Standing surety: if it is not in writing, the suretyship is void

Last reviewed: September 10, 2026VerifiedPoder Judicial

In short

Three short articles decide who may stand surety and how it must be recorded. Article 1480 sets two requirements in a single sentence: any person with capacity to consent, who has sufficient property or solvency to satisfy the guaranteed obligation, may be a surety. Willingness is not enough: capacity is required, and backing is required. What the article does not say is who checks that backing, at what moment it is measured, or what happens to a suretyship signed by someone lacking it; this guide points that out and does not fill it in. Article 1481 closes in one line a door many assume is open: the surety cannot excuse its liability on the principal debtor’s incapacity. If you stood surety for someone who could not bind themselves, that incapacity does not get you out. And Article 1482 sets the form, also in one line: a suretyship not agreed in writing is null. There is no verbal suretyship under this chapter. That article reads best alongside the one opening the chapter, under which no undertaking not expressly agreed as suretyship is one, and neither is a letter of recommendation: between them they explain why a spoken promise to answer for someone creates no suretyship. The Code demands writing, but does not demand a public deed and names no form, fee or registry, and this guide adds none.

What is it?

They are Articles 1480, 1481 and 1482 of the Civil Code of 2020: who meets the conditions to be a surety, why the debtor’s incapacity does not free the surety, and why the suretyship must be in writing.

Who can do it?

Whoever is about to commit as a surety and the creditor accepting them, under a suretyship contract governed by the Puerto Rico Civil Code. This is not criminal bail.

Step by step

  1. Step 1: First requirement: capacity to consent

    Article 1480: any person with capacity to consent may be a surety. It is the same requirement the Code asks to bind oneself generally.

  2. Step 2: Second: sufficient property or solvency

    The same article joins it to the first: who has sufficient property or solvency to satisfy the guaranteed obligation. The measure is the obligation being guaranteed, not a fixed amount.

  3. Step 3: Who checks that: the article does not say

    It does not name who must verify it, at what moment it is measured, or what happens to a suretyship signed by someone without the backing. Nor does it say what happens if the surety becomes insolvent later. This guide points at the gap and does not fill it.

  4. Step 4: The debtor’s incapacity does not save you

    Article 1481, a single line: the surety cannot excuse its liability on the principal debtor’s incapacity. It is one of this chapter’s most surprising rules for someone who signs thinking that, if the debtor could not bind themselves, the suretyship falls with them.

  5. Step 5: In writing, or it does not hold

    Article 1482: a suretyship not agreed in writing is null. The Code itself declares the nullity; it is not an evidentiary requirement but one of validity.

  6. Step 6: Writing, yes; a public deed, it does not require

    The article asks that it be agreed in writing and stops there: it mentions no notary, public deed, form, fee or registry. This guide adds none of those requirements.

  7. Step 7: Why a spoken promise is no suretyship

    This article reads together with the one opening the chapter: there the Code says no undertaking not expressly agreed as such is a suretyship, nor is a letter of recommendation assuring a person’s probity and solvency. Between the writing requirement and the express-agreement one, saying out loud "I will answer for him" creates no suretyship under this chapter.

  8. Step 8: What these articles do not carry

    They do not say how much property is sufficient, do not describe how solvency is evidenced, fix no fee or concrete form, and do not say whether a surety who becomes insolvent must be replaced. None of that is here.

Where to do it

The suretyship is agreed between surety and creditor, in writing; the Code names no agency for this chapter and requires no registration. Disputes over the suretyship’s validity or the surety’s solvency are decided by the Court of First Instance.

What to do if something goes wrong

If your case is the bail a court sets in a criminal proceeding, or a construction payment bond, those are other subjects with their own guides on this site. If what you want is how far your cover reaches or whether you can get out, see the guides on the general provisions and on duration. If the question is whether the creditor can come straight at you, that is the beneficio de excusión, with its own guide. These three articles do not say how much property suffices, do not describe how solvency is evidenced, and do not require a public deed. MiPRFácil does not represent anyone in court and gives no legal advice.

Common mistakes

  • Accepting a verbal suretyship: Article 1482 declares it null if not agreed in writing.
  • Believing that if the debtor was incapable the suretyship falls: Article 1481 says the opposite.
  • Standing surety without sufficient property or solvency to satisfy the guaranteed obligation.
  • Measuring solvency against a fixed amount: the article measures it against the obligation guaranteed.
  • Accepting as surety someone without capacity to consent.
  • Assuming a public deed is needed: the article asks for writing and mentions no notary.
  • Confusing a letter of recommendation with a suretyship.
  • Signing a vague undertaking hoping it counts as suretyship: it must be expressly agreed as such.

Frequently asked questions

Is a suretyship we only agreed verbally valid?

No. Article 1482 says a suretyship not agreed in writing is null.

What is needed to be able to stand surety?

Article 1480 asks two things: capacity to consent, and sufficient property or solvency to satisfy the guaranteed obligation.

The debtor could not bind themselves. Does that free me?

No. Article 1481 says the surety cannot excuse its liability on the principal debtor’s incapacity.

Must I go to a notary to sign as surety?

Article 1482 requires the suretyship to be agreed in writing and mentions no notary or public deed. This guide adds no requirements the article does not carry.
