How do I protect my investment property?

[Jason Neeland]

Hi, thank you in advance for reading.

I currently own an investment rental property that will be paid off in 8 years. I am the board president and 9 years ago amended the bylaws to be owner occupied. I have an ex-wife of many years who is trying to use a large debt of medical expenses for my son and is about to force me to sell this rental. Is there a way I can protect my investment? I can't sell it to family due to owner occupied and if I keep it, she will force me to sell or pull a home equity loan put to pay bills. 

Can I put it into an llc or add a 2nd person to title to help stop this?

Any help or advice would be a blessing.

Jason
