What is the main focus of Rule 1.1 of the MRPC?

Rule 1.1 of the Model Rules of Professional Conduct is centered on the competence of a lawyer in representing a client. This rule mandates that lawyers possess the necessary legal knowledge, skill, thoroughness, and preparation reasonably necessary for the representation.

Competence is crucial for ensuring that lawyers provide effective and reliable legal services to clients. It encompasses understanding relevant laws and procedures, the ability to analyze legal issues, and the capacity to apply legal knowledge effectively to meet the clients' needs and protect their interests.

Although confidentiality, communication, and diligence are also important aspects of a lawyer's duties, they fall under different specific rules within the Model Rules. For instance, confidentiality is primarily addressed in Rule 1.6, communication in Rule 1.4, and diligence in Rule 1.3. Therefore, the core of Rule 1.1 is distinctively focused on the competence required by attorneys, making it the correct answer to the question.
