Simon Cowell -- Lauren Silverman's Divorce Settlement Provides Simon Must Stay Away From Son, OR ELSE!

Simon Cowell's baby mama, Lauren Silverman, signed a divorce settlement agreement which has a shocking penalty -- if Simon goes near her 7-year-old son, she has to pay her ex a $50,000 PENALTY!

TMZ is privy to the unbelievable settlement agreement, which also provides that if Lauren violates the Simon stay-away clause 3 times, she loses all contact with her son, Adam, until a court deals with the violations.

The Simon stay-away clause only lasts until January, 2015. So presumably the kid can be around Simon in a year ... if he's still part of Lauren's life.

But the plot thickens. The settlement agreement also provides Andrew Silverman, Lauren's ex, cannot trash Simon to Adam and has a legal obligation to make sure no one else around him talks smack.

And there's a clause in the settlement that provides Lauren and Andrew both agree to prevent Adam from calling anyone other than them "mother" or "father." Translation: Simon is not your daddy.

Andrew agrees to pay Lauren $3k a month in child support ... a modest amount and it goes to what TMZ has been reporting ... that Simon will become the cash cow.

Finally, Lauren and Andrew agreed to change the cause of divorce from adultery to "broken down irretrievably."
