N.C. Gen. Stat. § 35A-1267

Every guardian may charge in his annual account all reasonable disbursements and expenses; and if it appear that he has really and bona fide disbursed more in one year than the profits of the ward's estate, for his education and maintenance, the guardian shall be allowed and paid for the same out of the profits of the estate in any other year; but such disbursements must, in all cases, be suitable to the degree and circumstances of the estate of the ward.
