Former high-flying lawyer Lloyd Rayney received taxpayer-funded legal aid for his murder trial last year after he was involved in the sale of more than $2 million of property in Perth's south.
Land title records indicate Mr Rayney reaped almost $1.9 million last year and in 2011 from selling five properties in Carlisle that he bought with his late wife Corryn.
The final sale was just weeks before his trial for her murder began in the Supreme Court last July.
Mr Rayney, who quit working as a barrister in December, is estimated to have spent about $2 million successfully fighting the allegation he killed his estranged wife on August 7, 2007.
Legal Aid director George Turnbull said yesterday Mr Rayney applied for funding six weeks into his three-month trial.
He was allowed the grant after satisfying strict criteria and on the condition Legal Aid could demand repayment at any time.
The assessment required that Mr Rayney had exhausted all available means of funding his own lawyer, Mr Turnbull said.
Land title records show Mr Rayney still owns the family's double-storey Como home.
A $776,000 mortgage was taken out in 2006 over the Como home and the Carlisle site with another $940,000 mortgage over only the Carlisle properties.
The mortgage remains over the Como property with an older mortgage for an unknown debt.
Records indicate Mr Rayney was a joint owner of two properties in Cloverdale and Willetton sold in 2009 and 2010 for a total of $931,000.
It is not known how Mr Rayney received or spent the money after the sales, including how much was used to pay the home mortgage.
His legal team included an interstate Queen's Counsel, a Perth barrister and a local solicitor. WA taxpayers also funded the State's prosecution bill of about $1.8 million.
The former prosecutor's acquittal came after five years of speculation after he was named by police as the "prime" and "only" suspect - a move that became a platform for Mr Rayney's defamation lawsuit against the police that is tipped to net him a multimillion-dollar payout, if successful.
Mr Turnbull said Legal Aid was aware of Mr Rayney's separate civil case during the assessment and was not involved in the matter.
His murder trial was told he had directed the proceeds of one of his wife's superannuation policies to their two children.
