A grandmother in Colorado left her ski house to her four children. She wrote rules to keep it in the family. The children are in their 70s now. Only one of them uses the place regularly. That sibling's kids and grandkids grew up there. Many of the other cousins have rarely visited. Some will likely want to sell once it passes to them.
Christina Wing tells that story in the Weekend Review. She's on the faculty at Harvard Business School and advises family businesses. She calls the pattern the ‘cousin problem.’ Parents leave an asset to their kids and trust them to share it. Siblings have spent a lifetime arguing and making up, so they've built some trust. Their children are a different group. Once the grandkids own it together, the teamwork often breaks down. Wing writes that just one American in four feels very or extremely close to a cousin. Families are smaller now, and cousins tend to live far apart.
The branch-line math
Here's the math that matters. Say a founder splits a business evenly among four kids. One of those kids has a single child. Another has four. The single grandchild could end up with a 25% stake. The four cousins in the big branch could get 6.25% apiece. Wing calls it the ‘branch-line problem.’ It made sense to the founder. It can feel unfair a generation later. Her opening example is the family that controls Brown-Forman (BF.B). George Garvin Brown started the company in 1870. Today more than 100 living descendants and spouses control it, and many are cousins. The Journal reported in August that the stock had lost more than half its value over five years. That slide fed a family split, public fights over where the company is headed and a debate over a $15 billion takeover offer. BF.B is held at weight in one book; nothing added.
Wing's three fixes are simple to say and hard to do. First, set aside some ‘sweat equity’ for the heir who does the work. A founder with three kids might leave each 25% and hand the last 25% to a trustee to divide later by who helps run things. Second, build the bond before the asset moves. A Saudi family business she works with has 144 cousins who will share it one day. From age 15, they learn the family history and get training in personal finance. A Brazilian family with 40 fourth-generation cousins pays for a group trip every two years. Third, expect the cousins' lives to differ. One might grow a share into billions. Another might struggle to pay a child's college bill.
The same Review section ran reader mail on a harder split, estrangement. One reader noticed how many parents in the comments bragged about cutting an estranged child out of the will. That reader answered with the math nobody likes. Monthly care bills in the five figures can eat a small estate, and then Medicaid steps in. Another reader's rule was short. “Don't weaponize money or inheritance but don't give unconditionally either.”
Our read
This is an Estate story. Equal isn't the same as fair. A will that splits things evenly among your children can hand your grandchildren a lopsided deal and a room full of near-strangers. Wing's line is the one to keep. “If you want heirs to act like a group someday, help them become one.” That's a planning principle, not advice for any one family.
Here's the check for this week. Pull out your own will or trust and count the branches. If a cabin or a business goes to your children equally, sketch it one generation on. Write down each grandchild's share and who pays the property tax and repairs today. Then put the rules for selling on paper, and name the person who breaks a tie. And check how a long stay in care would be paid for, since those bills can empty an estate before anyone inherits. If the sketch looks lopsided, bring it to your next plan review while the person who wrote the will can still change it. You check the roof before the storm, not after the first leak.
