Is it permissible for a wife to give her children's surplus clothes to charities without her husband's knowledge?

The general rule is that a wife is not permitted to dispose of her husband's property without his permission. However, regarding clothes and used items that the children no longer need and are destined for destruction, the wife may dispose of them in a beneficial way, such as giving them as charity or gifts. If, however, they are still fit for use or sale, she may not dispose of them without her husband's knowledge and consent. Custom also plays a role in this matter.
