hi bunblebee,
sorry you are in this situation.
unfortunately, if you start a 'normal' application for ancillary relief (financial support) through the Court at the same time as issuing divorce proceedings, it is not going to happen overnight. What usually happens is once you issue proceedings, you will get a Court date for a First Directions Appointment. This is usually around 12 weeks after you have made the application and between the time of issue and the appointment, both you and your ex will have to complete and file (send to Court and other party) financial statements (Form E) setting out all your financial information, ie assets, income, outgoings, pension etc. (Usually filed/served 35 days prior to hearing) Once exchanged you will have the opportunity of going through each others Form E and preparing a Questionnaire (based on info in form) and request for further information. This is usually filed 14 days prior to the hearing but does not need to be replied to before it. At the hearing the District Judge (DJ) will consider the Form E's, questionnaires etc and make an order with regards to the answering of the questions and request for documents. The matter will then usually be listed for a further hearing, a Financial Dispute Resolution Hearing (FDR), usually around 3 months later, depending on the court listing/waiting times. Both parties will be encouraged to negotiate in order to try to reach an agreement without the Court having to make an Order. At the FDR (in not previously settled) the DJ will give an indication as to what he/she would order if they were hearing the matter as a final hearing. Again, you would be encouraged to reach an agreement but failing that, the matter will be listed for a final hearing which potentially could be up to 12 months from when you first issued your application.
Clearly, given the timescales, that really doesn't help you now. (I've simply spelt this out for you so you understand what the 'normal' proceedure is, not to scare you)
In your circumstance, clearly you cannot wait this long if your ex is refusing to pay you money now.
you therefore will need your solicitor to issue (at the same time as your divorce petition) an application for Maintenance Pending Suit. This is a much shorter process and usually only used when in circumstances such as you describe. You would get a hearing much quicker and at the hearing the DJ would normally take a 'broad brush' approach and order that your ex pay you a set sum in the interim to cover your immediate needs. You therefore need to have a figure available to cover all necessities, ie mortgage, council tax, utilities, food, household etc. Your ex would be encouraged to recommence paying your money immediately (before even the matter went to Court if he had a solicitor) as quite often the Court take a very dimm view on men who basically turn off the tap in the way he is threatening. I'm pretty sure if you instructed a solicitor immediately and he/she wrote to him threatening an application for MPS hopefully he would use his common sense and begin paying the money to you to avoid court proceedings. If it was necessary for you to make such an application, it is probable that your ex would be ordered to pay your costs.
If you haven't already made an appointment with a solicitor you should do so immediately and from what you've said, you should be eligible for public funding (legal aid) so try to find one with a public funding franchise if you can.
Of course you will be very worried about this but please try not to worry and phone a solicitor straight away, rather than wait until next week. Hopefully a letter to him threatening all sorts of nasty applications will give him the kick up the arse he clearly needs.
I won't bore you with the CSA route, it will take too long (for you to apply and get money as opposed to me explaining it) You need financial support NOW, not in 6 months.
Also, if he is still indicating he won't pay, contact your bank, try to get an overdraft and keep your mortgage company informed of the situation. Also, find out what benefits you are eligible for. Good luck x
