When a debt is secured - it is attached to a particular assets - eg a property, so that if the property is sold, the secured debt will be paid from the proceeds. Usually, secured creditors will only lend a certain percentage of the value of the asset - to give them a little leeway in respect of fluctuating values, but occasionally they may find that they are in a shortfall postion - for instance if the asset devalues or the borrower fails to honour their payments. In which case they are allowed to treat the shortfall as an unsecured creditor.
Revaluing security can be done at any time by a lender, if they feel that there may be some risk to their security. For instance when property values drop. This means that they allocate more of their claim to the unsecured element, and less against the value of the asset.
Don't think I've explained that very well - but the priniciple is that it is down to the secured lender to decide on the value of their security - which can be revalued at any time during the course of an IVA.
