Hi ralston and welcome to the forum
That will depend upon the circumstances of your separation, and the nature of any consent order you entered into regarding the transfer of your interest in the property to her.
If this was effected at a time when you had no debts, then there is nothing to worry about. If, however, you were insolvent at the time you entered into this transaction, your IP will need to consider the implications of this - as such transactions could be overturned under alternative bankruptcy proceedings - thus restoring your interest and making it available for your creditors. These actions are fairly uncommon, and rarely pursued by bankruptcy Trustees, but nevertheless you should take specific legal advice if you are worried.
Your pensions are safe within an IVA, but creditors often ask you to suspend payments for the duration.
