Quick Answer
When you lend money to a small business — even one owned by a friend or family member — you need more than a handshake and a good feeling. To protect yourself, you need a properly drafted promissory note, a security agreement covering collateral, a UCC financing statement filed with the Pennsylvania Department of State, and in most cases, a personal guarantee from the business owner. Without these documents, you are an unsecured creditor — and if the business fails, you will likely get nothing.
Why Informal Business Loans Almost Always Go Wrong
Every month I talk to someone who lent money to small businesses — a relative's new restaurant, a friend's contracting company, a colleague's startup — based on a relationship, a verbal promise, or a quickly typed email. When the business succeeds, those loans usually get repaid and everyone moves on. Most of the time these conversations involve a struggling business — and a significant percentage of small businesses do — and the informal lender is either not getting paid or, more often, not having their calls returned by that friend or colleague they lent money to.
Here is why: when a business fails or faces financial distress, its creditors are usually paid in a order of priority. The government gets paid first – payroll taxes, sales tax, etc. Creditors who are crucial to continued operation of the business, such as suppliers, often get paid next. Secured creditors — those with properly documented loans backed by collateral and structured payment arrangements (think lenders with auto payments or franchisors) — are often at the front of the payment line. Unsecured creditors — those with no collateral, no filed notices, or improperly documented loans — are paid last, typically receiving pennies on the dollar in bankruptcy, or nothing at all. Then there’s the typical investor with an informal or poorly documented business loan. You. Are. Last.
If you lend $50,000 to a business with a handshake, a text message, or even a signed IOU, you are almost certainly an unsecured creditor. If that business later borrows money from a bank that properly secures its loan, the bank will be paid before you — even if you lent your money first.
The solution is not complicated. It requires four specific legal tools used together: a promissory note, a security agreement, a UCC financing statement, and a personal guarantee. Each serves a different purpose, and all four working together give you the strongest possible legal position as a private lender.
The Promissory Note: Your Foundation Document
A promissory note is a written, signed promise by the borrower to repay a specific sum of money under specific terms. It is the foundational document of any business loan and is legally enforceable as a standalone instrument under Pennsylvania law.
What a Promissory Note Must Include
A promissory note for a business loan should contain, at minimum:
Principal amount — the exact dollar amount being lent
Interest rate — stated as an annual percentage rate (APR); if no interest is charged, the note should state that explicitly to avoid IRS imputed interest issues
Repayment schedule — when payments are due (monthly, quarterly, a lump sum at maturity, etc.)
Maturity date — the date by which the entire loan must be repaid
Default provisions — what constitutes a default (missed payment, insolvency, dissolution of the business) and what rights the lender has upon default
Acceleration clause — a provision allowing the lender to declare the entire remaining balance due immediately upon default, rather than waiting for each missed payment
Governing law — the state whose laws govern the note (Pennsylvania, for loans involving Pennsylvania businesses)
Signatures — signed by an authorized representative of the borrowing business, with their title and authority to bind the entity clearly identified
What a Promissory Note Does NOT Do
A promissory note by itself establishes the debt and gives you the right to sue for repayment — but it does not give you priority over other creditors, and it does not give you any claim to specific business assets if the borrower defaults. For those protections, you need a security agreement and a UCC filing.
Interest Rate Considerations
Pennsylvania's usury laws limit the interest rate that can be charged on certain types of loans. For business loans between private parties, the legal landscape is more permissive than for consumer loans, but the rate should be commercially reasonable and documented clearly. Additionally, the IRS has Applicable Federal Rate (AFR) rules that require minimum interest rates on certain loans to prevent the IRS from treating the arrangement as a gift. If you lend more than $10,000 with no interest or below-AFR interest, the IRS may impute interest income to you regardless of what you actually receive. Consult a tax advisor about structuring the rate correctly.
Security Agreements: Getting Collateral Behind Your Loan
A security agreement is a contract in which the borrower (the "debtor") grants the lender (the "secured party") a lien on specific property — called "collateral" — to secure repayment of the loan. If the borrower defaults, the secured party has the legal right to repossess and sell the collateral to recover what is owed.
Security agreements are governed in Pennsylvania — and in every other U.S. state — by Article 9 of the Uniform Commercial Code (UCC), which provides a standardized framework for secured transactions involving personal property.
