Hi --- As the Halifax had already agreed to a DMP arrangement that you were adhering to, they would get little or no co-operation or success on application to a judge for a charge order to be placed against your property......even though any creditor can apply for a CO they have to show that all reasonable steps have been taken in sticking to pre-existing agreed plans.
They may even be contravening the agreed banking codes of practice, perhaps a complaint to the FOS may help should this turn into a sinister effort to apply for a CO to be placed. Or it could simply be a perfectly innocent way of passing the troublesome debt onto their smaller debt collectors and get it out of their own system......possibly policy of their's. ?

To add ....a charging order cannot force the sale of your house without a long winded complicated process, but it can guarantee that the creditor is paid out of the eventual sale proceeds when the house is sold voluntarily by you, the Solicitor then becomes duty bound to re-pay the charging order in the same way as a secured loan against your property.
