Thats not quite what you post. If you moved stuff around before the debt was incurred there would be no problem.
If you moved stuff around after the debt was incurred you can run some risk that your motivations were to defeat the creditor --and the closer in time you make the more to some action filed by creditor the more it might smell and to move right at time of action against one of you sure invites flunking the smell test.
Now some moves may work-(examples only--confirm with your counsel as to specifics which might work in your fact pattern .) -for example
1.a transfer of real estate to spouse alone that is recorded may time out as being reversible after say 1 year as in theory the other side is on public notice of the transfer .
2. You use the assets to pay down existing bonafide debt --and not in tainted by being just ahead of claim.
2.1 You use the account assets to buy something that is harder to attach.
2.2 you encumber the account somehow with something that is ahead of the other issue as to priority
3. At least in my state a significant gift to child in a UTMA would not be reversible against child.
4. As an aside if 'I" had a problem but my spouse cleaned out 95% of the joint account (ignoring tax issues) so as to fund a 529 plan for a child or grandchild in an amount that was reasonable to do-it might be hard to unwrap that one.
Note--the more likley you"know" the old debt has heated up and the more your move can be tied to same the more it looks like you have dirty hands.
How stale is the debt--is it beyond the statutue of limitations? That may be a good defense, if so..
