TSK · Numbers 30:15

But if her father overrules her when he hears about it, then none of her vows or her obligations which she has pledged for herself will stand. And the LORD will release her from it, because her father overruled her.

But if her husband clearly nullifies them when he hears them, then whatever she says by way of vows or obligations will not stand. Her husband has made them void, and the LORD will release her from them.
