ETUX/ETAL = proper notification?

[William W.]

I notice at the last tax deed sale that many properties may be listed as ‘John Smith ETUX (and wife)’ or ‘Jane Smith ETAL (and others)’. 

Let’s just say that John Smith is deceased, however his wife is still living, is the ETUX part of the newspaper listing considered sufficient notification to the wife? At the auction the wife’s name isn’t actually called out.
