Hi Jenny and welcome to the forum
You are able to have an IVA if you have lived in the UK for the majority of the last six months, or have retained a permanent address within the UK, however I note that you only have two debts and, if so, an IVA will probably not be a viable option.
Do you have any other debts? If not, then I suggest you contact the banks and explain your circumstances. They may agree to take reduced monthly payments from you to avoid the need for a debt management plan, where you will pay for the services of a specialist company (unecessary in my opinion if you only have two debts). If this does not appeal to you, and you have no material assets, then you might wish to consider bankruptcy proceedings in the UK - again only possible if you have lived in the UK for the majority of the last six months.
French bankrupty law is somewhat more restrictive than English law, and involves a heavier involvement of the Court in managing the procedure.
