A judge in Suffolk County, New York issued the warrant on Thursday...
Kristi Kaufmann sued the Lohan patriarch in 2008 and won an uncontested judgment because Michael never opposed the baby claim, reports TMZ.com.
Michael Lohan insists he was unaware of the warrant and believes it is because he was a day late making his second child support payment to Kaufmann - and he's adamant once he makes the installment the warrant will be withdrawn.
