Sign a promissory note online so a good loan stays a good relationship.
Lending money to a friend or family member is an act of trust. Writing it down isn't a sign you distrust them — it's how you make sure nobody's memory has to be the referee a year from now. Dated, tamper-evident, and defensible.
"We'll just remember the terms" is how it goes wrong.
Your brother needs help with a deposit. A friend's car died and payday is two weeks out. You want to help — and you do. But six months later, the details get fuzzy. Was it $2,000 or $2,500? Was there interest? Was it due in the spring or by the end of the year? Neither of you is lying; you just remember it differently. And now a loan that was supposed to help is quietly straining the relationship.
A promissory note fixes this before it starts. It's a short document that states the amount, the repayment date, and any terms — signed by both people while everyone's still relaxed about it. The trouble is that writing one up and getting it "officially" signed has always felt heavier than the favor warrants.
It shouldn't. A simple, dated, signed record is the kindest thing you can do for a loan between people who care about each other.
How sign.pink solves it
A dated, defensible record
Every signature is time-stamped, so the note isn't just words — it's a record that shows exactly when both people agreed to the terms.
Tamper-evident from the start
If a page or value were altered after signing, the audit trail would show it. The version everyone signed is the version that stands.
Both signatures, one PDF
You and the borrower each sign; both of you walk away with the same finished, dated document to keep.
Signed on a phone in minutes
No account, no app, no awkward printer hunt. They tap the link, read the terms, and sign — and it's handled.
Put an IOU on the record in four steps
- Write up a short promissory note — the amount, the repayment date, and any interest or terms — or start from a saved template.
- Add signature and date fields for both of you, then enter the borrower's name and email.
- Send the link. The borrower reviews the terms and signs on their phone; you sign too.
- You both keep the finished, dated, tamper-evident PDF with the audit trail attached.
Will the note actually hold up? Yes. A promissory note signed electronically is enforceable under ESIGN and UETA in all 50 states, and the tamper-evident, time-stamped audit trail is what makes it defensible if the terms are ever questioned. See why e-signatures are legally binding for the details. For larger or more complex loans, it's always worth a quick word with an attorney.
