Criminal Law Questions? Ask a Criminal Lawyer.
If you are wondering whether or not you could be implicated, it's certainly possible, but if there's no evidence of your ever receiving any money from your housekeeper, then that would go a long way to convince law enforcement that you weren't involved. It would also make it difficult to convince a jury, which means that the DA will not be much interested in spending taxpayer money on further investigation or trial.
Hope this helps.

Oh. Depends on what the charge is. If this is an ongoing business, and a lot of money is changing hands, then it could be jail time, even for a first offense. If there's no evidence of an ongoing busness, then it could be diversion and no prosecution at all.
There's a lot of leeway, but without knowing the precise charges, it's impossible to do more than conjecture.
