Is this legal / ethical?
Yes. Citation verification against public court records is standard practice. Same check the judge’s clerk will run — you’re just running it first.
How fast?
Under 5 minutes for a typical brief. Longer for briefs over 50 citations.
What if opposing counsel’s cites are all real?
Then you saved 5 minutes and $49 versus doing it manually, and you file with confidence.
