My ex partner (we were never married but together for around 10 years) currently pays maintenence of £400 a month for our DS, almost 3 years old. He is quite a wealthy man - he owns farmland which he leases out, he gets around £40k a year for this. He has stocks and shares worth around 100k. Assets in total of about 2.5 million. Doesn't work, currently lives off his inheritance, or interest off his stocks and shares (not sure exactly, but I know he doesn't work).
He does also pay half of our sons nursery, his half comes to £264 (DS is in nursery part time). So in total, my ex pays £664 per month to me.
I'm struggling financially although I wouldn't like to admit that to my ex. He and his partner have bought their house outright, mainly off his money, so no mortgage while I'm still trying to save a deposit. I can only work part time at the moment.
WIBU to ask ex for a little more maintenence? If so, how much should he be paying? He pays the current figure as I calculated 12% (the amount I believe the CMS use) of his income (passive income, the land) and I came to a figure of £400 p/m.
He does also have a child with his current partner, who not long turned 1.
I don't want to seem grabby but I am working and desperately trying to save a house deposit to give my DS a permanent home (we currently live with my family), after he walked out on us when my little one was 3 months old. Impregnated new partner within around a year of our baby being born. Him, new partner and baby have a financially confortable life and here is me struggling away.
WIBU to ask him to increase his maintenance?
