Actor-filmmaker Jude Law pays more than $250,000 a year in child support, reportz tmz.com.

The biggest share goes to his illegitimate daughter with Samantha Burke, and not the children he had with his former wife Sadie Frost.

Law and Burke had a brief fling in 2008.

According to an agreement between the duo, he had agreed to make child support payments for their daughter, Sophia, based on his income - $3.4 million in 2009 and $2.4 million in 2010.

As per legal documents, Law pays over $13,000 in monthly support to Frost. It means roughly $4,500 for each of their three kids.

But the daughter he had with Burke gets more than double that amount - $9,000 a month and it goes up every few years until she's 18.
