A retainer agreement primarily serves to outline the specific terms under which a lawyer will provide legal services to a client. This agreement details the scope of the legal services, the fees involved, billing practices, and obligations of both the attorney and the client. It establishes a clear understanding of the professional relationship and ensures that both parties are aware of their rights and responsibilities before commencing legal work.

In contrast, while the other options may relate to aspects of legal representation, they do not fulfill the primary function of a retainer agreement. For example, recording past payments is not the focus of this document; rather, it is about future commitments. Similarly, while clients do have obligations related to court appearances, this is not the essence of a retainer agreement. Finally, the documentation of a lawyer's professional credentials pertains to qualifications rather than the terms of engagement with a client. Thus, the correct choice highlights the foundational purpose of a retainer agreement in legal practice.
