WHAT DENT DID:

* The NSW woman poisoned her partner David Lawrence, 62, in 2015 with a toxic cocktail of drugs including morphine, valium and tramadol.

* The Crown alleged she murdered Mr Lawrence and faked his will to claim his $300,000 estate.

* A post-mortem examination revealed the toxic levels of morphine alone were enough to kill the 62-year-old.

WHAT THE JUDGE SAID:

* Justice Tim Stanley said Dent had shown no remorse or contrition and had exploited Mr Lawrence's love for her own financial benefit.

* "Ultimately you killed him for your own financial gain," the judge told her.

* "I am not in a position to make a finding as to whether you administered the fatal cocktail or you induced Mr Lawrence to do so, but it makes no difference to your culpability for his death.

* "Your actions demonstrate your determination to pursue the plan to enrich yourself through his murder."

WHAT THE LAWRENCE FAMILY SAID:

* Mr Lawrence's nephew Blake Lawrence said the family was pleased with the 25-year sentence which meant Dent was likely to spend the rest of her life behind bars.

* "She exploited David. He was a kind, loving, gentle person and she took advantage of that for her own greed," he said.

* "She's a callous, remorseless individual. We're glad to see her stay behind bars."

WHAT DENT ARGUES:

* Dent has launched an appeal describing her conviction as unsafe and unsatisfactory on the evidence at the trial.

* She claims the pair were "besotted" with each other, had planned to marry and Mr Lawrence had made arrangements for her to be taken care of after his death.

* Dent says the Crown had not properly discounted the possibility that Mr Lawrence's death was an accident.
