Even if your spouse works and is able to work and isn’t on disability if your income larger than his, if he fights for alimony or for lump sum settlement, he could win, sometimes if you have investments (which you sayd you don’t) and they get half of that you might not pay alimony. Of course not everyone asks for alimony but if they do, they might get it.

But overall any time you marry someone who makes significantly less than you or worse don’t work at all, you risk to be on a hook for spousal support.

I know many people, both men and women, who ended up paying alimony for 5 years, 8 years, 10 years and in some cases of spouse being disabled (they could become disabled later in a marriage) you’ll pay until SS age. Any time they can show that everything purchased or leased is by you, it makes you look like a sole provider. Courts believe “disadvantaged” spouse deserve same life style they had during marriage until they can stand on their own two feet (if they ever could)

I am not trying to scare you but getting married isn’t about how wonderful was the wedding or how much fun was honeymoon. You need to know everything there is to know about the person including their health condition and most certainly finances and earning potential, and their expectations of marriage. Are they expecting you to support them, buy stuff for them and are you ok with it? You need to know this stuff before you enter legal agreement of marriage and if you discover more stuff during marriage you have rights to re-evaluate and protect yourself
