In many museums they document history. The history of the US was founded on laws and order of people to make the economy grow and to keep people safe in check. However laws have come a long way and needing a lawyer is now applicable for may reasons.
One of the most historic laws was attorneys that help with wills, trusts and estate planning.
One of the new law areas are for personal injury or localized law like (City + personal injury) or a more specific example would be a medical malpractice lawyer in Phoenix, or Personal Injury Attorney Phoenix
Another example and trending area for law now vs. in history is bankruptcy law like a “phoenix bankruptcy attorney/lawyer” which in the older days there weren’t bankruptcy attorneys because people really didn’t wrack up debt they couldn’t pay back on things like homes, cars, ect..
Lastly, a new type of law is for “wrongful death” and again relating this to popular Google searches of people searching their local area for an attorney to help them it would a something like “phoenix wrongful death attorney”
