(a) Inquire into the content, validity, invalidity, or completeness of the document, or the correctness of any information in the document.
(b) Provide continuing legal services to the depositor or to any beneficiary under the document. This subdivision does not affect the duty, if any, of the drafter of the document to provide continuing legal services to any person.
