We've done lots of development in the legal industry and IMO it has minor value maybe to a small lawfirm that thinks consulting is a term they want to pursue.
Law usually falls into a few big niches
Injury Law or PIA firms
Criminal
Divorce and Custody or family law
Business
Estate
Immigration
Bankruptcy
Corporate
Etc
Having managed many large budgets over the years for many firms I can honestly say not one client every asked about this term and not requested us to target it in either SEO or SEM (PPC)
Lawyers like their name .com
They like their geo and their niche
They like to see their phone ring
You might find low xxx from a speculator and high xxx from a firm but over that it would be a real lottery ticket sale if you get into xxxx range, not bad but no big value.
GOOD LUCK
