Lindsay Lohan's mother claims her father Michael isn't paying for their son's education.

Dina Lohan has filed court papers claiming her ex-husband refuses to pay for Lindsay's 17-year-old brother Cody, who attends a Catholic school, and is appealing for him to start giving her money for the tuition fees.

According to TMZ, Dina, 51, says her and Michael, 54, were meant to split the $10,000-a-year tuition fees but Dina insists she has been paying for the school for the past three years and claims her former husband hasn't given her a penny.

However, the showbiz patriarch, who also has children Michael Jr. and Aliana with Dina, has dismissed the claims and told TMZ he already gave Dina $30,000 for the school and bought Cody a car.

He also insists he's given her $1,500 a month for the past two years and gave daughter Aliana $35,000 to pay the rent for her New York apartment.

Michael has also hit out at Dina for allegedly spending $10,000 on trips to visit her boyfriend in Texas.
