In short
The declaration of heirs is the document legally establishing who the heirs are of a person who died without a will — without it, the decedent’s assets sit in limbo: the house cannot be transferred, nor the car, nor accounts closed. Since Act 282-1999 it has two concurrent routes and you choose: before a notary (any attorney-notary admitted by the Supreme Court), who examines the documents and records the declaration in an acta de notoriedad, or before the court, by petition. In the notarial route, the notary notifies the General Registry of Notarial Competencies at the start and end, and anyone can request a certification of the matter from the Office of Notarial Inspection with form OAT-1656 and $5 in stamps. The declaration is the first link in the inheritance chain: then come the Treasury release (estate) and the transfers of properties.
What is it?
It is the official determination of who inherits when there is no will. If the person left a will, the declaration does not apply: the heirs arise from the will itself (and to know whether one exists, you request the certification from the Registry of Wills). Act 282-1999 gave notaries competence over this procedure, concurrent with the courts’: the petitioner "shall have the option of presenting the matter before the notary or before the Court, as they deem convenient". In the notarial route the notary gathers and qualifies the documents, and if they conclude it proceeds, they record in a notarial act the requester’s name, the steps taken, the statements received, the documents examined and the declaration of facts and law — that is, who the heirs are. If they conclude it does not proceed, they return your documents, explain why, and you can try the judicial route.
Who can do it?
The procedure can be started by whoever is legitimated to do so — typically an heir or a person with an interest in the estate. It is used when the person died without a will (or the will was declared void). To prove it you need the negative certification from the Registry of Wills, plus the death certificate and evidence of family relationships: the children’s birth certificates, the marriage certificate if applicable. The notarial route can be handled by any person admitted by the Supreme Court as attorney and notary; the judicial one runs in the corresponding court.

Step by step
Step 1: Confirm there is no will
First of all, request the certification from the Registry of Wills: if a will exists, the inheritance runs through it and the declaration does not apply. That negative certification is also one of the documents the procedure requires. The ODIN certifications guide explains how to request it.
Step 2: Choose the route: notary or court
The law grants concurrent competence and the choice is yours. The notarial route exists precisely to decongest the courts and bring the procedure closer to people: the notary gathers the documents (you can provide them or they can obtain them), qualifies them, and if it proceeds executes the act with the declaration of heirs. The judicial route remains available, and it is the natural path if the notary concluded the case does not proceed in their forum or if a dispute arises between the parties.
Step 3: In the notarial route: the matter is registered
The notary notifies the start of their intervention to the General Registry of Notarial Competencies within 3 working days of signing the contract, and notifies their final determination within 72 hours. They prepare a file with the sworn statements, examined documents and notifications to interested parties. That registry is your protection: anyone can later verify the matter was processed.
Step 4: Request the certification if you need it
To evidence the matter before banks, agencies or the Property Registry, the Office of Notarial Inspection issues certifications from the Registry of Non-Contentious Matters. It is requested with form OAT-1656, accompanied by $5.00 in internal revenue stamps, by mail (PO Box 190860, San Juan, PR 00919-0860), by email to asuntosnocontenciosos@poderjudicial.pr, or by calling (787) 763-8816 for guidance. You can pick it up in person or receive it by mail if you include a pre-addressed stamped envelope.
Step 5: Follow the inheritance chain
The declaration says who inherits; it transfers nothing by itself. With it in hand, the usual next step is the Treasury estate release, and then the concrete transfers: the vehicle title, the bank account, power and water, and the property registration. Several of those steps have their own PRFácil guide.

How long it takes
What to do if something goes wrong
If the notary ceases the procedure — because documentation is missing, a dispute arose among interested parties, or they concluded it does not proceed — they must return your documents and explain why, and they notify the Registry. That does not kill your case: the judicial route remains open. If a will appears midway, the procedure changes nature: the inheritance runs through the will. If there is real disagreement among potential heirs (someone denies a tie, there are unrecognized children), the matter becomes contentious and belongs to the court. And do not forget the children from every marriage and outside marriage: omitting an heir from the request is the seed of a later lawsuit.
Common mistakes
- Not knowing the notarial route exists: since Act 282-1999 the declaration can be processed before a notary, and the choice of route belongs to the petitioner.
- Starting without the negative certification from the Registry of Wills: it is the evidence there is no will, and the procedure does not move without it.
- Omitting children from prior marriages or outside marriage: every potential heir counts, including those who died before.
- Believing the declaration transfers the assets: it only declares who inherits; the transfers and Treasury release come after.
- Sending the OAT-1656 request without the $5.00 in stamps: the Office does not receive it without the stamp.
- Forcing the notarial route when heirs are in dispute: if a controversy arises, the matter belongs to the court.
Frequently asked questions
How much does a declaration of heirs cost?
It depends on the route and the case. Notary fees are agreed in a professional services contract and there is no published official rate; the judicial route carries court fees (see the fees guide). The only fixed price in the sources we read is the certification from the Registry of Non-Contentious Matters: $5.00 in stamps.
Who inherits when there is no will?
The order of heirs is set by the Civil Code, and applying it to your specific family is exactly the declaration’s job: that is why the notary or court examine the certificates and declare the facts and the law. We do not answer the order here because we did not read that source for this guide — and because the right answer depends on your case: who was alive, who died first, who was married to whom.
Is the notary’s act worth the same as the court order?
The notarial competence of Act 282-1999 is concurrent with the courts’ for these matters: it is a complete legal route, with mandatory notification to the General Registry of Notarial Competencies and a formal file. The Office of Notarial Inspection certifies processed matters, and that certification is what you present wherever asked.
What about letters testamentary?
The issuance of letters testamentary is another matter form OAT-1656 can certify, and it applies when there IS a will and the executor or administrator needs accreditation. It is a sibling procedure to the declaration, for the opposite scenario.
