No they are not different (at least as far as the likely action following non-payment is concerned) except in the case of them being written off (see below).
Since April 2006 Magistrates (and judges in Crown Courts) have been making �collection orders� at the time they impose fines, costs or compensation. This means that further action for recovery of the debt can be taken without recourse to the Court. This action can include the use of bailiffs who may, if appropriate, seize goods (including vehicles) to recover the sum.
If this type of action fails the defaulter will be summonsed to appear before a fines enforcement court. Here, magistrates will enquire into the defendant�s means. They have a number of options open to them after doing this. They may issue an attachment to earnings order, a deduction from benefits order, or a distress warrant allowing bailiffs to seize goods.
If they believe there are insufficient funds to pay they may remit (i.e. write off) all or some of the fines, but they cannot remit costs or compensation.
Finally, if they decide that funds are available but there has been a wilful refusal to pay, then they may commit to prison, although this may be suspended to give the defendant an opportunity to pay. The length custody is set down by statute and depends upon the amount owed.
