Maybe not in your state? Certainly that is the case here. If my husband were to pass away tomorrow, his credit card debt would not die with him.
His estate would have to settle it. If he had no life insurance, the creditor could not come after you because you did not sign your name.
You are indirectly responsible in that regard, but you are not legally responsible.
Here is a blurb in Massachusetts from a Divorce Attorney--keep in mind it says the Judge "can" order you to pay--doesn't say the law will MAKE you pay. There can of course be mitigating factors.

Another state has a different law.
No judge can judge the binding contract of a creditor. Which is why some ex-spouses get stuck paying their own bills even if a judge decreed otherwise. So while a judge can say your husband MUST pay, VISA can still bother you for the credit card you obtained without an income. In my sister's divorce--she declared bankruptcy herself to avoid any misdeeds by her ex-post divorce. Of course these were joint cards. But again--while the courts can tell you one thing, the creditors do not care. They only care about their contract.
I have a friend whose husband (whom she was in the beginning stages of a divorce) die from injuries sustained in an accident. She did not sign any paperwork in the hospital. I think because they had a standing separation order--there was something to it, but this happened a few years back and my memory is sketchy....anyway, she did not sign any paperwork in the hospital.
He had no insurance and no life insurance. His week or so stay in ICU--had to be written off. They could not force her to pay as she didn't authorize anything. It was a blessing in disguise. She was a working mom (owns her own business), but that would have bankrupted her.
In Florida, judges can use discretion and distribute debts inequitably.
Virginia, where I live now--single debts are the responsibility of the spouse who acquires them. The state cannot force one spouse to pay the debt of the others. Joint debts have different rules, but are not subject to the new law mentioned in the OP--since joint debts are unaffected.
But the point is--it isn't true everywhere, and where it is true, VISA doesn't care what your judge says and will bug you if your spouse doesn't pay. Your lack of income will be an issue in that case and your credit negatively affected until it is remedied by the spouse.
