When the feds seize an asset they general do it via administrative forfeiture, which generally only requires probably cause. Once they seize it, the owner has 60 days to file a claim. If no claim is filed, the government keeps the asset.

If a claim is filed, the government can either pursue civil or criminal forfeiture. In the case of civil forfeiture there is a right to a trial by jury.

However, this isn't automatic. The person has to either have the legal knowledge to know how to file a claim, or they need a lawyer. In many cases no claim is filed because the legal fees necessary to recover the asset will be greater than the value of the asset.

Basically if the government sizes a few grand in cash, it will cost you too much to recover it to make it worth it. Also if you're not legally sophisticated, or too poor to pay a lawyer (and can't find free legal help), you're not going to get your money back.
