None of the above.
I am more concerned if the court can put a community lien based on the seperate property that is no longer available. I have to come up wth a defense for this.
If my (1) is incorrect, then more explanation is definitely needed.
If instead (1) is true, then I read your situation as being about a creditor (your ex) attempting to collect on a debt (unpaid spousal support), in which case the distinction between community property and separate property isn't relevant because both your separate property and your share of the community property belong to the debtor (you) and are therefore subject to collection efforts unless specifically exempted by law (e.g. your homestead).
If your spousal support payments were calculated based on your supposed ability to pay out of your jury award, then you might want to explore whether you can request a modification due to your changed circumstances. You will almost certainly still owe all the payments that were due before you file for your modification. It's my understanding that modifications always apply to the future, not the past.
I googled "community lien in Texas" and nothing came up to suggest that this terminology has a special meaning in Texas law, so I don't have the knowledge to help you with that.
