Can I exit my IVA before 5 years?

There are three ways exit an IVA:

Pay the IVA it off early in full settlement either by sale or re mortgage of a property or via a windfall or third party funds.
Make a acceptable offer to the creditors that is verified at a further creditors meeting.
Cancel the IVA by declaring yourself bankrupt due to being unable to pay any further payments.

Your Insolvency Practitioner will be able to advise you on your options and implications of exiting your IVA early.
