CAN THE HUSBAND USE HIS WIFES INHERITANCE?
If the question is "Does a husband inherit from his wife?" then the answer is yes. Shariah has reserved a fixed share for the husband if wife dies and leaves behind wealth.
If the question is whether a husband is allowed to use the wealth of his wife than she inherited from someone then that is only allowed with the wife's permission. If the wife does not give permission to her husband to use her wealth then it is not permissible for the husband to use her wealth.
And Allah knows best.
