Yes, for my brother. I wish I could have done it earlier than I did, but when he called crying in fear for his life, that was the last straw. My brother never went back home to my dad. We picked up from their condo, and called the police. He went to live with my mom. After a nasty custody dispute. He was with us until it was final.
I had threatened one time before. But was "convinced" that that was a bad idea.