What Can Be Used as Collateral?
Under Article 9 of the UCC, a security interest can be granted in virtually any type of personal property the business owns, including:
Type of Collateral | Examples |
Accounts receivable | Money owed to the business by its customers |
Inventory | Goods held for sale or use in operations |
Equipment | Machinery, vehicles, computers, tools |
Fixtures | Property attached to real estate but treated as personal property |
General intangibles | Intellectual property, goodwill, software, contract rights |
Deposit accounts | Business bank accounts (requires control agreement with the bank) |
Investment property | Stocks, bonds, LLC membership interests |
Instruments | Promissory notes payable to the business |
For most private business loans, the most practical and valuable collateral categories are accounts receivable, equipment, inventory, and general intangibles. Lending against a broad category — sometimes called an "all assets" lien — gives the lender the most comprehensive protection.
Reality Check
If the business has any type of bank loan, that lender is going to have a security interest in the business’ assets. Even if you get a security agreement, you’re likely behind the bank in line when things go south. Meaning you only get paid after the bank gets paid. The business assets may not be enough to fully pay the bank. But having a chance at collateral is better than no collateral at all. Before you lend to the business, you should ask whether the assets are already pledged as security for other debt obligations. Make in informed decision to lend.
What the Security Agreement Must Include
A properly drafted security agreement must:
Describe the collateral with reasonable specificity (or use "all assets" language for a blanket lien)
Identify both parties — the secured party (lender) and the debtor (business borrower)
Include a grant of security interest — the borrower's explicit agreement that the collateral secures the debt
Be authenticated (signed) by the debtor
Reference the underlying obligation — typically the promissory note it secures
A security agreement alone is not enough. To be enforceable against third parties — including other creditors and a bankruptcy trustee — you must perfect your security interest, which in most cases means filing a UCC financing statement.
UCC Financing Statements: How You Perfect Your Security Interest
Perfection is the legal process by which a secured creditor gives public notice of its lien to the world. A perfected security interest has priority over unperfected interests and, in most cases, over interests that were perfected later. Perfection is what makes the difference between being a secured creditor with real collateral protection and being a creditor who merely has a security agreement on paper.
For most types of collateral covered by Article 9, perfection is accomplished by filing a UCC-1 Financing Statement with the appropriate state office.
Filing a UCC-1 in Pennsylvania
In Pennsylvania, UCC-1 financing statements are filed with the Pennsylvania Department of State. The filing must include:
The debtor's correct legal name (exactly as registered with the state, for a business entity)
The secured party's name and address
A description of the collateral
A UCC-1 can be filed online through the Pennsylvania Department of State's filing portal. The filing fee is modest. Once filed, the financing statement is effective for five years and must be renewed (by filing a UCC-3 continuation statement) before it lapses.
Why the Debtor's Name Must Be Exact
One of the most consequential and underappreciated rules in UCC Article 9 is the requirement that the debtor's name on the financing statement match the debtor's correct legal name exactly. For registered entities — LLCs, corporations, LPs — this means the name as it appears in the entity's most recent publicly filed organizational document. A filing against "ABC Restaurant" when the entity's legal name is "ABC Restaurant LLC" may be seriously misleading and therefore legally ineffective under Pennsylvania's UCC rules. Courts have invalidated UCC filings over seemingly minor name discrepancies.
Priority: First to File, First in Line
Under the UCC, priority among competing security interests in the same collateral is generally determined by who filed first. This is called the "first to file or perfect" rule. If a business borrows from you in January and you file a UCC-1 in February, and then the business borrows from a bank in March and the bank files in March, you have priority over the bank in the collateral — even if the bank's loan is larger. But if you never file, or you file after the bank, the bank has priority over you regardless of when you made your loan.
This is why filing promptly — and correctly — is essential.
Personal Guarantees: Going Beyond the Business
A personal guarantee is a written agreement in which an individual — typically the business owner or owners — personally promises to repay the business's debt if the business fails to do so. A personal guarantee pierces the liability shield of the LLC or corporation and makes the guarantor personally responsible for the debt.
Without a personal guarantee, your recourse if the business defaults is limited to the business's assets — and if the business is insolvent, there may be nothing left to collect. With a personal guarantee, you can pursue the individual owner's personal assets: bank accounts, real estate, investment accounts, and other property.
