going through divorce my wife is on the deed to the house with a hyphenated last name but uses a different legal name can she take the house?

A spouse's claim to real property acquired during the marraige is not tied to the deed. She could be not on the deed at all, and if the house was purchased during the marraige, or even before, depending on circumstances, she would have a claim to an equitable distribution of the home equity. The question of whether the deed needs fixing is a separate one. If it's not accurate, as part of a divorce I'd suggest getting that cleaned up so the title is clear.
