A bitter couple spent 10 years and more than $1million fighting each other in a divorce squabble that has bankrupted them both.

The couple split in 2006, started divorce proceedings in 2007 and did not settle the fight until last week – a dispute that was almost as long as their 12-year marriage.

In the marathon battle over how to split their estate, the Brisbane couple racked up debts that exceeded the value of their combined assets by a ‘significant margin’, reported The Herald Sun.

The wife, 53, borrowed $700,000 against the pair’s former family home to cover her legal costs, without the consent of her husband.

The husband, 67, spent $235,000 defending himself and had to raid his superannuation savings to cover his ballooning legal bill.

In a separate proceeding, the wife also spent six years going after her former husband and three business partners in the Queensland Supreme Court.

Justice Michael Kent told the Family Court in Brisbane the wife’s pursuit of ‘baseless claims’ in that case against her husband were the cause of the ‘extraordinary amount of costs’.
