Understanding the legal line between borrower and guarantor is critical to enforceability, underwriting, and recovery.

Business-purpose lenders  must understand the legal distinction between a borrower on a promissory note and a guarantor on a guaranty. Accurately defining and documenting these roles is foundational to structuring enforceable, high-quality business-purpose loans. Lenders need clarity about who owes the debt versus who backs it, as this distinction drives both underwriting decisions and recovery strategies.

Although many states have similar or related laws, the analysis here focuses specifically on Ohio law. In other states, lenders should consult local counsel because enforcement mechanisms vary according to whether a state is judicial or non-judicial, counts included in the foreclosure complaint, timing, advertising requirements, and valuation rules. The Ohio framework examined here highlights the nature of each party’s obligations, the legal standards governing each, and the implications of those differences. The authors practice default law in numerous states and have focused this article on Ohio because many lenders choose to pursue the guarantor.

Business-purpose loans are typically extended to entities such as corporations or LLCs for commercial or investment purposes. They often require a personal guaranty from the shareholders, officers, members, and managers of the entities. These loans are not subject to the same consumer protection laws and constraints as residential loans, but they must still comply with Ohio’s usury limits for commercial loans. Usury limits laws are set at the state level and are put in place to cap the maximum interest rate a lender can charge on certain loans. Lenders often include default interest rate provisions in business loan agreements, which must be carefully reviewed to ensure compliance with applicable laws and regulations.

Again, focusing on Ohio, let’s review the definitions of these loan instruments.

A promissory note is a negotiable instrument that evidences an agreement to pay a monetary obligation. It is a written, signed, and unconditional promise to pay a fixed sum of money to order or to bearer. A borrower on a promissory note is directly obligated to make payments under the terms of the note. Failure to make payments constitutes a breach of the agreement.

A personal guaranty is a contract through which one party guarantees payment for debts incurred by another person or entity. The liability of a guarantor is secondary to that of the principal debtor and arises only upon the debtor’s default. A guarantor may guarantee either payment or collection. A guarantor of payment is obligated to pay the debt if the principal borrower defaults, without requiring the lender to exhaust remedies against the borrower. A guarantor of collection, however, is only obligated to pay after the lender has pursued remedies against the borrower and failed to collect. For the most part, a lender will want a guaranty of payment.

In summary, the distinctions between a promissory note and guaranty are that a promissory note is a separate and enforceable contract, while a guaranty is a distinct agreement that supports the primary obligation of the borrower. Ohio law views guaranties as contracts interpreted in the same manner as other contracts, emphasizing their distinct nature from the promissory note itself.

Understanding Borrowers and Guarantors

The primary distinction between a borrower on a promissory note and a guarantor lies in the nature of their obligations and the conditions under which liability arises.

A borrower on a promissory note is the principal obligor; this is typically the entity or LLC. The promissory note creates a direct and primary obligation to pay the debt as specified in the terms of the note. The lender can enforce the note directly against the borrower without any preconditions, except those set forth specifically in the note or possibly other loan documents such as a loan agreement. Failure to make payments constitutes a breach of the agreement, and the lender may seek remedies for this breach.

A guarantor, in contrast, is not the principal obligor but rather a secondary party who guaranty’s the debt of the borrower. The guarantor’s liability is contingent upon the default of the borrower. If the guaranty is one of payment, the guarantor is obligated to pay immediately upon the borrower’s default. If the guaranty is one of collection, the guarantor’s liability arises only after the lender has exhausted remedies against the borrower—and most likely the loan collateral—and has failed to fully collect the amount owed. Accordingly, it is imperative that lenders maintain a complete due diligence package that includes the guarantor’s personal information, such as residential address, Social Security number, and date of birth.

In summary, the key differences between borrowers and guarantor rest in the areas of liability, contractual obligation, and enforcement. The borrower on a promissory note is primarily liable, and the guarantor’s liability is secondary and contingent. A promissory note is a standalone contract, whereas a guaranty is a separate agreement that supports the primary obligation of the borrower. The lender can enforce a promissory note directly against the borrower. In contrast, enforcement of a guaranty depends on the type of guaranty (payment or collection) and may require the lender to exhaust remedies against the borrower first.

Usury and Interest Rates

Most loan instruments have both a current interest rate and a default interest rate. Ohio law governs the permissible interest rates that lenders may charge on loans, with specific provisions for different types of loans and borrowers.

In general regarding usury limits, Ohio law permits banks and other lenders to charge interest rates up to 25% per annum on loan contracts, provided the rate is agreed upon in writing. Certain exceptions apply, such as for loans payable on demand or in one installment, and for business loans.

Many loan agreements include provisions for higher interest rates while a loan is in default. These default rates must comply with Ohio’s usury laws and cannot exceed the maximum allowable rate under the agreement or applicable law. It is important to review the loan documents to ensure default interest rates are clearly defined and enforceable.

Under Ohio law, the distinction between a borrower on a promissory note and a guarantor on a personal guaranty is evidenced in the nature of their obligations and the conditions for enforcement. A borrower on a promissory note is directly and primarily liable for the debt, while a guarantor’s liability is secondary and contingent upon the borrower’s default. In addition, a promissory note and a guaranty are separate and distinct agreements, each governed by its own terms and conditions. Understanding and complying with Ohio’s usury laws and interest rate limits is essential for ensuring the enforceability of loan agreements, including promissory notes and guaranties.

Lender Takeaways

Although borrowers and guarantors may appear similar at face value, the legal implications are different. Borrowers are directly liable under the original contract, whereas guarantors provide secondary liability only upon borrower default. Lenders understanding the distinction between loan documents, parties, standard interest rate laws, etc., can structure agreements to ensure the successful enforcement of documents and avoid lengthy litigation in the future. Early communication with your law firm, once a default is imminent, is vital to ensuring the rights against the guaranty are properly preserved. If lenders have specific loan documents or scenarios they would like reviewed, reach out to legal counsel for advice.
