No; it is not true. Debts accumulated prior to marriage are separate property. If her assets are erroneously liened or wages garnished, you should be able to straighten the matter out with a simple letter or telephone call to the Taxpayer Advocate, nka the Executive Liaison at the FTB. If that does not work, you may have to consult with a tax attorney or CPA to gain more leverage; but, generally, that is not required.
Thus, you do not have to move out of the house.
One more thing...you did not state that you're married to this woman. You stated only that you've started living with her. California is not a common-law marriage state. That is, living together will never result in a common-law marriage in California.
It sounds to me like your not married. There is no common law marriage in CA so Community Property would never be an issue if you do not marry her. The only way that I can see they could possibly go after her is if you transfer assets to her to get them out of your own name in order to avoid collection.
There is no risk that the woman you are living with and/or her property can be used to satisfy the judgment against you. The community property laws of California have no application to unmarried persons. In addition, California does not recognize "common law marriage" whereby a man and a woman (or two same-sex people) are deemed to be marred after cohabiting for a specified length of time (usually years) and holding themselves out to the public as spouses.
If you decide to get married down the road, you and your girlfriend would be well advised to enter into a separate property agreement, to file separate income tax returns, and to ensure that you keep all of your funds and assets separate. You would be well advised to consult a family law attorney experienced at drafting such documents.
