Lindsay Lohan Bailed Her Mom Out of Foreclosure

Lindsay Lohan was telling the truth when she said her mom was on the verge of losing her house ...and Dina Lohan is not out of the woods yet ... TMZ has learned.

According to court docs obtained by TMZ ... JPMorgan Chase Bank filed documents in 2010 to foreclose on Dina's Long Island home because she had fallen behind on payments.

Now here's where it gets interesting ...The bank and Dina cut some sort of deal in which mama Lohan agreed to a new payment agreement that would prevent her home from going on the auction block.

Sources close to Lindsay tell us ... Dina didn't ante up on her own -- she got money from Lindsay to make the payments.

We're told Lindsay made payments that helped Dina dig out of the hole, but recently she fell behind again and Lindsay had to give her MORE bailout money -- $40,000. And that's the 40 grand that Lindsay and her mom were arguing over when things erupted in the limo early Wednesday.

One final thing. We're told Dina withdrew lots of other money from the Bank of Lindsay, including money to help pay for her kid brother's tuition.
