We really need Jenna1978 (one of AB's solicitors) or Barmaid (a barrister) here but, to the best of my knowledge (and using a 'common sense approach' to the law) there is no way that you get a charge placed on someone's property without either their consent or a court order.
Further, a charging order from a court is only available as a method of enforcement AFTER the property owner has defaulted on a previous court order for repayment of a debt.
