Wait a minute! Everyone is jumping to conclusions without considering two things. 1. If a lien had been recorded on Naveen's home, the misfiling could have occurred at the county recorder's office. 2. Tax liens do not not attach to a specific property, but to All properties in the county of filing, And to any future properties.
A lien attaches to all of your assets (such as property, securities, vehicles) and to future assets acquired during the duration of the lien. Liens on business also attach to accounts receivables.
The lien notice went to Naveen's address, because that was the last address of record. If the address were a PO Box it would not mean that the PO Building had a lien on it. Naveen should check with her county recorder just to be sure under whose name the lien was filed.
