When must a lawyer inform their client about matters requiring informed consent?

A lawyer must inform their client about matters requiring informed consent promptly because effective communication is fundamental to the attorney-client relationship and is essential for ensuring that the client can make informed decisions regarding their legal representation. The Model Rules of Professional Conduct mandate that attorneys provide clients with all relevant information in a timely manner, which includes disclosing potential conflicts of interest, risks involved in legal decisions, and any other significant factors that could affect the client's case or decisions.

This requirement is grounded in the principle that clients have the right to understand the implications of their legal choices and to participate meaningfully in the decision-making process. Prompt communication allows clients to consider their options and seek clarification when necessary, ensuring that they are truly informed. It empowers clients to give their informed consent rather than leaving them in the dark about crucial aspects of their case.

In contrast, waiting until the end of the case, a few days before significant decisions, or only providing information if the client asks would undermine the client's ability to engage effectively in their representation and could lead to misunderstandings or adverse outcomes.
