There is a ledger in your family, and no one has ever seen it. It lives in your son's memory of the year you covered his rent, and in your daughter's memory of the year you didn't. It records who got the car, who got the semester abroad, who got the money for the down payment that everyone quietly understood would never come back. You keep a copy too, though you would deny it if asked. And on the day you die, every page of that ledger lands on your executor's desk with one impossible question stapled to the front: was it a loan, or was it a gift?

The loan that three honest people remember three ways

Picture it. Your younger son hit a rough patch a few years back, the kind where the car dies the same month the job does. You wrote the check at the kitchen table. “Pay me back when you can.” He meant to. You meant it. Then a year passed, then three, and bringing it up started to feel like putting a price tag on love, so you stopped. Your older daughter never borrowed a dollar from you. She noticed the check. She noticed the silence after it, too.

None of these people is lying about what happened. They are just remembering it from inside their own lives. In a well-known 1979 study, psychologists Michael Ross and Fiore Sicoly asked married couples to estimate what share of household work each of them did. Add the two estimates together and they routinely exceeded one hundred percent. The mechanism is called egocentric bias in availability: your own contributions are simply easier to recall than anyone else's, so you weigh them more heavily, without any intent to deceive.

Apply that to a family loan. The borrower remembers the hardship and the words “don't worry about it.” The sibling remembers the amount. The parent remembers the relief of being able to help. Three ledgers, three balances, and no document to reconcile them.

Family therapists have a name for the invisible accounting underneath this. Ivan Boszormenyi-Nagy, the founder of contextual family therapy, described a “ledger” of fairness that every family keeps across generations: a running, mostly unspoken sense of who has given, who has received, and who is owed. Money is only one entry. When the ledger goes unbalanced for long enough, it tends to get settled in other currencies. Distance. Sarcasm at Thanksgiving. A sibling who stops calling.

What the law assumes when you say nothing

Here is the part most parents never learn. The law has a default answer to “loan or gift,” and it is probably not the answer you would have chosen.

For centuries, common law presumed the opposite of what you might expect. A substantial lifetime gift to a child was treated as an “advancement,” an early draw against their eventual inheritance, to be subtracted from their share when the parent died without a will. Modern law in much of the United States has flipped that presumption. Under the Uniform Probate Code, which many states follow, a lifetime gift counts against an heir's share only if the parent declared that intent in a contemporaneous writing, or the heir acknowledged it in writing. If you have a will, the will governs, and a will that says nothing about the loan treats it as if it never happened.

So the quiet default usually runs like this: the forgotten loan is forgiven, the gift is extra, and the daughter who never borrowed receives exactly the same share as the son who did. Whether that is fair depends entirely on what you meant. The law cannot read what you meant. It can only read what you wrote.

If you did document the loan, a different machine starts turning. An outstanding promissory note is an asset of your estate, like a bank account or a car. Your executor has a fiduciary duty to collect it, or at minimum to offset the unpaid balance against the borrower's inheritance. If your executor is the daughter who never borrowed, she is now legally obligated to pursue her brother for the money. If your executor is the borrowing son, he is obligated to pursue himself, in front of his sister. Old and undocumented loans may be unenforceable altogether once the statute of limitations has run, which means the decision you avoided gets made by a calendar.

The tax code has opinions too. Loans between family members that charge less than the IRS's published applicable federal rate can be treated as carrying imputed interest, and a “loan” that nobody ever expected to be repaid is, in the government's eyes, a gift, which may require a gift tax return if it exceeds the annual exclusion. None of this is catastrophic. All of it is easier to handle while you are alive than for your executor to reconstruct from a canceled check.

Why “I'll sort it out in the will” is not sorting it out

Many parents, sensing the problem, plan to handle it in the will. Forgive the loan there. Or quietly leave the borrower a bit less. Both are legally valid. Both tend to backfire, for a reason that has nothing to do with law.

In 1963, the psychologist J. Stacy Adams proposed what became equity theory: people judge fairness not by what they receive in absolute terms, but by the ratio of their inputs to their outcomes, compared against a relevant other. The sibling who never borrowed does not actually resent the bailout. Most people are glad their brother got through a hard year. What they resent is the bailout becoming invisible in the final accounting, as if it never counted. Fairness is a comparison, and a comparison needs information to run on.

A will that forgives a loan without ever having mentioned it reveals the debt at the worst possible moment: in a legal document, to people who are grieving, with the one person who could explain it gone. A will that silently reduces one child's share reads as punishment, because no one is there to say it was arithmetic. Grief plus ambiguity is the exact recipe for a will contest, and most contests are about process, not money.

There are really only three honest paths for any family loan, and each one works if you state it plainly:

  • Forgive it and call it a gift, with no effect on anyone's inheritance.
  • Forgive it but treat it as an advancement, so the borrower's share is reduced by what they already received.
  • Keep it as a loan, documented, to be collected or offset by the estate.

The choice is yours. The silence is what does the damage.

Your next moves

  • Write the ledger down today. On a single page, list every loan you have made to a family member: who, when, how much, and what was said at the time. Your own handwriting is enough to start. Then, next to each one, write which of the three paths you choose.
  • Paper any loan that is still open. A one-page promissory note signed by both of you, with a stated interest rate at or above the current applicable federal rate, a repayment schedule, and one sentence describing what happens to the balance at your death. Templates are widely available; the point is the signatures and the sentence.
  • Add a “loans and gifts” paragraph to your estate documents. Ask your attorney to include it in the will or trust, or put it in a signed letter of instruction kept with your documents: “I lent my son a sum in 2021. I forgive it at my death and do not count it against his share.” Or the reverse. Dated, signed, unambiguous.
  • Tell both children the same rule in the same week. Not necessarily the dollar figures, but the principle: “Money I lent is forgiven and doesn't change anyone's share,” or “Money I lent will be counted.” Hearing it from you, while you are alive, is the only version that doesn't feel like a verdict.
  • Decide before the next check, not after. The next time an adult child asks for help, say out loud whether it is a loan or a gift before the money moves, and write a line about it that day. A decision made at the kitchen table is worth more than any clause drafted in a lawyer's office years later.

The part your executor will thank you for

Most of what Heirloom does is unglamorous: it gives your family one place to find what you own, what you owe, and what you decided. Family loans belong on that map alongside the bank accounts and the deed to the house, with the decision attached to each one so your executor inherits an answer instead of a question. If you want a quiet way to keep that ledger current while you are still around to explain it, you can start at heirloom.lumenlabs.works. But the page you write tonight, in your own hand, is the one that matters most.
