This is a very good question.(posted 8017 days ago)Sending in an income and expenditure form makes it drag on regardless of your position because it encourages lenders to ask you for a certain amount per week or per month. That amount may well be, say, £5 for people in your position.
But... each year they will "review" it. Which means they ask you to fill in another income and expenditure form with a view to increasing it as soon as possible. I also know of some cases where lenders simply demanded more after a period of time regardless of whether the repossessee was earning more money or had acquired assets.
In terms of whether sending in an income and expenditure form makes any difference to whether you get sued or not... Regardless of what you tell them, they will have you watched carefully with a view to finding out what you earn, who you work for and what you own in order to decide whether or not it is worth trying to take you to court.
You - and possibly your relatives - can also expect funny phone calls from the "Inland Revenue" to find out your details in order to send you a "rebate".
In summary: the decision to stop hassling you is not dependent on whether you fill in an income and expenditure form or not. It is dependent on the costs versus the benefits of continuing to hassle you.
The decision to sue you is also not dependent on whether you fill in an income and expenditure form or not. It is dependent on the lender's independent assessment of the costs versus the benefits of suing you.
