You have stated a lot of "red herring" information without providing any meaningful facts. You may wish to meet with an attorney in person to clear up a lot of your confusion.
In spite of the fact that Nevada is a community property state, creditors can only collect debts from people whose names are on an account. Medical debts & debts for other necessities are the one exception to this rule.
Creditors collect by suing to obtain a court judgment. Except for the IRS & debt you owe to your own bank, most other creditors cannot freeze your bank account without a court order.
If a bank account is in joint names, a judgment creditor of either party can freeze the account & ultimately take 100% the money in the account. So I would suggest that you not have any joint bank accounts with your husband until this matter is resolved.
Hope this perspective helps!
If your husband was involved in a short sale of his former residence, he should have gotten an agreement from the lien holders to accept the sale in total satisfaction of the lien debts. Otherwise, it is not a true "short sale". You need to get more facts before you can decide what to do next.
