The son of an Indonesian woman accused of ordering the murder of her Australian husband denies making a statement read in her defence.

John Ellis says the statement read in the trial on Wednesday, asking for a lenient sentence for his mother Noor Ellis, was forged.

The 23-year-old’s father Robert Ellis was found dead in in a Bali rice field in October last year.

The businessman’s wife of 25 years could face the death penalty for plotting with her two maids and five men to ambush and kill him in their Sanur villa.

A defence lawyer for Ellis, who is known also as Julaikah Noor Aini, read a statement purported to be from her eldest son.

“The witness begs that if his mother is truly involved in this matter of the death of his father, the sentence for his mother be lenient because his mother is the family’s backbone,” Ketut Suwiga Arya Dauh read.

“For money to go to school, for food and drink as well, the witness and his brother must ask their mother’s siblings.”

John Ellis says that’s not the statement he made to police on Christmas Day.

He has since learned of a statement with a forged signature, backdated to December 11, and his lawyers have filed a complaint it.

He now wants the false statement retracted from the evidence.

He says he doesn’t want to give any view about the sentence his mother deserves.

“We just want the justice system to do its thing,” he told AAP.

However Robert Ellis’ brother David Ellis, who attended court on Wednesday, didn’t hesitate to give an opinion.

“I’d be happy with death, I’ve got no qualms about it,” he told reporters outside court.

“At least a minimum of 20 years, you’d have to think anything less than that would not be justice.”

He also foreshadowed a bitter battle over the estate, which Ellis still has control over.

The family would “ruthlessly” pursue his brother’s fortune for his sons, David Ellis said.

Noor Ellis, who is due to be examined next week, has claimed she was a neglected wife, and became bitter when she was denied a divorce.

When asked at trial last week who ordered the hit, she replied “probably me”.

David Ellis trashed the claims she was neglected.

“She had full access to everything she wanted and she could’ve walked away,” he said.

“I never saw Noor with anything less than Rp 5 million ($500) on her and at least $10,000 worth of jewellery, never.”
