Deputy Finance Minister Visut Srisuphan who signed the letter said he expected the letter would be received by Ms Yingluck within Thursday.
He said the letter, in essence, stated the wrongdoings committed by the ex-premier and the loss from the rice pledging scheme which were concluded by the ad hoc panel deliberating liability for wrongful acts.
Mr Visut said Ms Yingluck has 30 days to pay up the compensation as demanded otherwise authorities concerned will undertake administrative measures to deal with her.
Or if she disagrees with the demand for compensation, she can lodge a complaint with the Administrative Court within 90 days from the date she has received the letter of notification.
