Lindsay Lohan's father Michael has been ordered to hand over additional child support payments to the actress' mother Dina. Michael Lohan and his ex-wife share four children - the Mean Girls actress and her three younger siblings Michael, Ali and Dakota - and Dina claims Lindsay's father has not been paying enough maintenance for their children. She alleges Michael owes $20,000 (£12,500) in back payments, and legal documents obtained by TMZ.com show he has been ordered to pay her $3,800 (£2,375). Michael argues that he has overpaid her already. According to the website's editors, Michael has until July (14) to pay the bill or a warrant will be issued for his arrest. This is not the first time the former couple has fought over money - last year (13), Michael had to hand over $30,000 (£18,750) after he failed to provide Dina with the agreed maintenance payments.
