1. Get a lawyer involved in representing you in the divorce. 2. take the LA papers to the lawyer for a consultation. If she was gited the interest, then under Texas law, it is her separate property and you don't get it. The nature of the distributions from the LLC should be looked at. If income from the LLC, I'd argue the income is community. If capital distributions, I'd argue separate.
I am not intending this to be legal advice, because I don't know the particulars of your situation. Call me if you would like to discuss this or other isues.
