Before same-sex marriage became legal across the land, some states (MA, NH, DE specifically, I think, but I could be wrong) enacted legislation to protect unmarried same sex partners in this exact situation and it applies equally to unmarried hetero couples as well.However, children - particularly minor children - have some protection here as well and a court would not necessarily ignore them in favor of an unmarried partner, particularly if the house was the sole asset of the decedent.A married spouse usually receives all assets of the decedent and if the girlfriend can claim common law (or if it was already established prior to his death) through the state they were living in, she could receive it all.That said, I do not believe the mortgage company will permit a dead person to remain on a mortgage once probate is settled, so the house would have to move into a trust or to somebody else's name and the ex-wife would then be able to remove her name from it and move on.So yeah - I'm thinking out loud, but the above are all issues or question I would ask a SUPER COMPETENT attorney.

Today he would go to prison as a sex offender.

@JR T This article says, "Courts have long held that hiring on the basis of sex is permissible where sex is a bona fide occupational qualification in the context of serving privacy interests." 

It's discriminatory because you are biased to wanting a family and are discriminating against adults who are not a traditional family.The Fair Housing Act, which is the federal law governing housing discrimination, includes the following seven protected classes: race, color, religion, national origin, sex, disability, and familial status.I think you are technically right, that normally people get in trouble for discriminating against children than toward them, but better to set up your processes and posts so that you are blame free.

I'll come say hi while I'm staying in Mountain View later this week.A successful RE investor once told me "Sex and real estate, get a lot while you're young."

Her son was about to get out of prison and register as a sex offender.

Over the past few years my business (sex therapist) has really taken off.   

I can see some in here having a non-premarital sex clause.

Placing strangers together can have challenges even when people are the same age and sex, but mix up those variables and it can get ugly.I was at fair housing training and we were specifically told even advertising housing as "college housing" is discriminatory, because it implies families are not welcome.One other caveat, if YOU are owner occupying the property, you can legally discriminate against the other occupants.
