While a lot of people are still in shock over the sudden demise of soul singer George Michael due to a heart attack last Christmas Day, another troubling account is already waiting in the sidelines. The music superstar born as Georgios Kyriacos Panayiotou has assets that need to be settled.

Questions are now emerging as to who will be inheriting his wealth. With a musical career that has spanned for around three decades, the former lead vocalist of the band group "Wham!" has been able to amass a fortune amounting to about $200 million.

There is a lot of finances to talk about considering that Michael has been able to garner global acclaim for classic hits like, "Wake Me Up Before You Go-go" and "Faith." The British singer has disposed more than a hundred million albums since his career took off in 1981 with close buddy Andrew Ridgeley.

The England-born artist has made a stunning milestone in 1985 when "Wham!" toured China. The group's entry into an Asian country is a first for a Western band.

After Ridgeley and Michael decided to head to opposing directions in 1986, the soul singer has unleashed a solo career that catapulted him on the Billboard Top 100 and the UK Top List. His song "Careless Whisper" has earned Michael a Grammy in 1988.

With considerable assets currently in the open, a legal battle is likely to ensue considering that the "Wham!" vocalist has no family of his own. In fact, he has never been actually married and has no children to speak about.

In the wake of his untimely death, it remains unclear if the Grammy-award winning artist has ever left a last will and testament. What is ultimately clear is the presence of his immediate family.

Following the singer's demise, a statement has been released, requesting that the family be given privacy during this difficult moment.

In line with the upcoming claims to George Michael's estate, a source has revealed that the British artist had a troubled relationship with his sister. Contact Music has divulged that the singer's sibling has been thrown out of her London apartment in 2004 since the former "Wham!" vocalist declined to support her whims. If there is any truth to the report, it is possible that such development will be included in the legal tussle for the award-winning artist's fortune.
