Sylvester Stallone is firing back at his estranged wife, Jennifer Flavin, by denying that he's hiding any of their marital property ... but wholly agreeing the marriage is dunzo.
The actor filed a response to Flavin's divorce petition in Palm Beach County, FL -- which clearly states Sly has NOT engaged in the intentional dissipation, depletion and/or waste of marital assets ... this, according to PEOPLE, which obtained the docs.
It doesn't get more specific beyond that -- neither did Flavin, BTW -- but his attorneys make crystal clear that SS is not doing anything that could be labeled as moving/hiding assets.
