Simon -- What date does it give for the case.?..... It sounds like they have only applied for an AEO and the case has yet to be heard pending a successful court ruling in which MH hope an order would be made.
The paperwork you have been sent should have a defence form N9B to fill in if you dispute you owe this money, if not get one at your local court, fill it in and the particulars form enclosing copies of letters you are using in your defence, it is preferable to attend the hearing also in order you can let them know that MH have provided no proof whatsoever that your partner owes this money, that they have totally failed to comply with your reasonable request so far to produce any evidence......this will get the case thrown out, === Don't forget to ask the court for your costs incurred i.e. time off work and travel costs.
Note -- If you do not defend then a "judgement by default" will be issued against your partner, failing any defence or representation being made by your partner.
..........................
If you want to defend against the claim you should:
Return the 'Defence Form' N9B to the issuing court
Answer all the points raised ('allegations') in the particulars of claim
Make sure the court receives the form within 14 days (allowing at least two days for posting)
.............................
If your defence is complicated and you need more time to respond, you can fill in the 'Acknowledgment of Service Form' N9.
If you file an acknowledgment of service within 14 days, this will allow you an extra 14 days to complete the defence form.
If an order has already been made then an application for it to be "set aside" can be made, let us know. !