Types of Personal Guarantees
Unlimited personal guarantee — the guarantor is personally liable for the entire amount of the debt, plus interest, fees, and collection costs. This is the most protective form for the lender.
Limited personal guarantee — the guarantor's liability is capped at a specific dollar amount or percentage of the debt. This is a negotiated concession that limits the lender's protection but may be necessary to get a deal done.
Continuing guarantee — covers not just the current loan but any future obligations the business incurs to the lender, up to a stated limit. Used when the lending relationship is ongoing.
Guaranty of payment vs. guaranty of collection — a guaranty of payment allows the lender to go directly after the guarantor upon default without first exhausting remedies against the business. A guaranty of collection requires the lender to first attempt to collect from the business before pursuing the guarantor. Always insist on a guaranty of payment.
What a Personal Guarantee Should Include
Identification of the guarantor (individual name, not business name)
The specific debt being guaranteed
Whether the guarantee is limited or unlimited
A waiver of defenses — the guarantor agrees not to raise certain defenses (notice of default, demand for payment, etc.) that might otherwise delay enforcement
A waiver of subrogation rights (in some circumstances)
A provision making the guarantee enforceable even if the underlying debt is modified
Governing law and dispute resolution provisions
The guarantor's signature (and ideally their spouse's, in appropriate circumstances — see Pennsylvania-specific notes below)
Getting a Spousal Signature
In Pennsylvania, a personal guarantee signed only by one spouse may not reach marital property held as tenancy by the entireties — a form of joint ownership between spouses that is protected from the individual debts of either spouse alone. If the business owner's most significant assets (typically the family home) are held in tenancy by the entireties, a guarantee signed only by the business owner may be uncollectable against those assets. To reach entireties property, both spouses must sign the guarantee. This is a frequently overlooked point that can dramatically reduce the practical value of an otherwise well-drafted guarantee.
Real-World Examples of What Goes Wrong
Example 1: The Friendly Loan That Became an Unsecured Debt
David lends $80,000 to his brother-in-law's start-up plumbing business. They sign a simple IOU and agree the money will be paid back "when the business takes off." Two years later, the business takes out a $150,000 SBA loan, properly documented and secured by all business assets with a UCC-1 filing. The business subsequently fails. The SBAlender, as the senior secured creditor, is first in line for the equipment and receivables. David, as an unsecured creditor with only a handwritten IOU, receives bupkis.
Example 2: The UCC Filing That Was Never Made
Susan lends $60,000 to a catering company owned by a longtime friend. A local attorney drafts a promissory note and security agreement granting Susan a lien on all equipment and accounts receivable. But no UCC-1 is ever filed with the Pennsylvania Department of State. When the company files for Chapter 7 bankruptcy two years later, the bankruptcy trustee — who has the legal powers of a hypothetical lien creditor — takes priority over Susan's unperfected security interest. Susan's lien is avoided in bankruptcy and she is treated as an unsecured creditor, recovering less than ten cents on the dollar.
Example 3: The Wrong Name on the UCC Filing
A private lender who is a huge craft beer fan loans $45,000 to micro-brewery. A UCC-1 is filed, but it lists the debtor as "Three Rivers Brewing" — the trade name — rather than the entity's legal name, "Three Rivers Brewing and Distilling, LLC," as registered with the Pennsylvania Department of State. When the business defaults and a dispute arises over priority with a subsequent lender who filed correctly, the court finds the first lender's UCC filing fatally defective due to the name error. The second lender, who filed later but correctly, takes priority.
Example 4: The Personal Guarantee That Didn't Reach the House
Steve makes a $100,000 loan to friend with a restaurant whose fire suppression system broke and can’t afford to fix. The managing member of the business signs a personal guarantee. When the restaurant fails and Steve seeks to collect from the guarantor personally, he learns that the guarantor's primary asset — a home worth $400,000 — is titled in both spouses' names as tenants by the entireties. Because only the business owner signed the guarantee, and not the spouse, the entireties property is protected from the Steve's claim. Steve’s recovery is limited to accounts and assets held solely in the guarantor's name, which are minimal.
