A couple from William McIntyre, an author I have yet to read.
William McIntyre is a Scottish lawyer who has written about 10 books in his Best Defence series featuring a defence lawyer, Robbie Munro. He also has a standalone novel and some non-fiction to his name.
It's been a long while since I read any crime fiction with a legal lawyerly slant and McIntyre's books might be a good place to start, especially as they contain elements of humour.
From Fantastic Fiction
Based in Scotland and drawing on his thirty years as a criminal defence lawyer, there is a rich vein of dry-humour running through the series, which William describes as an antidote to crime fiction featuring maverick cops chasing a serial killers, emphasising that justice is not only about convicting the guilty, but also about acquitting the innocent.
The two I've managed to acquire are the seventh and eighth in his series. Ideally I would pick up the first and work my way forwards to these. Time and finances may dictate otherwise!
For reference the series opener is Relatively Guilty
Present Tense (2016)

Good News Bad News (2017)
Life's full of good news and bad news for defence lawyer Robbie Munro. The good news is he's in work, representing Antonia Brechin on a drugs charge. The bad news is that she's the granddaughter of notorious Sheriff Brechin.
Meanwhile, another of Robbie's clients, Ellen Fletcher, has won the lottery and asked Robbie to find her husband Freddy, who disappeared having swindled the evil Jake Turpie. Unfortunately, Jake's not willing to bury the hatchet - not unless it's in Freddy's head.
Robbie juggles cases and private life with his usual dexterity, but the more he tries to fix things the more trouble everyone's in.
"McIntyre's outstanding third mystery featuring Scottish defence counsel Robbie Munro perfectly blends humour and investigation...Readers will want to see a lot more of the endearing Robbie.""--Publishers Weekly *
