Divorce is a big deal for the world's wealthiest business tycoons, and spectacular settlements usually mean they have to pay their exes millions or billions in compensation for their long-awaited freedom.

In China it seems that most super-rich couples experience entrepreneurial hardships after marriage, but split up after creating their business empires.

Much of the time their break-up triggers fluctuations in the capital market, and turns them into life-long enemies amid various disputes and quarrels.

China.org.cn has compiled ten of the most expensive divorces encountered by China's super-rich:

   Wang Wei and Yang Lei   土豆網(wǎng)CEO 王微+楊蕾

Estimated settlement: 44.1 million yuan (US$7 million)

In June 2011, 39-year-old Wang Wei, CEO and founder of China's famous online video website Tudou, settled a divorce suit with his ex-wife Yang Lei by paying her 44.1 million yuan (US$7 million) in compensation. Under this condition, Yang agreed to give up her claim to a 38 percent stake in Tudou, which had disrupted the firm's plan for IPO on the US market for more than six months. Yet the firm still missed the best timing for going public. Its stock fell 38 percent within three days after its debut on August 17, 2011. Wang tied the knot with Yang, a renowned hostess at Shanghai TV, in August 2007, but filed for divorce one year later. Wang was said to have intimate relations with an American Chinese dancer, while Yang complained that Wang cared more for Tudou than for her. Later, the Chinese online video giant Youku officially "merged with" Tudou on August 20, 2012, with the latter withdrawing from the NASDAQ four days later.
