Constantino vs. Aransazo, Jr.

An attorney-client relationship commences from the moment a client seeks a lawyer's advice upon a legal concern, and the lawyer's duty to preserve client confidences applies even where the parties maintain a personal friendship; consequently, a lawyer who discloses confidential information obtained during such consultation to the prejudice of his client, and subsequently adopts a position adverse to that client in the same litigation, violates Canons 15, 17, and 21 of the Code of Professional Responsibility.

Atty. Constantino and Atty. Aransazo were acquaintances from law school. In 2003, Atty. Constantino engaged Atty. Aransazo as co-counsel in a civil case involving the annulment of extrajudicial foreclosure proceedings over a mortgaged property. The case arose from a loan obtained by Hope Claire Aldaba from Eduardo Tongco, secured by a real estate mortgage. After Aldaba defaulted, Tongco assigned his rights under the mortgage to Attys. Constantino and Aransazo for P2,200,000.00. When Aldaba failed to redeem the property, the lawyers initiated foreclosure proceedings, which Aldaba sought to annul.

• Engagement as Co-Counsel: In March 2003, Atty. Constantino retained Atty. Aransazo to represent him in Civil Case No. 03-105994, an action for annulment of extrajudicial foreclosure proceedings involving a property mortgaged by Hope Claire Aldaba to Eduardo Tongco.
• The Deed of Assignment: Tongco executed a Deed of Assignment transferring his rights under the mortgage, promissory note, and special power of attorney to Attys. Constantino and Aransazo for P2,200,000.00. Atty. Constantino allegedly confided to Atty. Aransazo that he was cash-strapped and had only managed to source P1,100,000.00, requesting Atty. Aransazo to contribute the remaining half. Atty. Aransazo declined to provide funds but allegedly signed the Deed as co-assignee as an "accommodation" without contributing consideration.
• The Sworn Statement: On February 17, 2012, during pre-trial proceedings, Atty. Aransazo executed a sworn statement admitting that the Deed of Assignment was signed merely as an accommodation and without consideration from him, effectively claiming the deed was simulated. This statement was manifested by Aldaba's counsel and used to support a Motion to Admit Amended Complaint alleging the Deed was void for lack of consideration.
• Disbarment Complaint: Atty. Constantino filed the administrative complaint alleging Atty. Aransazo violated the attorney-client privilege by disclosing confidential communications regarding the circumstances of the Deed's execution, and by representing conflicting interests.

• Existence of Attorney-Client Relationship: Atty. Constantino maintained that he confided sensitive information regarding the Deed of Assignment to Atty. Aransazo in the course of seeking legal representation, establishing a privileged relationship protected by Canon 17 of the CPR.
• Breach of Confidentiality: Petitioner argued that Atty. Aransazo's sworn statement disclosed matters confided during their lawyer-client relationship in violation of Canons 17 and 21 of the CPR and Rule 138, Sections 20(e) and 27 of the Rules of Court.
• Conflict of Interest: Petitioner contended that by executing a statement supporting the nullity of the Deed of Assignment—which was the very document supporting their joint interest in the civil case—Atty. Aransazo represented conflicting interests and prejudiced Atty. Constantino's rights.

• No Attorney-Client Relationship: Atty. Aransazo countered that the information regarding the lack of consideration was disclosed due to their personal friendship before any lawyer-client relationship was formalized, and thus was not subject to privilege.
• Truth and Rectification: Respondent argued that he executed the sworn statement merely to rectify an error and reveal the truth regarding the Deed of Assignment's lack of consideration, consistent with his duties under the CPR.
• No Confidential Communication: Respondent maintained that because both lawyers knew the circumstances surrounding the Deed's execution, no confidential information existed to breach.

• Attorney-Client Relationship: Whether an attorney-client relationship existed between Atty. Constantino and Atty. Aransazo when the alleged confidential information was disclosed.
• Privileged Communication: Whether Atty. Aransazo violated the rule on privileged communication by executing the sworn statement revealing the circumstances of the Deed of Assignment's execution.
• Conflict of Interest: Whether Atty. Aransazo represented conflicting interests in violation of the CPR.

