Can an attorney be considered an expert in the drafting and advising of a contract?

In Du Pre v. Bogumill, 173 Cal.App.2d 406, at page 413, 343 P.2d 415, 420, the court stated, 'The defendant engaged the attorney to draft the documents and to advise them with reference to the transaction and plaintiff relied upon the representations of the attorney that the contract and the proceedings were proper and plaintiff conducted himself at all times as requested by the defendant. No bad motive and no intent to violate the law appears in anywise upon the part of the plaintiff.'
