COLUMBUS, Ohio (AP) - A lawsuit alleges Ohio has over collected millions of dollars in child support payments and doesn't provide parents with any way of knowing if they have paid too much.

The lawsuit filed Friday in the Ohio Court of Claims also alleges the state purposely over collects to boost federal incentives the state gets for processing child support payments.

The lawsuit alleges there are more than 114,000 child support cases where individuals have paid more than they're legally required, a figure that could be as high as $176 million over a 3-year period.

Ben Johnson, spokesman for the Ohio Department of Job and Family Services, declined comment.

Ohio processes about $1.7 billion in child support payments annually in a system serving about 1.2 million children.
