Hi lana
An iva is an 'individual' voluntary arrangement, so the amount paid back should be an affordable amount and as much as you can affford, payments obviously vary from person to person.
It includes all unseccured debts, and the payment will be based on the amount of disposable income you have left after paying all secured credit (ie mortgage, secured loans) and bills.
Have you completed an income and expenditure form as this is essential in working out your left over amount.
I am not an expert but am in an iva myself and would stress the importance of having a realistic i&e as it is for 60 months and needs to be affordable or will almost certainly fail over time.
Why not have a look on
www.iva.com at some reviews of iva providers and contact another one for advice on your specific situation. I took advice from 2 companies before deciding on my iva as felt it was so important to have confidence in the company you are dealing with as it is a long time and needs to be correct from the start.
Sorry if I am rambling but it is late (or is that early[:0]) and I am tired but can't sleep.
This forum is also a great place for getting professional advice and also support and advice from people in the same position.
It may help to post more information on your situation;
ie are you a homeowner?
what is your disposable income?
Good luck
