If property is titled solely in her name, then yes it may be seized and she would be wise to declare bankruptcy immediately to prevent this from happening, as federal bankruptcy law has protections for your home, your primary vehicle, and some other personal property.

If the property is jointly titled with her husband then there needs to be a subsequent Court hearing to determine how much each of the parties contributed to the joint property so the lien only attaches to that part which can be fairly attributed to the debtor. In this circumstance where the debtor is a stay-at-home mom and her husband earns 100% of the family's income, that hearing would likely assign 100% of the value of each asset to the husband. There are exceptions if it can be shown that she bought all or part of it with her own money, like if she had an inheritance or lottery winnings or something, but otherwise they will both just say that the husband is the sole equitable owner of any property and go about their lives.

Really as long as she keeps her husband happy and avoids a divorce, she has no worries whatsoever about this debt, aside from maybe having to spend a few hours of her time appearing at those subsequent court enforcement hearings or possibly filing a quickie "no asset" bankruptcy.
