A -- Bmeans A and B are spouses.
A -- B |____|Means that they had some children.
A -- B |____||___| c1 c2 c3B has a child from a different marriage. c = child. The same statute: §852.01(1)(a)1 : it doesn't matter about c3. As long as both A's kids (c1 and c2) are also B's kids, B gets it all. "Issue" is defined in §851.13, and it does not include people without a parent-child relationship (i.e., blood children and adopted ones).
P |___| A -- BP is a parent of A. So, looking at UPC § 2-102(2), we decide that B gets $200K + 75% of what remains (75% of $400K = $300K) so $500K to B. And we might guess that the remaining $100K to parent. Note that in WI, B would get it all. But parents aren't mentioned in § 2-102(2)-- it does not give authority for giving to parents. §2-103(2) is where we get that authority: $100K to parent.
But wait! The family was domiciled in WI. This means that all property is presumed to be marital property. Ownership is not determined by title: in WI, a house might be marital property even though only one name is on the title. Also cars, etc. So under WI law, the property is presumed to be marital. ("Rebuttal by acquisition of title:" we could rebut the marital presumption by finding evidence that the property was acquired before 1986 or something).
But wait again! What does ND care about WI's ideas of ownership? ND law applies, but ND can look to other jurisdictions (this is a standard thing: both statutes and case law look to laws of other jurisdictions). So we look to the jurisdiction that has the strongest interests at stake. ND has the strongest in who commits waste on the land, or who develops it, etc. But not in who owns the property. This is why a WI spouse can't just empty a bank account, drive to a non-community-property state (IL) and open a bank account. There's an act (Uniform Disposition of Community Property at Death) that about 8 non-community-property states have passed which recognizes community property brought into the state.
ND isn't going to go looking for community property-- it requires a proactive claim. But if it's community property, there's not $600K in probate, only $300K. And so then we give $200K of that, plus 75% of the remaining $100K ($75K) to the spouse, and $25K goes to the parent. So the difference here is whether parent gets $25K or $100K (a difference of $75K). This is right on the cusp of whether it's worth fighting about-- getting experts to ND to testify about community property and how it should be recognized and stuff.
Ultimately, we don't know what will happen: much will depend on who cares. The surviving spouse and the surviving parent are the decisionmakers here: maybe they want to just let the spouse have it. Or not, but they might still be able to settle things without going to court. ND law applies, and ND should (but may not) recognize the community property. So we might end up with a few different results, and the first guess could be the ultimate outcome.
