IF DH2B was family (but he's not) I'd strongly advise him to have home in both names. I've been married 33 years, don't fear DH turning away, but have always insisted cars and homes be also in my name. If DH2B will be helping with downpayment, mortgage or anything, it is his right. But as we know, we are not related. No one knows the future, I never thought MS.
