Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
What income do you each have?
Will that continue when she moves out- will she still work in/for the company?
You should write back to the solicitor pointing out that the car is a family asset and essential for your work.
Confirm that you will of course meet the monthly payments and that as soon as the overall settlement is agreed and you are able to do so you will settle the debt.
Tell them that is this is not acceptable and your wife goes ahead with her plan then you will have no income form which to make the payments she has requested - and of course it will seriously impact her financial claims upon you.
If the divorce petition has been issued you could add that your other option is to make an urgent financial applictaion for an order prohibiting the sale of the car which owuld increase the overall costs - and that if you have to do that you will ask the court to consider making a costs order against them.
I hope that this is of assistance - please ask if you need further details
How long have you lived together and what employment skills does she have?
The length of your relationship and the fact that she has been out of independent employment for a few years means that interim spouse maintenance is a certainty - with a year being a likely minimum - and no it will not be deductible at the end.
£600 a month whilst matters are being resolved is reasonable
