What is the highest degree for law?

There isn't a single "highest" degree in law in the way there might be in other fields (like a PhD being the highest in many sciences). The highest *professional* degree in law is generally considered the Juris Doctor (J.D.).

While some lawyers may pursue further academic degrees *after* their J.D., such as an LLM (Master of Laws) in a specialized area or a SJD (Doctor of Juridical Science), these are generally considered specialized postgraduate degrees rather than higher than a J.D. in terms of professional standing. An SJD is more akin to a PhD in law, focused on original research and scholarship. A J.D. is the terminal degree for practicing law.
