According to Rule 1.4 of the ABA Model Rules, what must be ensured when representing a client?

The correct answer, competent representation, is central to a lawyer's duties under Rule 1.4 of the ABA Model Rules of Professional Conduct. This rule emphasizes the lawyer's obligation to provide services competently and diligently while maintaining a standard of quality in their work. Competency involves possessing the legal knowledge, skill, thoroughness, and preparation reasonably necessary for the representation.

Rule 1.4 also highlights the importance of communication and responsiveness in the attorney-client relationship. A lawyer must keep the client reasonably informed about the status of their case and promptly respond to the client's requests for information. While aspects like affordability, speed of resolution, and a thorough consultation may play roles in the client-lawyer relationship, the overarching principle outlined in Rule 1.4 is that the lawyer must provide competent representation to effectively advocate for the client's interests and meet legal standards.
