confused on WI death of tenant

[Kelly G.]

When a tenant dies (Milw, month-month), and has no $$ other than soc sec., is 28 day notice to the landlord really necessary?  My cousin is dying of cancer and the family is confused about how to handle notice to the landlord.  The statutes seem to indicate 60 days notice, but there would be no $$ to pay the rent as Soc Sec would terminate payments immediately.  The statutes also indicate 28 day standard notice. But all of this seems irrelevant if tenant has no $$.  I do see that the landlord cannot demand rent of tenant's family.  Perhaps I'm being overly cautious, just trying to give 'peace of mind' and a clear answer to my Aunt/family.  Aug rent was paid.  She will not survive till Sept.  landlord/tenant lawyer ref also appreciated - just in case. 

Thanks
