Mo you must take cms.
He's older right? He may only be working at that level of income for five years.
So you need the high level now, if only to save lots of it.
The non married bit lessens the protection to the children in terms of assets. Divorcing is always about protecting the needs of the children. Well you're at great risk there because no claim on pension, no claim beyond 50% of house.
If he is an evil bastard then he'll simply retire! Mind you, I expect cms do take pension as his income but the percentage would greatly reduce.
Get as much money that is rightly due to the children for as long as you can.
Also in order to get your own mortgage you need proof of income of maintenance. I've just been through this.
Most the lenders scoff at any income from the Govnment. So no tax credits, no child benefit.
My tax credits pay my entire childcare bill so it's zero'd out. But the two go completely against each other.
Child care you say? Asks Mr Mortgage? Sorry. No. Your outgoings are too high.
Maintenance ? Yes. But only if court ordered or CMS. Two years proof of maintenance was required. I had to give two years of bank statements.
Jumped through bloody hoops. And they made me feel like shit..... We're not sure if the underwriters will be willing to lend to you..... Says snooty boots doing the application.
Please. It's not about trusting him. It's about proper documentation for future stuff and protecting the children.
