Quick answer

An heir waives an inheritance by signing a public instrument — typically a notarized Deed of Waiver or Renunciation, or a waiver clause inside a Deed of Extrajudicial Settlement — or, if the estate is under court settlement, by filing a written waiver with that court. A waiver made in favor of everyone equally is generally free of donor’s tax; a waiver naming one specific heir is treated as a donation and taxed accordingly.

Waiving an inheritance is a more formal act than most people expect. Under the Civil Code, it is not something you can do by simply telling your siblings you do not want your share, or by staying away from the family lawyer’s office. It has to be reduced to writing in one of the forms the law recognizes, it has tax consequences that differ depending on how you word it, and once validly made, it generally cannot be undone.

What the Law Means by “Waiving” an Inheritance

In succession law this act is called repudiation. Article 1042 of the Civil Code provides that the effects of accepting or repudiating an inheritance retroact to the moment of the decedent’s death — meaning that once you validly repudiate, the law treats you as if you never owned that share at any point, not even for an instant. That single rule explains almost everything else about how a waiver has to be done: because it erases your ownership retroactively, the law insists on clear proof that you actually meant to give it up.

Two things must already be true before a waiver is even possible. First, the person you are inheriting from must already be dead — you cannot waive a future inheritance from someone who is still alive, no matter how certain that inheritance seems. Second, your right to the inheritance must be free of doubt (for example, an ongoing dispute over whether you are actually a recognized heir would need to be resolved first).

General Waiver vs. Waiver in Favor of One Heir

This distinction matters more than almost anything else in the process, because it changes both the paperwork and the tax bill.

Many families choose a general waiver precisely to avoid triggering a second layer of tax, especially when the intent is simply to let the remaining heirs divide the property without one sibling formally receiving an extra gift from another.

Waiver vs. Sale or Assignment of Hereditary Rights

Heirs sometimes use the word “waiver” loosely to describe something that is legally a different transaction: a sale or assignment of hereditary rights for a price. A true waiver or repudiation is gratuitous — the heir receives nothing in return, and Article 1042’s retroactive effect treats the waiving heir as though the inheritance never passed through their hands at all. A sale or assignment of hereditary rights, by contrast, is onerous: one heir transfers an undivided share to a co-heir or to an outsider in exchange for payment, and because value changed hands, the transaction is analyzed as a sale rather than a repudiation, carrying its own tax treatment separate from donor’s tax. The two documents can look similar on the page — both are typically notarized instruments signed by an heir giving up a share — but which one a family actually needs depends on whether money or other consideration is changing hands. Mislabeling a paid transfer as a “waiver” when it was really a sale, or the reverse, is one of the more common ways a family ends up with a document that does not match what the BIR later determines actually happened, so it is worth being precise about which transaction is intended before the deed is drafted.

Step-by-Step: How to Execute a Valid Waiver

The exact steps depend on whether the estate is being settled extrajudicially (out of court, by agreement) or judicially (through a court proceeding, whether testate or intestate). Here is the general sequence for the far more common extrajudicial route:

If the estate is instead under a judicial settlement or probate proceeding, the waiver is filed as a pleading with the court hearing the case rather than executed as a private notarized deed, since Article 1051 expressly allows repudiation “by petition presented to the court having jurisdiction over the testamentary or intestate proceedings.”

Rules That Limit What You Can Waive

A handful of Civil Code principles constrain how a waiver can be structured:

What Happens to the Waived Share

When a compulsory heir validly repudiates, that heir is treated as though they had never been called to the inheritance for that share. Under the Civil Code’s rules on representation, an heir who repudiates generally cannot be represented by his or her own children as to the repudiated portion — the share instead accrues directly to the remaining co-heirs of the same degree, unless the applicable rules on substitution or representation in the particular succession provide otherwise. This is different from disinheritance or predecease, where representation by descendants may still apply, so anyone weighing a waiver with the intention of passing the benefit down to their own children should get that intention confirmed against the specific facts of the estate before signing anything.

A Few Practical Notes

Because a waiver is retroactive and largely irreversible, and because the choice between a general waiver and a waiver in favor of one heir changes the tax bill, it is worth having the deed reviewed before signing rather than after. Heirs frequently discover, only once the BIR assessment arrives, that what they intended as a simple family accommodation was read as a taxable donation because of how a single sentence in the deed was worded.

Frequently Asked Questions

Can I waive only part of my inheritance and keep the rest? As a rule, no. Acceptance or repudiation of an inheritance from a particular decedent must generally cover your entire share from that estate; you cannot accept part and reject part. You may, however, waive an inheritance from one relative while accepting one from another.

Is a waiver of inheritance the same as an extrajudicial settlement? No. An extrajudicial settlement is the agreement dividing the whole estate among the heirs; a waiver is a separate act by one heir giving up their share, which is often incorporated into that same settlement document but is legally distinct from it.

Do I need to go to court to waive my inheritance? Not if the estate is being settled extrajudicially — a notarized public instrument is enough. Court filing is required only if the waiver is made within an ongoing judicial or testate settlement proceeding.

Will I owe tax for waiving my share? A general waiver that simply lets your share accrue proportionally to your co-heirs is generally not treated as a taxable donation. A waiver naming one specific heir as the recipient is treated as a donation to that person and is subject to donor’s tax.
