If there is a matrimonial settlement, which provides for a deferred interest in a property such as is evident in this case, this asset vests in the Trustee and will be realised when appropriate. The Trustee will secure his interest by obtaining a charge in accordance with Section 313 of the Insolvency Act 1986.
The 3 year rule to which you refer, only relates to a property which is the principle residence of the bankrupt - not a former spouse - and in any case only refer to the commencement of proceedings. A Trustee can obtain a suspended possession order or even a charge giving an infinite time period in which to realise his interest. So the provisions of the settlement are absolutely binding, and will be secured by the Trustee in the interests of creditors.
Legal ownership of the property may well be transferred to the party who is to remain resident in the property with the children, however this does not excuse the securing of a beneficial interest in the equity as set by the agreement.
If the transaction was deemed to be at undervalue, the 5 year provisions would apply - but no Trustee worth their onions would fail secure the position for the benefit of creditors.
