I have heard of title theft but I imagine it is more prominent is areas where an attorney is not required to process the sale of a house. Some states allow "title companies" to handle this process.
I'm not well versed, just passing along what I've heard from people over the years.
I have always heard the best way to make sure your title can't be stolen is to have a loan against the house so that a bank is involved. As long as a bank is involved, there are numerous additional hoops for something like that.
