CPAs absolutely have their license on the line and are required to validate and sign off on the returns that they prepare. They are liable for claims against the validity of the return. Tax attorneys are different; they don't validate returns, they handle legalities around tax lawsuits and IRS negotiations. I don't think a tax attorney would generally be involved with preparing a return, except maybe for reviewing ultra-wealthy clients for potential legal consequences.
