Ms Hall, 65, gave her married name as Jerry Murdoch, petitioned for the permanent split in court papers filed in Los Angeles County Courts on Friday, according to DailyMail.com.
There is no mention of a prenuptial agreement in the divorce paperwork filed by her lawyers to end her marriage to 91-year-old Mr Murdoch, who has an estimated personal wealth of $7.68bn.
In her petition, Ms Hall states that she is not fully aware of the scope of Mr Murdoch’s assets and the papers say that her filing will be amended “when the information has been acertained.”
Hall also claims in the legal paperwork that she is unaware of the full extent of her ex-husband’s assets, with the documents stating that her divorce petition will be amended ‘when the information has been ascertained’.
“Petitioner is unaware of the full nature and extent of all separate property assets and debts, and will amend this Petition when the information has been ascertained,” the petition states.
Ms Hall’s lawyer, Ronald F Brot, states in the paperwork that the couple got married on 4 March 2016, but that the date of their separation is listed as “TBD.”
Mr Murdoch has 30 days to file a response via his own legal team.
The couple tied the knot at St Brides Church in London in March 2016. It has been reported that she filed for divorce just hours after Mr Murdoch emailed her as she waited in London for him to tell her that their marriage was over.
Ms Hall has been left “heartbroken” and “devastated” by the breakdown of her marriage, and blames Mr Murdoch’s adult children for the split, according to the news outlet.
