I’m in the process of writing my will, but I’m unsure about how I should split my estate among my children. Should it be divided equally? Or should I give more to one of my children, who needs it more?

It’s hard enough avoiding thinking about our own mortality, but then we also have to contemplate the ructions that could erupt after we depart the mortal coil. Is that fair? Probably not. But at least you can attempt to be fair in how you dole out your mortal leftovers. 

The good news is that philosophers have spent centuries coming up with ways to carve up a bundle of stuff – whether that’s a pie, a national budget or a deceased estate – and distribute it fairly. The bad news is they haven’t settled on just one right way to do it. Still, if you care about fairness, then there are a few approaches you can take. 

The simplest is to just split things perfectly evenly. Say you have $100,000 left in the bank; you have four children: you divide it four ways, so they get $25,000 each. Simple. That’s called “strict egalitarianism,” which says that stuff should be distributed so that everyone ends up with exactly the same amount. 

But my youngest child has had a string of bad luck that has left them struggling to get by. Meanwhile, the three older ones are cruising. Does that mean I should leave more to the needy one and less to the others?

And therein lies a problem with strict egalitarianism: we don’t all start off in the same position. So sharing stuff around equally might just exacerbate existing inequalities. Like, it would be weird to cut a pie four ways and give an equal slice to each diner if three of them were stuffed full and one was starving to death.  

That’s why the “welfare approach” urges us to think carefully about how each individual is going right now, and make sure that we distribute our stuff so that it generates the maximum overall welfare for everyone. So, if three of your children are doing well – i.e. their welfare is currently high – and one is lagging behind, then it would be fair to give the one who’s struggling a bigger slice of the pie.  

That doesn’t necessarily mean they should get all the pie. Things like money and pleasure often have diminishing returns. So giving everything you have to the struggling child might not elevate their welfare much more than just giving them half. And it might turn out that giving a small amount to the three children who are better off will still make a significant difference to their welfare. So get your calculator out, start plugging in welfare values, and run the numbers to see who gets what. 

Look, I hear you, but my older kids say that my youngest is an idiot, and keeps making terrible decisions, like investing all their money in crypto. Would it be unfair to the others if I just propped them up?

Speaking of divvying up pies, this brings us to the idea of “dessert”. Fairness is not just about making sure that everyone ends up on even footing. It can also mean rewarding those who work hard and act responsibly, and not coddling those who are lazy and irresponsible. If you keep feeding that hungry person pie, then they might not bother making themselves dinner and rely on your charity to keep them fed. 

So, the dessert-based approach says you should think about how much of your fortune each of your children deserves. You might look at how hard they work, or how much they contribute to looking after their families, or how much time and energy they have spent caring for you. 

Well, if that’s the case, then none of them deserve it, because they all forgot to call me on my last birthday. That said, I do like the idea of making sure my inheritance goes where it can do the most good. I’m just not convinced that it can do so in the pockets of my ungrateful children.

Then perhaps you need to broaden your horizons beyond your family. Even a small donation to the right charity can transform lives, producing far better outcomes in terms of welfare than giving it you children, especially if they are already living comfortably. 

In fact, it’s well known that inheritances are a major contributor to perpetuating intergenerational inequality. Rich people give their stuff to rich kids, who can use that to generate even more riches throughout their lifetime. I mean, have you seen the property market these days? It’s almost impossible to get in without an inheritance propping you up. So what do poorer people do?  

That’s why economists say one of the best ways to flatten the wealth in a society is to tax inheritances, especially big ones. Although that policy is strangely unpopular with many voters, especially those who own multiple properties. Go figure. 

So, if you decide to break the cycle and do the most good with your inheritance, there are plenty of charities that will more than happily distribute it to those with the greatest need. Just don’t expect your kids to be thrilled with your decision.
