The court initially sentenced Chonsawat and Sakul to 12-month imprisonment and a fine of Bt9,000 each and Pratya to 10 months in jail and a fine of Bt8,000.
But the court lifted the imprisonment on ground that the three had confessed. They were put on probation for three years.
They were required to report themselves to probation officers for four times in the first year.
Pratya was also ordered to do community services for 24 hours.
Chonsawat used to be the mayor of Paknam Municipality. He was impeached on corruption charges.
His father was convicted in the Klong Dan waste water treatment corruption case. He fled the country reportedly to Cambodia's Poi Pet.
