He will be 67 in December. (he is going to appeal)
I would appeal turning 67, too!
My question is can she secure her alimony by attaching some kind of lien on any real property that we own together?
She absolutely can. This is why it's usually a very bad idea to own joint property of any type with someone who is divorced and/or has a judgment against them. I would suggest you speak with an attorney to see if there is any way you can now separate the joint property w/o the court seeing it as his hiding assets.
