Tan-Te Seng vs. Pangan

An attorney-client relationship is established upon professional consultation and the lawyer's acquiescence, regardless of a formal retainer agreement or payment of fees. A lawyer who represents adverse interests, willfully disregards succession laws to exclude rightful heirs, uses confidential client documents to initiate criminal proceedings, or employs abusive language in pleadings violates the Lawyer's Oath and multiple Canons of the CPR, warranting suspension and administrative sanctions.

Complainant Myriam Tan-Te Seng engaged respondent Atty. Dennis C. Pangan to facilitate the extrajudicial settlement of her deceased son Patrick's estate. During the drafting process, respondent excluded the complainant and her husband as heirs, misrepresented the age and legitimacy of Patrick's alleged daughter Patricia, and omitted corporate shares from the settlement. When disputes emerged, respondent married the widow April, represented her in mediation against the complainant, filed a falsification complaint using a document previously entrusted to him by the complainant, and described the complainant as a "devil" and "atat na atat" in a counter-affidavit, prompting the administrative complaints before the IBP.
