If you think an IVA is not suitable for you, there are other alternatives:
A Debt Management Plan is an informal arrangement between you and your creditors. Unlike an IVA it is not legally binding, which means that it is much more flexible than an IVA.
With a Debt Management Plan you will be able to negotiate affordable monthly repayments, and your creditors will hopefully to agree freeze interest and charges.
Bankruptcy is the most serious debt solution, and should only be considered when all other options have been exhausted. Only take professional advice from a Licensed Insolvency Practitioner.
Bankruptcy means that you will lose your home, whereas with an IVA you will be able to keep your home, although you may have to release some of the equity.
