I can’t answer specifically, but I knew a guy who owned a number of properties. Single family homes and some small apartment buildings. Each of them was held in their own LLC. It was a way to protect one assets from the others. In other words, if he had to give one to the bank at a loss, the bank couldn’t get hold of the other properties because each LLC was a separate legal entity. I suppose it could be done if the accounting was sloppy... but he was an accountant.
People are suspecting all these LLCs in Anna’s name are the Duggars way of moving property and money around in case Josh goes to jail and the feds try to seize any profits he made from the CP. I am being told the feds can still seize it but don’t know if it’s true.
