I think they just put anything to get your business! I would be dubious about the claims of legal expertise as well if I didn’t know that they must have qualifications@Sbag, your comments about don't assume those who advertise they are experts actually are, reminded me of an experience I had. Having read the website of a respected expert, I asked about some particular assistance, noted on the website.
What I was interested in was dismissed as not relevant anymore. An out of date website can be misleading. At the very least, professionals should update their websites.
