When does duty of care start and stop having trouble paying iva cant really afford it been in 3 years keeps going up due to increased earnings ip dosent seem to want to help
There are indeed guidelines for expenditure that an IP would normally follow.
Each year you should have an Income and expenditure review, has this been happening ?
Does the expenditure list all of categories that you spend out on ?
Are the amounts realistic ?
One thing you may want to try if your not doing it already is budgeting. I for instance have separate bank accounts for regular fixed bills(which wages go in to, and standing orders to my other savings / day to day account) and day to day spending, I also have savings accounts for things like medical bills(glasses and dentist mainly) and car maintenance.
Your IP has a duty of care to ensure that the IVA is supervised in accordance with its specific terms and conditions. If the IVA proposal states that it fails in the event that three payments are missed, there is little they can do about this apart from to understand your difficulties and see if a viable alternative proposal can be submitted.
