I wouldn't. I spent a bundle on an attorney when I went into PP (supposedly one of the best in the nation), and the changes they made in the contract that were finally agreed upon mutually were negligible. When I was a resident, everybody in my hospital (including non-pathology residents) always talked about getting a lawyer to review their contract so it seemed pretty boiler plate. Anyone can read a contract (lawyer or not), just like any pathologist can read a brain biopsy (neuropath trained or not). It's just a matter if you want an "expert" to review it. But the margin of error and complexity is far less in the average physician job contract than a biopsy. And a contract can be adequately evaluated by any physician with common sense. Two of the main things that are typically contested in a contract is termination conditions and non-compete/restrictive covenant. I would review those carefully, but my guess is this will be less stringent at an academic institution vs PP.
At the end of the day, even if you don't have an attorney review it, you're going to earn the same amount of money, have the same vacation, perks, benefits, etc. even if you didn't. The devil is in the detail and there may be other things in academic pathology contracts that others can recommend to look out for. I would talk to other junior faculty member in the dept. whom you know or are at least acquainted with and ask them if their contract was legit without any hangups that they regret. This could give you a heads up and you may not need any changes at all. But, save your money and don't get an attorney.
