Most of the advice given so far is fairly accurate...let me sum it up. You have 2 options:
1. Pay the debt voluntarily if you can---sooner the better as time is not on your side
2. Have your assets taken to satisfy the debt. Either way you will end up paying the 80K plus accrued interest and costs. Post judgment collection includes liens on real property, siezures of personal property, wage garnishments, bank/brokerage account attachments, life insurance, liens on any lawsuit or insurance recoveries, and at least annual debtors examinations. The judgment will appear on your credit and may impact your ability to obtain employment, insurance, leases for cars or apartments etc.
You have some exemptions to the above, but you must claim them and they are subject or the judgment creditors potentiual objections.
Do not try to transfer or convey assets or try to hide them. It won't work and moreover exposes you to claims of fraudulent transfer.
The "matress" idea expressed by one respondent is risky. If the JC determines you've been secreting cash, you could have additional civil and criminal exposure.
