London, Dec 13 (IANS) Lindsay Lohan's family feud is raging again as her parents fight over child support payments as the actress' mother has filed papers demanding her ex-husband pays up.

Dina Lohan has accused her ex-partner Michael of failing to hand over his monthly instalments for Lindsay's younger siblings Ali, 16, and Cody, 14, just months after the former couple settled a previous child support dispute in court, reports contactmusic.com.

The Lohan matriarch has lodged a complaint with the Child Support Collection Unit in Nassau County, New York, alleging Michael owes her more than $30,000.

Dina admits she's furious with her ex-husband for paying child support to a woman in Montana who won a default judgment against him because Michael never opposed her claims he fathered her young daughter.

"It's completely ridiculous. When I heard that he was paying for this child in Montana, I just had to fight for my kids... This child in Montana gets more than Ali and Cody (get). Lindsay is so upset and disgusted with him. Last year, I went to court on Christmas Eve, and here I am this Christmas, going back to court," said Dina.

Michael Lohan, however, retorted: "I never admitted it was my child. I'm paying to stay out of jail."
