME to small claims court. Property titled in LLC, I produced a copy of the deed in court. Judge dismissed suit, told the neighbor to re-file. (Neighbor had the cost of filing,serving process and a lost day of work) I never heard another word.
In my experience, I title everything in an LLC (single member in my case), insurance on all properties and umbrella policy. Not really over the top, just the world we live in these days.
