Hi mick and welcome to the forum. Glad you are finding the site useful.
As one of the forum experts, and an IP also in general practice, I usually apply the number of outstanding contributions, and then discount for my fees in years which will no longer feature in the IVA. So in your case, I would probably ask the creditors for three years fees - the third to cover the cost of variation and closure.
Your IP may not necessarily need to contact the person who is giving you the money, but they will need to be certain that it is available and payable. In circumstances like this, I like to see the money in my client account as this brings certainty to the proposed variation and shows goodwill on your part. The money can always be returned if creditors turn down the offer.
There is no set time-period for proposing a variation, so you will beed to discuss this with your own IP.
Hope this helps.
