You can write a private loan agreement yourself. Free templates help with the layout. They don't know your state's interest cap or your collateral rules. No federal loan template replaces state contract law.

A loan agreement is just the written record. It names who borrowed what, when repayment happens, and what happens if it doesn't. Those answers belong in one document. State law fills in the rest.

Federal law handles one narrow issue. Can a signature or record lose legal effect only because it's electronic? Under the E-Sign Act, usually no for transactions in or affecting interstate commerce. That general rule doesn't bless every template. State rules on interest, notarization, witnesses, and collateral still apply.

What a Loan Agreement Can and Cannot Do

A working agreement handles three things: it shows the money moved, states how repayment works, and maps out what happens when someone breaks the deal. Draft it before money moves, not after a payment is late.

Paperwork won't fix a deal that breaks state law. If your rate violates state usury law, a tidy PDF is still a problem. A car can secure the loan, but only if you perfect the interest. Miss that step and another creditor may beat you to the asset. A contract is a tool, not armor.

Promissory Note or Loan Agreement?

Reach for a loan agreement if the deal has interest, installments, collateral, a guarantor, or more than a few hundred dollars. A promissory note can cover a simple loan from a family member. It also leaves more room for disagreement.

To be honest, neither form wins by default. Match the paperwork to the risk. A $500 loan to a sibling may need only a short note and a payment app record. A $20,000 loan against a truck needs more. Skip the paperwork because the borrower is family, and you are not saving time. You are moving the argument to a later date, when everyone is angrier and the details are fuzzier.

The Terms That Matter Most

Here's a drafting order that keeps you from skipping the clauses people fight about later.

1. Use full legal names for everyone, spelled the same way everywhere. Add addresses and contact details.
2. State the principal. Write "$10,000" and spell out the currency. If the money is already owed from something else, say that.
3. Define interest. Give the annual rate and how it compounds. If there is none, write "no interest" instead of leaving a blank.
4. Set the repayment schedule. Include the first due date, the amount, the frequency, and the payment method.
5. Explain what counts as default. A missed payment, a late payment, or bankruptcy can all count. Be specific.
6. Add an acceleration clause if you want one. It lets the lender demand the full balance after certain defaults.
7. Cover late fees and prepayment. Say whether early payoff is allowed and whether any penalty applies.
8. Describe collateral if the loan is secured. "My car" is weak. Use the VIN, year, make, model, and lien details.
9. Choose governing law and venue. Name the state whose law applies and where a dispute would be heard.
10. Pick dispute resolution. Arbitration, mediation, or court. Each has tradeoffs.
11. Sign and date it. Keep a copy for each party.

That is the skeleton. The rest is customization.

Interest and Fees Are State-Law Questions

Interest is where DIY loans go wrong most often. Every state has its own usury limits. The cap can depend on who is lending, how much is loaned, and whether the loan is personal or business. A rate that is fine in one state may be unenforceable in another.

Late fees are separate from interest in many states. Some states cap them. Others treat a high late fee as disguised interest or allow fees only after a specific grace period.

Thing is, you can't grab a number from a random template and assume it's legal where you live. Check your state statute or ask a local attorney. For a private loan, one hour of legal review can cost less than one failed collection attempt. One failed collection attempt can burn a weekend you won't get back.

Secured Loans Need More Than a Signature

Pledging property sounds simple until you get to the legal steps.

An unsecured loan rests on the borrower's promise to repay, so if the borrower has no money, collection gets harder. A secured loan adds a legal claim against specific property, but a missed filing or a bad collateral description can weaken that claim.

For secured transactions, UCC Article 9 usually governs how a security interest is created and perfected. In many cases, perfection requires a UCC-1 financing statement filed with the right state office. Vehicles, real estate, and business assets can have their own rules. Holding a title or a signed agreement often is not enough. If the collateral is valuable, get the filing checked before you fund the loan.

E-Signatures and Notarization

Electronic signatures are valid for many loan contracts in the U.S. The E-Sign Act says a signature, contract, or record cannot be denied legal effect solely because it is electronic. That is the general rule.

Consumer disclosures have extra consent rules. The FDIC's E-Sign guidance explains that consumers may need to consent electronically and receive notices about paper records. Private loans between individuals don't always trigger those rules. A business lender might.

Notarization is a different question. There is no federal notary requirement for private loan agreements. Your state may require notarization or witnesses for certain loans, especially around real estate or large amounts. Remote online notarization is available in many states, but the rules vary. Turns out, a notary does not make a bad contract good. It mainly strengthens evidence that the signatures are real.

Mistakes That Lead to Court

Most disputes do not start with fraud. They start with fuzzy terms. One loan says the payment is $400 but the math points to $385. Another has no written rule for late payments. A third describes collateral as "all my stuff." Then someone fills in a blank interest rate later, or a guarantor never signs, or an oral side promise never makes it into the document. Each one gives the other side something to argue about. Arguing is expensive.

Fix them before signing. If you change a term later, write an amendment and have everyone sign it.

Taxes, Records, and Default

Interest you receive is generally taxable income to the lender. The borrower may be able to deduct interest only in limited situations, such as certain business or home loans. Keep payment records, bank statements, and written amendments. If a debt is forgiven, tax rules can apply to the forgiven amount. Use IRS guidance or a tax professional for your situation.

If the borrower stops paying, read the default and acceleration clauses first. Then send a written demand and keep proof of delivery. Small claims court may be an option for smaller amounts, but dollar limits and procedures vary by state. For secured loans, repossession and foreclosure rules are strict. Taking property without following state law can create liability for the lender.

FAQ

Do I need a lawyer to draft a loan agreement? Not always. Simple loans between individuals can use a well-drafted template. Use a lawyer for large amounts, collateral, guarantors, cross-state parties, or anything you don't understand.

Are free loan templates legally binding? They can be if the parties sign and the terms comply with state law. A template is a starting point. It cannot tell you whether your interest rate or notarization rule is valid.

Does a private loan agreement need to be notarized? Not under federal law. Some states require notarization or witnesses for certain loans. Check your state rules before you rely on a signature alone.

Can I use an electronic signature? Usually yes for many loan contracts under the E-Sign Act. Some documents are excluded, and consumer disclosures have consent rules. If notarization is required, use a notary process your state accepts.

What interest rate can I charge? That depends on state usury law and the details of the loan. There is no single national cap. Check your state rules or ask a local attorney.

Before You Sign

Print the draft. Read the payment schedule out loud. Check the default clause, the collateral description, and the state law that applies. Sign two copies and store them where both sides can find them. General information only, not legal advice. For a loan that matters, get local advice before money changes hands.
