The matrimonial home
A confiscation order is an order to pay a sum of money and may be enforced against any property held by the defendant, even if some of that property was legally obtained. Accordingly, the matrimonial home may be seized and confiscated, if the defendant fails to pay. Subject to the operation of section 31 of the Family Law Act 1996, this may result in the eviction of other family members.
The effect of section 69(3)(a) POCA is to reverse the unreported case of Customs and Excise v A (July 22 2002, CA); a case in which it was held that a property adjustment order could be made in family proceedings notwithstanding the provisions of the Drug Trafficking Act 1994.
The court may not, however, order the realisation of any share in the matrimonial home owned by the spouse or partner, unless it can be shown that the share was a tainted gift (see R v Buckman [1997] 1 Cr.App.R.(S.) 325).
It sometimes occurs that the spouse of an offender petitions for divorce and seeks the transfer of the matrimonial home into his or her sole name in ancillary relief proceedings. Where this occurs, it may be necessary for the CPS to seek leave to intervene in the ancillary relief proceedings. The Proceeds of Crime Unit must be consulted whenever intervention is contemplated.
