Where in the State Code would I find the citation for "its an unauthorized practice of law for a Bank to close a real estate loan without an attorney present?

I've never tried to find it before, but see if this helps? http://www.scstatehouse.gov/code/t40c005.php

One other case source.

“The preparation of legal documents constitutes the practice of law when such preparation involves the giving of advice, consultation, explanation, or recommendations on matters of law. Even the preparation of standard forms that require no creative drafting may constitute the practice of law if one acts as more than a mere scrivener… We construe the role of ‘scrivener’ in this context to mean someone who does nothing more than record verbatim what the decedent says.”

Matter of Easler, 272 S.E.2d 32 (S.C. 1980)
