Lend only what you could afford to lose, decide gift vs loan explicitly, and if it's a loan, document it — that protects your child (clear expectations), you (a real claim), and their siblings (visible fairness). This guide helps you make the decision and shows what the paperwork looks like.
You can lend money to your adult child and keep the relationship intact if three things are true: you could afford to lose the money without hurting your own security, you've decided clearly whether it's a loan or a gift, and you're willing to put the terms in writing. Here's a calm way to think it through.
First, a gentle reality check on your own finances
The most important question isn't about your child — it's about you. Lend only what you could afford to lose without it affecting your own security, especially your retirement. It's easy to want to give a child everything, but a loan that quietly erodes your own stability helps no one in the long run. If the amount would stretch you, it's wiser and kinder to offer a smaller sum, or a different kind of support, than to put your own footing at risk.
Loan or gift? Decide on purpose
This is the fork in the road, and it deserves a conscious choice rather than a vague drift. A loan is money you expect back. A gift is money you don't. Both are perfectly valid — what causes pain is when you mean one and your child assumes the other.
Say it plainly: "This is a loan, and here's how I'd like it repaid," or "This is a gift, no repayment expected." Either way, write it down. If the money is helping with a home purchase, the distinction becomes financial as well as emotional — mortgage lenders and the CRA treat the two very differently, and you may need a signed gift letter or loan agreement. Our guide on family down payments: gift or loan explains exactly how that works.
If you decide to lend: do it properly
Choosing to lend doesn't have to feel cold or distrustful. The opposite, in fact — clear terms are what let everyone relax. Agree on:
- The amount and exactly what it's for.
- A repayment schedule you both find realistic.
- Interest, if any — many parents charge none, which is completely fine. If you do, keep it modest and within Canada's legal limits.
- Flexibility for life's surprises, agreed in advance.
Then write it into a short, plain-language agreement and both sign it. This protects your child as much as you: it removes any doubt about what was agreed, and it means you'll never have to send an awkward reminder text. The document remembers, so you don't have to. You can draft one in a few minutes and both sign from your phones.
Why writing it down protects the relationship
It may feel strange to formalise a loan to your own child. But consider the alternative: an unwritten loan relies entirely on two people's memories staying identical for years. They rarely do. One remembers a firm repayment date; the other remembers "whenever you can." That gap is where resentment grows. A signed agreement isn't a sign you distrust your child — it's the thing that keeps trust intact, because nobody has to wonder or re-litigate later.
Canadian courts have seen many family loans unravel precisely because nothing was written down — you can read about real cases where a family loan needed to be in writing. And if you're weighing whether a casual understanding is enough, here's whether a verbal loan agreement is legally binding in Canada.
If you decide not to lend
"No" is a complete and loving answer. You can decline the loan while still offering support — help thinking through a budget, a smaller one-time gift, or simply being honest that it's not something you can do right now. Protecting your own security, and not setting a precedent you can't sustain, is a perfectly good reason. A clear, kind no is far healthier than a reluctant yes that breeds quiet resentment on either side.
The bottom line
Should you lend money to your child? If you can comfortably afford it, you've decided clearly whether it's a loan or a gift, and you're willing to put the terms in writing — then lending can be a real and lasting help. If any of those aren't true, slow down. The decision that protects both your finances and your relationship is always the clear one, written down, made calmly.

Create my loan agreement →Common questions
Should I lend money to my adult child?
It can be a genuine help, but only lend what you can afford to lose without hardship, and be clear whether it's a loan or a gift. The healthiest family loans have agreed terms and are written down. If lending would jeopardise your own finances or retirement, it's usually wiser to offer a smaller amount or other support instead.
Should money to my child be a loan or a gift?
Decide deliberately and say it out loud. A loan is repaid; a gift is not. Whichever you choose, put it in writing — a signed loan agreement or a gift letter — because if it's ever disputed, what you intended at the time is what counts. This matters most if the money goes toward a home, because mortgage lenders and the CRA treat loans and gifts differently.
How do I lend money to my child without ruining the relationship?
Agree on the amount, repayment, and any interest before the money moves, and write it down so no one relies on memory. Keep the tone warm and treat it as a normal arrangement between adults. The written agreement is what lets you avoid awkward reminders later, which is usually what causes friction.
