Can multiple judgment collection methods be used at the same time?

Like anything there may be an exception, but more than likely yes...absolutely!

The party owed the debt is allowed to use any and all legal means to collect it, until the entire amount that is due them is received. Once there is no debt all actions must cease.

There is no requirement that only one method be used and in fact, if the debt allows it (most do), the amounts expended for each of the methods may increase the debt to be collected by each of the collection methods.

Conversely - someone under a judgment has no "right" to avoid paying it, using either one or any number of methods of avoidance, including ignoring legal demands. The obligation is to pay your debts, actually before they become judgments. Obviously the laws would rightfully generally be on the side of one owed an amount.

No. A judgment creditor can only execute the writ in one form, such as a wage garnishment or bank account levy. A single judgment cannot be used in multiple ways to collect the debt. This is one reason wage garnishment is the preferred method of creditors as the garnishment will stay in effect until the debt is paid.

If multiple creditors have obtained judgments against the debtor the judgments will be enforced according to their priority. Multiple judgments cannot be executed against a debtor at the same time. For example if several judgment holders place liens against a debtor's property the first lien holder gets paid first, and then the second and so on. The same holds true for wage garnishments or the levying of bank accounts.

Additionally the debtor has the legal right to protect exempted personal and real property from creditor attachment to the extent allowed by state and federal laws.
