I called this office, and they said they would call me back soon. Two hours later, a "lawyer" called me back. I asked the question: "What documents can help in court to deregister a citizen of the Russian Federation from the property owner?" The response was, "You shouldn't register anyone!!!" I replied, "That's not a legal answer, but..." (I wanted to say "civic"), but I was interrupted with an indignant voice: "Are YOU going to teach me..." I hung up.
Is this professional? No. It's basic ethics.
I wrote a review on their website, and an hour has passed, and they are silent. They didn't even apologize. And these are supposed to be fair lawyers. Yeah... How are they going to defend anyone?
