A will names who inherits. It rarely says how to find anything.

A will answers one question well: who should receive what. It is the instrument for deciding that the house goes to one child and the savings are split between two. What it was never designed to be is a map. It says who inherits the accounts; it does not say which bank they are at, that the pension from a long-ago employer still exists, or how anyone is meant to reach the crypto.

The two jobs get confused because they feel like one. People assume that once the will is written, the family is covered. In practice the family can know exactly who inherits and still spend months just working out what there is to inherit.

The starting problem is that most people have neither part in place. Trust & Will's 2026 report found that 56% of Americans have no estate plan at all, and that the share with a will had slipped to 26%. Even among the minority who have done the paperwork, the document almost always stops at who-gets-what and never becomes a finding aid.

As Kiplinger's estate-planning coverage stresses, a full plan is also about the living: incapacity, health decisions, powers of attorney, beneficiary designations, and keeping all of it current. The through-line is that a plan is something you maintain, not a file you sign once and forget — and maintenance is exactly what a static will does not force.

A will is a public-facing legal document that may be read by a court and, eventually, by strangers. That is a good reason not to write passwords, account numbers or the location of a safe into it. So the very details a family most needs in the first week are the ones that correctly do not belong in the will at all.

That leaves a hole. The will handles ownership; nothing handles access. The account references, the logins, the note that the insurer is not the obvious one, the fact that there is a locker at all — these have to live somewhere else, kept current, reachable by the right person at the right time, and never exposed before then.

You do not rewrite your will to fix this; you add the layer it was never meant to hold. Keep an inventory of accounts and where they are. Attach the practical notes only you know. Decide who should be able to see what, and when — and keep the sensitive parts encrypted until that moment. Done well, it sits alongside the will and answers the question the will cannot: not who inherits, but how they will ever find it.
