Voided Tax Sale - Alabama

[Tai Bhattad]

Can someone shed light on the void tax sale stipulations in Alabama... 

If the wrong name is called at the auction, someone ‘forgot’ to have the property assessed in their name, deceased owners prior to auction are reasons for a void tax sale. 

What happens in the event a property owner/occupant or heir intentionally leaves the deceased owner’s name as the assessed owner, or intentionally fail to assess the property to the correct name and decides not to pay the taxes... then property is auctioned and the sale is void. The heirs know it’s void based on above and claims void sale. How are taxes collected?

It seems a lot of void tax sales can & will happen. 
Is there more to the void tax sale deal. 
A few times I’ve called the county tax offices throughout Alabama regarding deceased owner’s delinquent tax properties and they have advised the sale is NOT void but this is challenged by the above stipulations. Any thoughts?
