Also, in the United States, PhD refers to a Doctor of Philosophy degree, which doesn't apply to the field of law. I'm not sure what the U.S. equivalent would be in this particular case, but there are a few possible law degrees in the U.S.
The Juris Doctor (JD) is the degree required to practice law. The Master of Laws is the next highest degree, while the Doctor of Judicial Science is the highest, and requires a dissertation. Without more context, I think the safest option would be to leave it as "doctoral degree."
