Okla. Stat. tit. 58, § 58-523: Representative shall not profit or lose

He shall not make profit by the increase, nor suffer loss by the

decrease or destruction, without his fault, of any part of the

estate. He must account for the excess when he sells any part of

the estate for more than the appraisement, and if any part he sold

for less than the appraisement, he is not responsible for the loss,

if the sale has been justly made.
