As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
 
According to the Hanafi school of thought, divorce issued in the state of intoxication is valid. In the enquired case, your friend’s mother is correct. The divorce issued is Talaaq-e- Mughallazah( a permanently irrevocable divorce). Your friend’s parents cannot live as husband and wife.
And Allah Ta’āla Knows Best