• Attorney-Client Relationship: An attorney-client relationship existed between the parties from the moment Atty. Constantino approached Atty. Aransazo to seek legal advice regarding the mortgage obligation and potential litigation, notwithstanding their prior personal friendship. The relationship imposes fiduciary duties regardless of whether the initial consultation was gratuitous.
• Privileged Communication: Atty. Aransazo violated Canon 21 of the CPR and Rule 138, Section 20(e) of the Rules of Court. The information regarding the Deed of Assignment's lack of consideration was revealed in confidence during the lawyer-client relationship and was permanently protected from disclosure. By reducing this information to writing in a sworn statement and divulging it to the adverse party, Atty. Aransazo breached his obligation to maintain inviolate the confidence reposed in him.
• Conflict of Interest: Atty. Aransazo represented conflicting interests in violation of Canon 15, Rule 15.03 of the CPR. As counsel for Atty. Constantino, he advocated the validity of the Deed of Assignment; however, his sworn statement necessarily refuted that validity and prejudiced Atty. Constantino's interest in the civil case. The intended testimony against his own client constituted a clear conflict.

• Commencement of Attorney-Client Relationship: A lawyer-client relationship begins from the moment a client seeks the lawyer's advice upon a legal concern, whether for consultation or representation, and the lawyer permits or acquiesces to the consultation. The existence of a personal relationship between the parties does not negate the professional relationship or its attendant duties.
• Attorney-Client Privilege (Wigmore Test): The privilege attaches where: (1) legal advice of any kind is sought; (2) from a professional legal adviser in his capacity as such; (3) the communications relate to that purpose; (4) made in confidence; (5) by the client; (6) at his instance permanently protected; (7) from disclosure by himself or the legal adviser; (8) except the protection be waived.
• Conflict of Interest: A conflict of interest exists where a lawyer represents inconsistent interests of two opposing parties, performs an act injuriously affecting his first client, or uses knowledge acquired from the first client against the latter. The prohibition ensures freedom of communication between lawyer and client based on trust and confidence.

• "A lawyer-client relationship begins from the moment a client seeks the lawyer's advice upon a legal concern. The seeking may be for consultation on transactions or other legal concerns, or for representation of the client in an actual case in the courts or other fora. From that moment on, the lawyer is bound to respect the relationship and to maintain the trust and confidence of his client."
• "Without a doubt, the contents of respondent's sworn statement contained information revealed to him in confidence by complainant during a lawyer-client relationship. By executing the sworn statement alone, respondent breached his obligation to maintain inviolate the confidence reposed on him and to preserve the secrets of complainant."
• "A conflict of interest exists where a lawyer represents inconsistent interests of two opposing parties, like when the lawyer performs an act that will injuriously affect his first client in any matter in which he represented him, or when the lawyer uses any knowledge he previously acquired from his first client against the latter."

• Diongzon v. Mirano, 793 Phil. 200 (2016): Controlling precedent defining conflict of interest and the fiduciary nature of the attorney-client relationship; followed in determining that Atty. Aransazo represented conflicting interests.
• Burbe v. Magulta, 432 Phil. 840 (2002): Controlling precedent regarding the commencement of attorney-client relationship; followed to establish that the relationship existed from the moment of consultation.
• Mercado v. Vitriolo, 498 Phil. 49 (2005): Cited for Dean Wigmore's eight-factor test for establishing attorney-client privilege.
• Hadluja v. Madianda, 553 Phil. 221 (2007): Cited regarding the purpose of the confidentiality rule to protect the client from breach of confidence and preserve the trust relation.

• Canon 17, Code of Professional Responsibility: A lawyer owes fidelity to the cause of his client and shall be mindful of the trust and confidence reposed in him.
• Canon 21, Code of Professional Responsibility: A lawyer shall preserve the confidence and secrets of his client even after the attorney-client relation is terminated.
• Rule 21.01, Code of Professional Responsibility: Enumerates limited exceptions to the duty of confidentiality.
• Rule 21.02, Code of Professional Responsibility: Prohibits use of information acquired in the course of employment to the disadvantage of the client.
• Rule 15.03, Code of Professional Responsibility: Prohibits representation of conflicting interests except by written consent after full disclosure.
• Section 20(e), Rule 138, Rules of Court: Mandates attorneys to maintain inviolate the confidence and preserve the secrets of their clients.
