A "vindictive and spiteful" mother who filled in false paperwork to stop her ex-husband attending their son's cremation has been jailed for four months.
Cathleen Hackney was convicted of two charges under the 1902 Cremations Act last month after jurors heard that no one attended the funeral of Paul Moreland.
The offences of signing a false certificate and making a false representation with a view to procuring the burning of human remains meant Mr Moreland's father, Paul Barber, was unaware that his son's funeral was taking place.
Hackney, of Park View Close, Blurton, Stoke-on-Trent, remained composed in the dock at the city's Crown Court as she was jailed by Judge David Fletcher.
The judge, who also ordered Hackney to pay Mr Barber £5,000 in compensation, said the breaches of the Cremations Act had led to Mr Moreland's relatives being "kept in the dark" about his funeral in 2010.
Judge Fletcher told Hackney: "I have no doubt that this is a case where your actions were intended to cause harm specifically to Mr Barber. You willingly violated the criminal law to achieve that aim."
Adding that Mr Barber had suffered psychological distress, the judge told his ex-wife: "It's an old-fashioned word, but your behaviour was wicked."
