INSTRUCTION SHEET

Promissory Note with Optional Guaranty

Puerto Rico
Form PR-GEN-04 · Version 2026.2 · Last reviewed November 2026
READ THIS FIRST — This Instruction Sheet accompanies Form PR-GEN-04. It explains, in plain language, what the form does, how to complete each yellow field, and when the form is not enough for your situation. It is not legal advice. Keystone Legal Forms, the publisher, is not a law firm, and no attorney-client relationship is created by your purchase or use of this form. Puerto Rico regulates the interest that may be charged on a loan: read "The interest rate" in Section 3 before choosing a rate, and if anything in the section "When this form is not enough" applies to you, consult a Puerto Rico attorney before signing.
1. What this form does and who it is for

A promissory note (pagaré) is the borrower's written, unconditional promise to repay a loan on stated terms. It is the document that turns a handshake loan — to a relative starting a business, between partners, from an owner to his or her own company, or to a customer paying in installments — into an enforceable obligation that can be collected in court without having to prove the underlying deal. This form contains the note, an amortization table, and an optional personal guaranty by a third person (fianza) for use when the borrower is a company or the lender wants a second signature.

Use this form if: the lender is an individual or a business that is not a bank or licensed lender; the borrower is an individual or a business; the loan is a fixed amount repaid in installments, interest-only with a balloon, or in a single payment; and the loan is unsecured or is secured by a separate security agreement.

Use a different form if: the loan is secured by real estate (a mortgage note must be made before a notary as a public instrument and recorded — see Section 5); the lender is in the business of lending (licensing and consumer-credit rules apply); the borrower is a consumer and the loan is for personal purposes with a lender that is a business (consumer credit disclosures apply); or the "loan" is really an investment that should be documented as equity or a convertible instrument.

2. How to complete the form

• Work in Microsoft Word (or any program that opens .docx files). Every field appears in yellow highlight inside square brackets, for example [MAKER NAME]. Replace the whole bracket — including the brackets themselves — with your information, and remove the yellow highlight (select the text, then Home → Text Highlight Color → No Color).

• Some fields offer choices, written as "OPTION A" OR "OPTION B", or begin with the word TYPE followed by the alternatives. Pick one, type that text in place of the entire bracket, and delete the alternatives.

• The Key Terms table carries every number; the note's text refers to it. Complete the Key Terms, then Schedule A, then the Guaranty if the Key Terms call for one; otherwise delete the Guaranty page. Delete the cover page before signing.

• Use the search function (Ctrl+F) to search for an opening square bracket when you are done. Dates: write them in full ("March 3, 2026").

Field-by-field guide

Questions

What file do I get?

A zip with the Puerto Rico edition as Word (.docx) files in English and Spanish, plus the Instruction Sheet. Open in Microsoft Word, Google Docs or LibreOffice.

How do I complete it?

Open the Instruction Sheet first. Replace each yellow [BRACKETED FIELD] with your information, delete the options you do not use, delete the cover page, then print or e-sign.

Can I reuse it?

Yes. The license covers your own business and every company you own; it does not allow resale of the template itself.

Do I need a notary or a lawyer?

The Instruction Sheet says when a signature needs a notary and lists the situations where the form is not enough and an attorney should review it.
