I'm surprised that you got that wrong, Jack, considering that you live in a community property state. Community property is a system in which both spouses own an interest in the community property. Unlike other states (equitable division states) in which marital interests are only taken into account when dividing up assets in a divorce, in a community property state the spouses have an actual property interest in the property during the marriage. Just because those things are titled solely in his name does not mean that they are his separate property. They may well be (and likely are) community property. And if they are community property, he does need her consent to sell them — so if the buyer is at all knowledgeable about community property laws in that state they won't touch it without her consent.
The post suggests the TRO is already in place, and thus he must follow the TRO. I think what you meant to say is that whether the TRO affects what he can do with the assets depends on what the TRO says about that. Very likely it does not address it.
What hasn't been served yet is the divorce complaint. And I agree with you and Budwad that the TRO would not stand in the way of getting him served with the complaint.
