Unclaimed Tax liens in Alabama

[Andrea P.]

By looking at the probate office database, I found several LLC company which aggressively (excess bid 10 times higher than tax due) purchase tax liens.
After a while those LLC go out of business and they not claim the tax deed after 3 years.
Furthermore they fail to pay taxes and therefore the land go to another tax sale.

As far as understand, the tax lien certificate owner has to claim the property, the tax deed is not issued automatically.

What happens in case of multiple tax lien certificates older than 3 years.
Does the tax lien certificates expire?
