So a bit of a back story, my ex husband and I separated in September, from then until January he payed me no child maintenance for our 4 year old son. Due to this I was forced to go to the CMS to get maintenance. Whilst we were together he was earning over 100K per year, then when I went to the CMS, all of a sudden he has had a 50K pay cut. Therefore he is paying me less than £200 per month. Now he has just applied for a variation on his payments to take into account for the car that I use. This is a marital asset and will need to be resolved during the divorce. The car is registered in his name and he pays for the finance. I pay for the insurance, tax, mot maintenance etc. Question is, is he now going to get way with paying me even less?
