Thanks for your patience.
In order to obtain an order for sale of the property you have to use the Part 8 procedure. Essentially you are starting a fresh claim in order to force the sale.
The form to be used is the Part 8 Claim Form which you can download from the HM Courts and Tribunal/Ministry of Justice website. A copy of the charging order must be filed with the claim form.
In addition you must submit a statement with the claim form and must:
(1) identify the charging order and the property sought to be sold;
(2) state the amount in respect of which the charge was imposed and the amount due at the date of issue of the claim;
(3) verify, so far as known, the debtor's title to the property charged;
(4) state, so far as the claimant is able to identify –
(a) the names and addresses of any other creditors who have a prior charge or other security over the property; and
(b) the amount owed to each such creditor; and
(5) give an estimate of the price which would be obtained on sale of the property.
(6) if the claim relates to land, give details of every person who to the best of the claimant's knowledge is in possession of the property; and
(7) if the claim relates to residential property –
(a) state whether –
(i) a land charge of Class F; or
(ii) a notice under section 31(10) of the Family Law Act 1996, or under any provision of an Act which preceded that section,
has been registered; and
(b) if so, state –
(i) on whose behalf the land charge or notice has been registered; and
(ii) that the claimant will serve notice of the claim on that person.
The claimant must take all reasonable steps to obtain the information required by paragraph 4.3(4) before issuing the claim..."
You will see from the list that a substantial amount of information has to be submitted to the court before an order will be made.
You will need valuations and information about other charges, debts and interest which are likely to take precedence e.g. first mortgage, tax, secured loans, beneficial interests.
Once the claim form, charging order and all the evidence required above is submitted a hearing will be arranged for the court to make a determination. A sample order for sale can be found here ORDER
If she files for IVA or bankruptcy the order that debts are paid are usually as mentioned above e.g. mortgage, tax, secured loans and then judgment debts. Sadly your judgment is not classed as a priority debt but your interest is secured by the charging order - so at the end of the day something will be paid sooner or later.
The sale procedure, as you will have gathered is not straightforward especially if contested. You do not need a solicitor but it would be advisable to instruct one to help with the procedure - legal costs will be deducted from the sale.
Hope this helps. Happy to discuss further.