When to Call a Business Attorney
You should consult one of Fiffik Law Group’s experienced Pennsylvania business attorneys before you hand over the cash to the business:
The loan is $10,000 or more (the cost of drafting proper documents is a fraction of what you stand to lose)
You are unsure whether the business has existing liens on its assets
The business owner is unwilling to sign a guarantee or provide collateral
The collateral includes real estate, titled vehicles, or deposit accounts
You are lending to a family member and want to ensure the loan is legally enforceable
You should consult an attorney after the loan is made if:
The borrower has missed payments or communicated financial distress
The borrower isn’t returning your calls and is ghosting your texts
You drive by the business and there’s a “closed” or “going out of business sale” sign in the window
You are unsure whether the janky loan documents you pulled down from the internet are enforceable
The business has filed for bankruptcy or is threatening to do so
They sold the flipper property and you never got paid
The cost of drafting loan documents can be paid directly from the loan proceeds, thus the borrower is paying to have you protected.
The Bottom Line
Lending money to a small business is not inherently reckless — but lending without proper documentation is. The four tools described in this post — a promissory note, a security agreement, a UCC-1 financing statement, and a personal guarantee — work together as a system. Each addresses a different vulnerability. Together, they transform you from a handshake creditor with no legal footing into a secured lender with priority rights, enforceable collateral claims, and personal recourse against the owner.
The documentation is not expensive. The attorney's fees to prepare these four documents properly are typically a small percentage of the loan amount, and they can mean the difference between recovering your money and writing it off entirely.
If you are going to lend money to a business, do it right from the start. The time to protect yourself is before the money changes hands — not after things go wrong.
Frequently Asked Questions
1. Do I really need all four documents — note, security agreement, UCC filing, and guarantee?
Uh, yeah! You need all four for maximum protection. The promissory note establishes the debt. The security agreement gives you a lien on collateral. The UCC filing makes that lien effective against third parties and in bankruptcy. The personal guarantee gives you recourse against the owner individually. Omitting any one of them leaves a significant gap in your protection. Many private lenders skip the UCC filing because it seems technical — but it is often the most important step of all.
2. What if the business owner says they can't give me collateral?
That is a negotiating position, not a legal fact. If the business has assets — equipment, accounts receivable, inventory — those assets can generally serve as collateral regardless of what the owner prefers. If the business has no assets worth securing, that itself is important information about the risk of the loan. A business owner who is unwilling to offer any collateral or guarantee is asking you to take all the risk while they retain control. You should factor that into your decision whether to lend.
3. Can I lend money to a business without charging interest?
Yes, but you should document the zero-interest terms explicitly in the note, and you should consult a tax advisor. The IRS has imputed interest rules (under IRC Section 7872) that may treat a below-market or interest-free loan as partially a gift, with tax consequences for both the lender and borrower depending on the loan amount and relationship between the parties.
4. What happens to my loan if the business files for bankruptcy?
You’re probably screwed – but not necessarily. A lot depends on whether your loan is secured or unsecured, and whether your security interest is properly perfected. A properly perfected secured creditor generally has the right to relief from the automatic stay to repossess and sell collateral, or to have the value of their lien recognized in the bankruptcy plan. An unsecured creditor — or a secured creditor whose interest was not properly perfected before bankruptcy — may have their lien avoided by the bankruptcy trustee entirely. This is one of the most important reasons to file your UCC-1 promptly and correctly.
5. Should I record a mortgage on the owner's real estate instead of filing a UCC?
A mortgage on real estate is a different and additional type of security, not a substitute for a UCC filing on business personal property. If the business owner is willing to grant a mortgage on real estate as additional collateral, that can significantly strengthen your position — but it requires a separate mortgage document and recording in the county recorder of deeds office where the property is located. It does not replace the need to perfect your security interest in business personal property through a UCC filing.
6. What if someone else already has a UCC filing on the business's assets?
Search the Pennsylvania UCC records before you lend. If a prior lender — a bank, an SBA lender, or another private party — already has a filed UCC-1 covering the same collateral, they have priority over you. You will be in second position on that collateral. This doesn't necessarily mean you shouldn't lend, but it changes your risk profile significantly, and you should understand the existing debt load before you commit.
7. How do I search UCC filings in Pennsylvania before I lend?
The Pennsylvania Department of State provides an online UCC search portal at dos.pa.gov. You can search by the debtor's name and see all active financing statements filed against that entity. Always conduct a UCC search — and a judgment and lien search — before finalizing any business loan.
