I was wondering whether the average mustachian here has a will, and at what point (wealth, family, age, (or risky life style 
)) it would become useful. Seems in Zurich spouses and children are tax excempt, so no optimization necessary in that regard.
Additional, there are also forced heirship rules, but I am not to clear on thoseā¦
Iād be curious to hear what yāall have though about in this regard.
I have. 20% each for GF, 2 brothers and my parents.
I know that my parents have a legal minimum of 50%, but this will change in 6 months.
Yes I do. Used some online app to get a solid version before I handwrote it.
What do you mean with āit will changeā? The law?
Can you share which app? Thanks!
No I do not. But I want the 100% go to my wife. So this is the default one.
Same here. Donāt want to bother AND what I want is a default option. But I store some printouts with information about my brokerage accounts etc in a place where it would be logical to look for it.
probably going to marry his gf (or someone else 
)
The law will change. The 50% minimum for parents with unmarried people (like me) will drop to 0. So someone that isnāt married can decide on the whole 100%.
This would change the situation, but he then would still not be able to distribute his wealth evenly between these 5 persons, instead his wife would get min. 75% ā Fedlex
"Art. 471
Der Pflichtteil betrƤgt: (ā¦)
3. fĆ¼r den Ć¼berlebenden Ehegatten, die eingetragene Partnerin oder den eingetragenen Partner die HƤlfte."
Am I missing something?
Just used the first google hit
No you are right, I accidentally used the wrong article stating the default, not the necessary part.
Still the plan wouldnāt work to distribute it evenly between the 5 persons 
If it were that simple 
My oldest son will turn 18 soon. Heās disabled, and will not be allowed to take financial decisions himself (heād spend all to buy chocolate probably ā it could be worse evidently). I guess, but am far from an expert, all that he inherits would end up with the state.
Of course, the state supports him in may ways including financially, so it is not entirely unfair or undesirable. Regardless, if we could arrange things more efficiently, so that he can profit personally in a different manner (we own a holiday cottage in France he loves to visit, could it be maintained with his part while his bother has ownership etc.).
We were discussing this, and will get professional advice; however, it got me thinking about the issue and wondering what others here think about the issue.
With his salary and new hairline, he definitely wonāt run short of girls heads over heels to marry him.
As a relentless optimiser though, he would never risk falling short of the maximum AHV/AVS pension.
The law changes only in 2023. Until then, your will goes against the law and could therefore be challenged by anyone.
Oh well, so lets hope I donāt die in the next 1.5 years 
Any idea how this stuff works anyway? If you are a resident of country X but a citizen of country Y, which countryās rules decide? I didnāt bother with a will, frankly I donāt care what happens once Iām dead, I trust that whatever the rules are, they are somewhat fair.
Generally, country of residence. Though, sometimes the place where you wealth is located makes a difference too (US!).
You indeed are missing something:
As you might know, all the money made while being married counts as āgeimeinsame Errungenschaftā (shared accomplishment?), meaning it belongs to both of the married persons, regardless of who earned (or lost!) it. In the event of death, 50% of it immediately becomes the property of the surviving person. The other half becomes the estate, which will be distributed according to the will of the deceased person. It is mandatory that at least 50% of the estate goes to the husband or wife.
So, in the ideal case that all the net worth of a married couple consists of āgemeinsame Errungenschaftā (meaning both had zero net worth when getting married and no inheritances), indeed 75% (50% of the net worth + 50% of the estate) of all the money goes to the surviving partner.
