The same ability that lawyers have – to be very adept at the core discipline of a domain (user experience design) but also the ability to learn the details of a particular area (the domain they are designing in). Good lawyers, like good designers, become experts in certain fields. Also, a background in journalism helps. Good UX designers ask lots of questions and need to be unbiased but still passionate.
