"Growing up as a family my mum, dad and I were completely inseparable," she wrote.
"We would spend all of our spare time together and family was everything to us. The love we had for each other was unexplainable, and everyone in our lives saw it."
Sarah, Karen and Borce's only daughter, went on to defend her father stressing she had "never witnessed any form of violence between my mum and dad".
"My dad has not had any prior convictions or issues with the law...my dad has experienced job loss, a loss of respect within the community and the loss of close long-term friendships."
She highlighted how difficult the intense media scrutiny has been on herself and her father, and expressed a wish to "one day experience" the type of marriage her parents had herself.
Ms Ristevski also said she has visited her father every week since his arrest in December 2017 and speaks to him over the phone daily.
The character reference, described by Justice Christopher Beale as "glowing", comes after Borce Ristevski's estranged son Anthony Rickard came forward with shocking claims about how his father murdered his step-mother.

Anthony Rickard - Ristevski's troubled son from a previous relationship - told 7 News he believes Borce choked his wife to death following a heated argument about money in which Karen threatened to "destroy him".
"I think he acted - not on purpose - but he did obviously choke her. She's a tiny woman. Just a little squeeze would've been enough," he said.
Mr Rickard claimed Karen was preparing to leave her husband, which he said would have "left him in a big hole financially" as the Ristevski family home is in her name.
Karen Ristevski, 47, vanished from the family home in Avondale Heights just outside Melbourne in June 2016.
Her body was discovered in a shallow grave in the Macedon Ranges over eight months later, too badly decomposed to determine a conclusive cause of death.
A funeral service was held in on March 6 2017 with Mr Ristevski acting as pallbearer.
Because of his manslaughter plea, Ristevski will avoid a life sentence and instead faces a maximum of 20 years' imprisonment for his wife's death.
