When default judgement is granted, how long does the defendant have to pay the money owed?

There is no time frame in which a defendant must pay a judgment and a judge will not and cannot force someone to pay a judgment.  Therefore there will be no order that the defendant will be violating.  A judgment is simply a piece of paper that says you are entitled to X dollars in damages, nothing more.  Once you obtain a judgment, that is when the real work begin.  Often times the easy part is getting the judgment, the hard part is collecting on the judgment.  There are many different methods to try to collect: bank garnishment, wage garnishment, writ of execution, etc.  All the methods are two things in common, they are slow and costly.  You may be able to recover those costs if you are able to collect, but you have to front those costs in the first place.
