Personal Loans Between Individuals in Puerto Rico: How to Document and Collect Them Correctly

What is a personal loan between individuals and when does it make sense

A personal loan between individuals happens when one person lends money to another without going through a bank or credit union. It could be a parent lending to their child, two partners financing each other for a business, or close friends with a verbal agreement that gets formalized.

It makes sense when there is trust between the parties, when bank interest rates are prohibitive, or when you need flexibility that no bank offers. But trust alone does not protect the relationship or the money without documentation.

How to draft a valid promissory note in Puerto Rico

The basic document for a personal loan between individuals is the promissory note (pagare). A valid promissory note must include: the full names and addresses of both parties, the amount loaned, the interest rate, the payment schedule, the maturity date, and the signatures of both parties. Notarization is not required for validity, but it gives greater legal weight.

If the loan is between family members with no interest, document the agreement anyway. The IRS has rules about interest-free family loans above certain thresholds, and Hacienda may interpret an undocumented loan as a taxable gift.

Setting up a payment plan: terms, interest, and monthly payments

The payment plan defines how much the borrower pays each month, how many months the loan lasts, and how interest is calculated. For an amortized loan, each monthly payment covers part of the principal and part of the interest. This split changes every month as the balance decreases.

If you prefer something simpler, you can structure it as a simple-interest loan: the borrower pays fixed interest each month on the original balance and returns the principal at the end.

Regarding the interest rate: Puerto Rico does not have a universal usury cap for private loans between adults. A reasonable and documented rate protects the lender from Hacienda recharacterizing the loan.

What happens if the borrower stops paying

For smaller amounts (up to $5,000 in Puerto Rico), you can file a claim through the Small Claims process without needing a lawyer. The signed promissory note is your primary evidence. Without documentation, the claim is practically impossible to win.

For larger amounts, consider intermediate options before court: a formal letter documenting the default, renegotiation of the payment plan, or private mediation.

A well-drafted agreement discourages default from the start. When there is a signed document with a clear payment schedule, both parties take the loan more seriously.

How to record and track payments to avoid conflicts

The number one cause of conflict in personal loans is disagreement over how much has been paid. Without records, both parties are right from their own perspective. Record each payment at the moment it occurs, with the date, amount, payment method, and the period it applies to.

Tools like Lend. are designed for exactly this purpose. You set up the loan once with the amount, rate, and schedule, and the system generates the amortization plan automatically. When the borrower pays via ATH Movil, the confirmation email is forwarded and the payment is recorded automatically.

Tax documentation: when it applies and when it does not

For a small interest-free loan between family members, there are most likely no direct tax implications beyond having the agreement documented. However, if the loan generates interest, the lender must report it as taxable income on their Puerto Rico income tax return.

If the loan exceeds certain IRS thresholds for family loans, federal law may require the lender to report imputed interest even if none was charged. Consulting with a CPA before formalizing the loan can save you surprises at year-end.

Concrete steps to get started correctly

First, put everything in writing before transferring the money. Draft a simple promissory note, sign it in front of two witnesses or before a notary, and keep a copy each.

Second, define how payments will be made. Bank transfers or ATH Movil leave an automatic digital trail. If payments will be in cash, use signed receipts. Third, keep an organized record from the first payment. If the loan spans several years, consider using a tracking tool like Lend. for an organized approach with clear history and an automatic payment plan.
