How does a QDRO work in spousal support?

An example may help: suppose that your ex-husband is ordered to pay you $500 a month in support. He fails to make these payments and soon is in arrears to the tune of $10,000. You would be able to obtain, under the laws of your state, a QDRO that would order the arrearage be satisfied by means of a garnishment of your ex-husband’s pension plan.
