If they are nothing to do with the IVA and the money is in their name then it is theirs to do with as they will as far as I am aware.

The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

As Kallis says -- as long as the inheritance is clearly in their names it cannot be drawn into the IVA. I would add the caveat that one "charity" firm do consider "household" income to be all fair game, so they might take a different view.
My opinions are merely that .. opinions based on experience. Always seek professional advice.

Hopefully the answers above give you some relief. Your childrens money is theirs and should not be taken into account with your savings or income. In fact your IP need mot even be informed of it in my opinion so long as it doesn't hit your bank account in anyway enroute to your childrens accounts

There is a solution for everyone .... Just need to stay positive !
Our children's affairs (who became adults during the IVA) were never questioned in any way during our IVA.
But we got the budgets for them all the way through.
IVA completed with StepChange.
