You have a SUPER firm and that is certainly the way it should be done. Are you in family law? True, our firm is small and the only one who ever proofs - if he wants to - is the attorney, but I don't know of any other firm we interract with that is very good about proofreading, based on the junk we see all the time. Gosh, it's awful.
I try to be very careful with my cases and jump on all documents when I get them. I know I drive my attorney nuts asking him questions trying to verify his interpretation of orders, his notes, etc.
I know he gets annoyed, but better that than a malpractice suit.
That lawyer is trying to sweep this well under the rug.
Small firm, general practice. We live in a rural area so it is mostly contract and wills/trusts. We do some family law as well.
The worst proofreading (or lack thereof) comes from Legal Aid.
He should be thrilled to have you doing that. It's in his best interest.
