Hi nb and welcome to the forum
The advantages for you of an IVA over your current DMP are thatn your payments will cease in an IVA usually after five years, whereas in a DMP you will continue paying until the debts are repaid in full.
The Insolvency Practitioner's fees will be set by the creditors and will be deducted from the payments you make into the IVA.
If you enter into an IVA before your husband receives his back pay, then you can expect to pay over 50% to creditors on top of your ongoing contributions.
Only you can decided if it is sensible to try and IVA instead of the DMP. I can see definate advantages of the procedure for your husband, but you could be better off staying with the DMP - depending upon the allocation of your individual disposable incomes.
