It may be possible to end your IVA early if you wish to pay a lump sum. Please contact us first as we can arrange a variation meeting with your creditors to offer it and confirm any final settlement.
However, you will not be able to just cancel your IVA. An IVA is a legal process and both you and your creditors are bound by the terms. If you stop making the IVA payments then creditors will probably start bankruptcy proceedings against you.
