I'm no attorney, but I've written about the subject a bit. The truth is that both of those guys are right. If you read both articles, you'll realize it isn't really a pro/con piece. The first 90% of asset protection is easy, cheap, and effective. What is that?
1) Get a pre-nup or better yet stay married. You are far more likely to lose your shirt to your spouse than to your patient.
2) Insure against catastrophe, especially liability. That means malpractice and a big personal umbrella policy.
3) Figure out what is protected in your state. Tort law is all state specific. But you may find that your state protects a significant chunk of your home equity, retirements accounts, annuities, and cash value insurance. For most docs, the best way to protect their money from creditors is also the best way to have a great retirement (max out the 401(k).)
4) Title your home properly. The phrase you want is tenants by the entirety. That way a suit against you can't take the house away since your spouse owns the whole thing also.
5) Exotic asset protection steps (foreign trusts, family limited partnerships etc) probably aren't necessary.
Seriously, that's 90% of asset protection.
