I've been dating a man who's a Mexican immigrant. We want to get married but he wants me to sign a prenup. He has condos and restaurants and I have nothing right now. Some of his properties and resturants aren't even on his legal name. So I thought it was weird him ask me that. He has an attorney that is writing up a prenup "supposeably" I'm just more confused. I'm just saying a hard time understanding, is that even possible? Could he ask me to sign a prenup while being illegal?
The legality of a prenuptial agreement is completely independent of immigration status.
The converse of this proposition is not true. If you get married and have a strict prenuptial agreement the likelihood that immigration officials will treat the marriage as a sham marriage which does not qualify to allow him to receive a spousal visa for immigration purposes is great. While a prenuptial agreement isn't an absolute bar to having a marriage considered to be valid for immigration purposes, the more strict it is, the more likely it is that immigration officials will not recognize the marriage as valid.
Some of his properties and resturants aren't even on his legal name.
It is hard to know what you mean by this statement. It is common place for people to own companies that own properties and restaurants. It is not common for those properties and restaurants to be owned in the name of another individual who is not clearly held out to the public to be a trustee or fiduciary of some type, although it is probably not illegal for someone to hold property or restaurants in the name of an undisclosed nominee owner for any purpose other than liquor licensing.
So I thought it was weird him ask me that. He has an attorney that is writing up a prenup "supposeably" I'm just more confused.
If this leaves you feeling weird and confused, you may be thinking of the relationship in a different way than he is thinking of the relationship. He may be seeing you as a temporary stepping stone to citizenship who is not unpleasant, while you may be seeing this as a permanent relationship and life long commitment.
At a minimum, you should absolutely consult your own lawyer before signing anything, and he should offer to provide you funds to do that. If he doesn't, just say no.
