A sign of the times..
Stay well informed, make sure you are dealing with reputable professionals, don't be afraid to ask questions, and if it sounds suspicious, it probably is...
It is ok to ask to take away paperwork and have it seen by another professional, before you commit to sign.
If you are put under pressure to sign on the spot, be suspicious about it.
Just because the "so-called professional" is better dressed than you, has a nice car or a fancy office, don't be intimidated by those factors.
A successful professional wants your business but doesn't need it. Desperate cases lead to desperate measures, that may not be in your best interest.
Stand your ground.
