There are some nets, but they aren't as official. The lawyer version of a Doctor's prescription pad is the ability to send threatening letters on law firm letterhead. Lawyers are also afforded privilege's in jails and prisons, things like non-monitored phone calls, that aren't made available to non-lawyers.
but there's no safety net for things that are outside the justice system (e.g., "is this a fair contract?") or things the aren't in the justice system yet (e.g., "am i allowed to cut down my neighbor's tree if it blocks my view?")
Luckily doctoring has the safeguard that you will need a professional to get drugs/treatments, but there isn't as much of a safety net for lawyering
