Lindsay Lohan may lose her house.

A process server, who tacked the court papers in an envelope reading 'Important Information Enclosed' on the front gate of the home in Merrick, Long Island, confirmed to the New York Post newspaper the notice was due to a mortgage issue.

Lindsay, 26, reportedly left Los Angeles to return to her childhood home last month because she has no money left to continue renting her apartment in North Hollywood.

A source said: "Lindsay is being forced to live at home with Dina because she can't afford any other options at the moment.

"Lindsay is flat-out broke and can't even afford to rent a two-bedroom apartment in North Hollywood."

The 'Mean Girls' actress' mother, Dina, has long been embattled with Chase Bank over their attempts to foreclose the property.

Lindsay alleged that she gave her mum a $40,000 loan in October 2012 so she could pay back her debts and keep the house.

In a phone conversation with her father Michael Lohan, who recorded the call, she said: "I was like, 'Give me my money back! Give me my 40 grand back that I just gave you!' "

When asked why she gave her mother the money, Lindsay said: "Because she needs to keep her house."
