Code of Professional Responsibility and Accountability (CPRA)
Section 3. Lawyer-client relationship. - A lawyer-client relationship is of the highest fiduciary character. As a trust relation, it is essential that the engagement is founded on the confidence reposed by the client on the lawyer. Therefore, a lawyer-client relationship shall arise when the client consciously, voluntarily and in good faith vests a lawyer with the client's confidence for the purpose of rendering legal services such as providing legal advice or representation, and the lawyer, whether expressly or impliedly, agrees to render such services.
