SafeGuard Guaranty, an insurance start-up based in North Carolina, recently released what it’s billing as the world's first divorce insurance product.

You can't buy the insurance and then collect if you divorce right away. The policy must mature first.
To help people determine whether they need the insurance, the company has a Divorce Cost Calculator and a Divorce Probability Calculator on its website.
No mention if it provides marriage counseling.
I'd caution anyone from marrying a person planning to buy this insurance.
