Mushroom killer Erin Patterson's remaining wealth may become the subject of the next legal battle involving the jailed triple-murderer.

On Monday, Patterson, 50, was sentenced to life imprisonment over the murders of Don and Gail Patterson and Gail's sister, Heather Wilkinson, and sentenced to 25 years for the attempted murder of Ian Wilkinson.

The sentence, which comes with a non-parole period of 33 years, has been described as a win for the triple-murderer, given she may one day walk free.

Less clear is what will be left of her once-lucrative estate when an 83-year-old Patterson becomes eligible for parole.

Having chipped away at her sizeable property holdings to mount a top-tier legal defence, her diminished estate is expected to become the subject of victim compensation requests.
