Seattle Seahawks Star Chris Clemons' Ex -- He Gave Me a House ... And Then Kicked Me Out of It!

Seattle Seahawks sack machine Chris Clemons callously kicked his ex-wife out of his giant house after she drained her LIFE SAVINGS -- this according to new legal docs -- and now she's out for payback ... again.

As we first reported, Clemons and his ex Veranetta finalized their divorce last month and Chris agreed to fork over $500,000 and a Land Rover.

But Veranetta just filed new legal docs claiming Chris felt bad about the sudden split and wanted to give her more than just the settlement amount ... so he offered her his Georgia mansion as well.

Veranetta says she moved in on Chris' word -- before he paid her the $500,000 -- and spent every penny she had on other things, figuring she didn't have to worry about her living situation any longer.

Veranetta claims she then asked Chris to pay her $74,856 in attorneys' fees as well -- and for some reason, Chris flipped at the demand ... revoking the house gift and insisting Veranetta clear the premises.

We're told Chris paid Veranetta the original $500,000 settlement and she took off -- but now she's firing back ... demanding $82,687 in attorneys' fees.
