Yes it is strange. I felt the article also showed how simply getting a lawyer might not work out for you either.

You have to pay attention, had anyone been paying attention either at the legalzoom review/selection, lawyer selection, lawyer review or combination of both at all they might have been fine.

Having one lawyer all the way through is nice but that rarely happens in reality probably. Somewhere someone has to pay attention, legalzoom usage or with a lawyer.

Mistakes can obviously be made at any level, the best advice from this is probably get multiple lawyers but I am sure that is what the law firm blog wants you to do.
