Support of Ward Having Husband Living

If a husband is unable to provide suitably for the support and maintenance of a wife over whose estate a guardian has been appointed by reason of her incompetency, the expense of providing such support or maintenance may, to the extent necessary, be charged against and defrayed out of such estate, as directed by the court or as approved by the court in settling the accounts of the guardian; for this purpose the guardian may sell or mortgage any of her property as hereinafter provided.
