@CalamityJane,
And that is exactly what I did in CA.
My father owned a cabin on five acres in Big Bear. Well he left half to his brother and half to me. I no longer wanted it and my uncle refused to buy me out. We were listed on the deed as joint tenants.
I contacted an estate-planning attorney and said it didn't matter, he said I could do what ever I wanted with my half of the property. When I told my uncle I was putting my half up for sale he quickly changed his mind and bought me out.
Perhaps he only bought me out because he knew I would make sure it cost him in legal fees if he didn’t.
He and I are not close at all, we haven't spoken in five years and I'm okay with that.
