Planning divorce not yet married

[Loomy]

Thinking about getting married but want to cover all eventualities and see who is in the better/worse position and if it puts either of us in a difficult position.

My situation: renting in nice semi council house, couldn’t afford to buy on my own except possibly 2 up 2 down in worse area. Working just above minimum wage. No pension. Adult DC at uni and teen DC with SEN. Will inherit poss 150-200k in next few years.
His situation: Earns just under 3x more than me. Has good pension. No DC. Could easily buy a house on his own albeit with a long mortgage. No inheritance. Significant car payments which he wants to keep I.e continue to buy expensive cars on the never never.

YABU don’t do it
YANBU go for it.

I think he's more likely to benefit than you from marriage so I'd be cautious.

Why are you getting married? Doesn't sound like you're that young, you already have older kids so why get married at all? Especially if you're not sure.
Just live with or be together apart.

Do you need to get married? If you’re thinking about divorce already I’d say don’t bother in light of your inheritance.

In purely pragmatic terms, if you’d want to protect any future inheritance for your children, then either reconsider marrying, or at the very least, get some good financial advice before you do.
