Does the winner of a tax lien need to send notice to property owner ?

[William Smith]

Saw this on a post about tax liens in Lousiana?

"In addition, after the tax sale, the Tax Purchaser must provide an additional written notice, to all of the Notice Parties, of the fact that the property has been sold to him or her at the tax sale."

Does the winner of a certain property have to send notice? Thanks
