According to the documents, Headey asked her estranged hubby for her share of their 2011 tax refund, stating in a declaration that, after she married Loughran, she became pregnant with their first and only child, who's now 2, and was deemed not insurable due the pregnancy and was unable to work.

Because of that, the British actress says, they "burned through their savings" and "incurred a substantial amount of consumer debt to pay for our living expense during marriage."

She is currently asking for a $6,000 advance from her half of the 2011 tax refund and a hearing has been scheduled for April 26.
