The 'secret ' teenage daughter of a late mining baron who successfully fought for $ 25 million from her father 's estate is now set to have her multi-million dollar inheritance challenged by her half sisters . Olivia Jacqueline Mead was left $ 3 million in a trust fund when her iron ore magnate father Michael Wright died in 2012 . The 19-year-old , who is the third and youngest of Mr Wright 's daughters , challenged his will in the West Australian Supreme Court in January claiming the amount left to her from her father 's estimated worth of $ 1 billion was insufficient . Scroll down for video . Olivia Jacqueline Mead may have her multi million dollar inheritance challenged after she successfully fought for $ 25 million in the West Australian Supreme Court from her iron ore magnate father Michael Wright 's estate . The court ruled last month that Ms Mead , the product of Mr Wright 's relationship with Elizabeth Anne Mead after he divorced three women , should be handed $ 25 million from his estate . But the matter is due to return to court this week after the Wright family signalled their intent to challenge the ruling . The $ 25 million was to be paid in a lump sum within 60 days of the February 26 judgement , but the Wright family has since sought clarity from the court about the drafting of orders - there 's a 21-day appeal period after those orders are drafted . The battle over Mr Wright 's estate made headlines earlier this year when lawyers pressed Ms Mead for details about why the $ 3 million sum was insufficient and what she expected she would need for the rest of her life . Mr Wright was estimated to be worth $ 1.5 billion when he died at 74 in 2012 . He was the son of Peter Wright , who co-founded Hancock Prospecting and Wright Prospecting with Lang Hancock .

The battle over Mr Wright 's estate made headlines earlier this year when lawyers pressed Ms Mead for details about why the $ 3 million sum was insufficient . Ms Mead told the court she needed a home five times the Perth median price ( $ 2.5 million ) , $ 10,000 each year for fashion accessories including Tiffany and Co sunglasses and $ 100,000 for a wedding when she ties the knot . Her initial list of claims also included an Audi A4 and a Toyota Tarago for when she has children , as well as a diamond-encrusted bass guitar worth $ 250,000 and a limited ­edition Kuhn Bosendorfer grand piano . In a summons filed in December 2012 , Ms Mead also claimed to have been left without adequate funds for her proper maintenance , support , education and advancement in life from her father 's estate in the bequeath to be held in trust until she was 30 . Her wish list amounted to about $ 20 million but Supreme Court Master Craig Sanderson ruled Ms Mead was 'in no sense ... spoilt by her father ' and deserved far more than she had been left . 'The deceased had a vast fortune and he was in the fortunate position of being able to provide for all of the parties who had a claim on his bounty , ' Master Sanderson said . Many in Perth had little idea Mr Wright had a fourth child until Ms Mead 's case went to trial . Mr Wright was estimated to be worth $ 1.5 billion when he died at 74 and was the son of Peter Wright , who co-founded Hancock Prospecting and Wright Prospecting with Lang Hancock - Gina Rinehart 's father .

The teenager 's half-sisters Leonie Baldock and Alexandra Burt , who both work within the family business , had been bequeathed $ 400 million . While Ms Mead had been included in his trust it was subject to onerous conditions , which meant that she might have received very little . She would have been deemed exempt from the funds if she 'had any association or involvement whatsoever to illegal drugs ' was convicted of any felony within the 10 years prior to his death , of if she had 'converted to Buddhism or Islam ' . The matter will return to court this week . Sorry we are not currently accepting comments on this article .
