Lending money to family feels like the right thing to do, and often it is. But without structure, that loan becomes something else: resentment at holiday gatherings, whispered accusations of favoritism, or a lawsuit after someone dies. Families who avoid this treat internal lending like what it actually is, a real loan with real paperwork.
Why handshake deals go wrong
The pattern repeats with depressing regularity. A parent lends a child money to start a business. No paperwork, no interest rate, just a verbal agreement and a check. Years later, one sibling is furious that another received what looks like a gift disguised as a loan. The borrower insists they meant to pay it back. Nobody remembers the exact terms.
There’s also a tax problem hiding inside the family drama. When someone lends money at below-market rates or charges no interest, the IRS can treat the difference as a gift. For small amounts that might not matter. For larger loans, it can eat into lifetime gift tax exemptions and trigger reporting requirements nobody planned for.
The fix is a formal promissory note specifying the amount, the repayment schedule, and an interest rate at or above the IRS Applicable Federal Rate for the loan’s term (short-term covers up to three years, mid-term three to nine years, long-term anything beyond that). Those rates change monthly and currently sit well below what a commercial lender would charge on comparable terms, so the borrower still gets a better deal than the bank while the lender avoids gift tax exposure.
Build an approval process that removes the emotional pressure
When a family member asks for money, the person being asked usually feels put on the spot and says yes before thinking it through. Families that handle this well take the decision out of any one person’s hands. Smaller amounts might only need a simple agreement between two parties, but once a request crosses a meaningful threshold, commonly cited around $50,000, the decision shifts to an independent reviewer such as a CFO or trusted advisor, or requires sign-off from multiple senior family members.
This isn’t bureaucracy for its own sake. When a request has to go through a process instead of a single relative, nobody feels personally rejected if the answer is no. Policies that define what the money can be used for, a first mortgage, education, an approved business venture, also keep the family bank from turning into an open-ended source of lifestyle spending.
Decide the default rules before anyone needs them
Every family loan program needs a written default policy before the first loan goes out. A common approach ties an unpaid balance to the borrower’s future share of the estate, which protects the family’s overall wealth while keeping accountability real. Some families allow restructured terms for a first default; others are strict from day one. The specific policy matters less than having one, applying it consistently, and documenting every payment so a dispute years later, during a divorce or an estate settlement, doesn’t come down to memory.
Take the collections role off a family member’s plate
Even with a signed note, someone still has to track payments and flag the ones that are late, and that job usually falls to a relative who ends up feeling like the villain while the borrower feels like a failure. This is why families increasingly hand the administrative side to a third party that tracks principal, calculates interest, and sends reminders from an institution rather than from a parent or sibling (firms such as Digital Ascension Group specialize in this kind of administration for family lending programs). The lending decisions stay with the family. The collections dynamic goes somewhere else.
Make it a system, not a one-off favor
Families who do this well eventually write a charter that defines the purpose of the family bank, who approves what, at what thresholds, and what happens on default. That documentation creates shared expectations: everyone knows the rules before they need money, and everyone knows they’ll be treated the same way. Most conflicts that break families apart by the third generation trace back to perceived unfairness around money. A documented family bank with consistent third-party administration heads off most of that before it starts.
You don’t need a nine-figure fortune to put this in place. A clear promissory note, an interest rate at or above the AFR, a defined approval process, and someone tracking the balances gets you most of the way there. The goal was never to prevent the loan. It’s to make the loan work for everyone involved, so the money stays in service of the relationship instead of competing with it.
