What Is a Secured Promissory Note and When You Need Collateral

The difference between a secured and an unsecured note is the difference between a lender who can take something back and one who can only sue and hope. Collateral changes everything about your odds of getting paid, and knowing when to require it is the core lender skill.

Balloon Payments on a Promissory Note: How They Work

A balloon payment keeps the monthly payments low by leaving a large lump sum due at the end. It can make a loan affordable month to month, but that final payment has ended more than a few borrowers who never planned for how they would actually cover it.

How to Calculate Interest on a Promissory Note

Interest is where promissory notes get confusing, because simple and compound interest produce very different totals, and amortized payments split each one between interest and principal in a way that surprises borrowers. Here is how the math actually works, in plain terms.

What Happens to a Promissory Note in Bankruptcy?

When someone who owes you on a promissory note files for bankruptcy, your loan does not simply vanish, but your odds of collecting hinge on one thing most private lenders never thought about: whether the note was secured. Unsecured lenders are often last in line and may get nothing.

Is a Promissory Note Legally Binding in Florida?

Yes, a promissory note is enforceable in Florida when it is properly written, and Florida courts enforce them routinely. But properly written is doing real work in that sentence. A note that misses a basic requirement, or charges illegal interest, can be weakened or thrown out entirely.

What Interest Rate Can You Legally Charge? Usury Limits Explained

Charging interest on a loan is legal and often sensible, but every state sets a ceiling, and crossing it can do far more than void the interest. In some states it costs you the right to collect the loan at all. Here is how usury limits work and how to set a rate that actually holds up.

Does a Promissory Note Mean You Got the Loan?
Promissory Note Guides

Does a Promissory Note Mean You Got the Loan?

You applied for financing, went through the process, and now someone has handed you a promissory note to sign. Does that mean you're approved? Is signing the note the moment the loan becomes real, or is it just one more form in a process that could still fall through? The answer matters, because people sometimes treat signing a promissory note as a formality when it's actually one of the most consequential moments in the entire borrowing process...

Who Holds the Promissory Note While It's Being Repaid?

The note is signed, the money has changed hands, and now there's a physical document that represents the debt. Who keeps it? Does the lender hold it? The borrower? Both? A neutral third party? It's a practical question that doesn't get much attention until something goes wrong, and the answer has real implications for how the loan gets enforced, repaid, and ultimately closed out...

Can I Make My Own Promissory Note?

You need to document a loan and you're wondering whether you can just write the promissory note yourself, or whether this is one of those situations that requires a lawyer, a specific form, or some kind of official filing. The good news: yes, you can absolutely make your own promissory note, and for most loans it's the right approach. The catch is that "can" and "should do it carelessly" aren't the same thing.

Does a Promissory Note Need a Witness to Be Valid?

You've drafted the note, both parties are ready to sign, and someone asks whether you need a witness to make it official. Maybe a relative remembers signing important documents in front of witnesses. Maybe you've seen it in movies. The question is reasonable, and the answer surprises a lot of people: in nearly every case, no, a promissory note does not need a witness to be valid...

How to Write a Promissory Note for a $1,000 Loan to a Friend

A thousand dollars feels small until a friend doesn't pay it back. It's not enough to hire an attorney over, not enough to make small claims court feel obviously worth the trouble, but plenty enough to create lasting awkwardness every time you see that person. It's also exactly the amount where most people skip the documentation because it feels like overkill...

Do You Need a Promissory Note when Lending Money to your Parents?

Lending money to a parent is one of the more emotionally loaded financial situations an adult child can navigate. The power dynamic is reversed from what you grew up with. The person who used to take care of you now needs your help, and asking them to sign paperwork feels like rubbing their nose in it. So most people skip the documentation, hand over the money, and tell themselves it will work out...

How to Write a Promissory Note for a $20,000 Business Loan

Twenty thousand dollars is a meaningful number in private business lending. It's large enough to require serious documentation, large enough to cause real financial damage if it doesn't come back, and right at the threshold where the difference between a well-drafted promissory note and a poorly drafted one starts to have significant legal consequences. It's also the kind of amount that often moves between people who know each other, a friend investing in a startup, a family member bridging a cash flow gap, a business partner covering payroll, which is exactly when documentation gets skipped and problems start...

You lent someone money. You have bank records showing the transfer. Now they're telling you, your family, or a judge that the money was a gift and they don't owe you anything.

You need a promissory note and you're wondering whether to spend $300 on an attorney or just write the thing yourself. It's a reasonable question, and the honest answer is that for most personal and family loans, you don't need a lawyer. But "you don't need a lawyer" and "you can write whatever you want" are not the same thing, and the gap between them is where most self-drafted notes fall apart...

Unsecured Promissory Notes: What Lenders Give Up and How to Protect Themselves

When you lend money without requiring collateral, you are making a bet on a person rather than a position. There is no car to repossess, no property to lien, no asset waiting in the background if the borrower stops paying. What you have is a signed promise and, if the note is properly drafted, the legal standing to pursue that promise through the courts...

How to Properly Loan Money to Your Child for a House Down Payment

Helping your child buy a home is one of the more meaningful financial gifts a parent can give. But when the help comes in the form of a loan rather than a gift, the way you document it matters more than most families realize.
