Books for Teaching Legal English

I am been doing some research on the web about teaching English to people who work as lawyers in Taiwan. I am educated to master’s level in law and have been presented with an opportunity to teach a group of fifteen that work in a Taiwan legal firm. However, materials are scant. So far, I have unearthed:

amazon.com/International-Leg … 0521675170
amazon.com/Plain-English-Law … 1594601518

I am trying to get a general idea for any other suitable books. I imagine that business English course books might overlap with that I need, so it might make more sense to teach business and legal English together. Does anyone have any recommendations?
