Hi Mitch,
Firstly, sorry to hear of the double bereavement in your family.
I've read your other posts with interest, and I get the impression that you want to keep hold of as much of this windfall (when it finally becomes available) as you can get away with, so that you can get your life back on track.
I don't blame you!!! So I'm going to play devil's advocate here:
Yes, you could settle up your IVA early, but your credit file is still shot for 6 Years, so talk of getting credit again (at sensible rates anyway), is unlikely in that time.
I also like the most sensible (and legally less controversial) suggestion that your parents could 'hold this in trust' for the duration of your IVA.
However, my suggestion if you want to get your hands on the money quickly:
1). Don't mention this potential windfall to your IP;
2). By all means propose a F&F (via your parents) based on what you would have originally had to pay (£6K, less your payments to date). If the creditors don't go for it, let the IVA run its course;
2). Regardless of the outcome of the above, and certainly in the interim: Ask your parents to open up a savings account in their name, but to which you have access (the card, PIN number, internet access etc); and
3). Only once you get you completion cert, can you / your parents safely transfer the money to your account (if they do so beforehand, your IP might smell a rat!!!). Prior to that, just use it for cash withdrawals, and purchases.
Regardless of when you get this money, or how much of it you get, you might find moving difficult with credit checks etc, so suggest you use parents as guarantors (if they agree of course).
Sorry if this throws a cat among the pigeons, but I can't be the only one who thinks like this!!!
Best of luck.
My opinions are just that: Based on my experience and being a self-employed IVA customer.
