Ummmm, I have some real issues with what you're doing.
Giving false details? There's a name for that and it isn't a nice one. If anyone gets a whiff of that you could end up with a fraud marker on your credit record - if you think debts can be a problem try getting credit once that pops up.
Once it's a court issue you have no choice but to tell them what they need to know. You really don't want to end up in a situation where the court gets grumpy with you. Attachment of earning orders are relatively rare in my experience, but again, if debtors think you're taking the mickey, or if the court does, you may find them deciding to go the extra mile in your case.
Lots of people on here deal with their debts legitimately, even if it stretches their wallets and nerves to the limit. I'm not especially pious, but I fear you're overstepping the mark, frankly.
Oh, and I'll tell you one other thing, from my distant past as a debt collector and tracer. The hardest people to find were the ones who had a genuine reason for vanishing; people who thought they could vanish and tried to cover their tracks were often a piece of cake to find. Do you want to explain to you mam that she must never discuss you with anyone in case it's a debt collector who's decided to come after you because he thinks you're taking the p***?
