A registration is a decision, not a preference
All four states have adopted the same uniform act, and all four say that once a donor has made an anatomical gift, nobody else may revoke it. Florida puts it most bluntly: a family member, guardian, representative ad litem or health care surrogate may not modify, deny or prevent a donor's wish after the donor's death.
This is what the tick at the license counter actually did. It is why the question at the hospital is usually a notification rather than a request — and why it is worth deciding deliberately rather than in a queue.Source 3
The rule cuts both ways, which is the honest framing. A registration protects your decision to donate from a grieving relative who would refuse. It equally means a decision made quickly, years ago, is still operating. If you have ever ticked the box and are no longer sure, that is a reason to check the registry, not a reason to assume someone will ask.Source: A.R.S. §36-847 (Preclusive effect of anatomical gift, amendment or revocation) — Arizona State Legislature (opens in a new tab)•Source: California Health and Safety Code §7150.35 (Revised Uniform Anatomical Gift Act — bar on amendment or revocation by another) (opens in a new tab)•Source 4

Sahvelo gives information drawn from statutes, agency guidance and official forms. It is not legal advice for your particular situation. Terms & disclaimer.
What your family is actually asked
The family is not asked to consent to a registered donation. They are asked for a medical and social history — travel, medications, behavior relevant to infection risk — which the procurement organization needs in order to use the gift safely. That conversation is genuinely necessary and genuinely time-limited.
Where there is no registration and no document, the decision does pass to others, in a statutory order of priority that starts with a health care surrogate or spouse. That is the situation the whole topic exists to avoid, because it asks the people least able to think clearly to decide on your behalf within hours.
Tell the people who will be in the room. Not because they can overrule you — they cannot — but because a family confronted with a decision they did not know about experiences it as a second shock, and occasionally spends the window arguing about whether it is real.
How to record it so it is found
- Register with your state's donor registry. This is the record that hospitals actually check, and it is free.
- Take the designation on your driver's license or state ID as well, where the state offers it. It is the fastest signal in an emergency department.
- Say the same thing in your advance directive, so the document your family produces does not appear to contradict the registry.
- Tell your health care agent and at least one close family member what you have chosen and where it is recorded.
- If you want to limit the gift — organs but not tissue, transplant but not research — record the limitation rather than assuming it will be inferred.
Do not rely on a will alone. A will can make a gift, and Florida provides expressly that such a gift takes effect without waiting for probate — but nobody reads a will within the hours in which donation is decided. The registry is the operative record; the will is a backstop.Source: Fla. Stat. §765.514 (Making an anatomical gift) — The Florida Senate (opens in a new tab)•
Deciding against it
Declining is a legitimate decision, and it can be recorded with the same force as a gift. Each of these states provides for a refusal, and a recorded refusal spares the family being asked at all.
The failure mode here is silence. Someone who has decided against donation but recorded nothing leaves the decision with their next of kin under the statutory priority order — and there is no guarantee the person who ends up deciding knows what they wanted.
Religious objections are worth raising with your own community rather than assuming. Most major traditions permit donation, several actively encourage it, and a small number treat it as impermissible; the answer is specific enough that a general page should not supply it.
What is worth knowing before deciding
- Registering does not affect the care you receive. The clinicians treating you and the procurement organization are separate, and the doctor certifying death is barred from participating in the removal or transplant of a part.
- There is no upper age limit that rules a person out. Suitability is a medical judgment made at the time, not a birthday.
- Most medical conditions do not disqualify a donor. Deciding not to register on the assumption that you would be refused removes a decision you were entitled to make.
- An open-casket funeral remains possible. Recovery is a surgical procedure, and the statutes contemplate the body being returned for funeral services.
- Donation costs the family nothing. The costs of recovery are not charged to the estate.Source 3
How to make it official, by state
The binding effect is the same in all four states, which is why it sits in the body above. What differs is the route: which registry to use, and whether the statute itself names the driver's license designation as a way of making the gift.
How the statute says a gift is made
Registry, license, will, or a signed card
The answer in 4 states
-
Arizona
By registering on the state donor registry established by statute, in a will, by a signed donor card or other record, or — during a terminal illness — by a communication addressed to two adults, one of them a disinterested witness.Source 1 -
California
By authorizing the symbol on a driver's license or ID card, which is also included on the registry; directly through the Donate Life California registry website; in a will; by a signed donor card; or by a terminal-illness communication to two adults.Source 2 -
Florida
By signing a donor card, registering online with the donor registry, signifying intent on a driver license or ID card, or expressing the wish in a living will, another advance directive, or a will — which takes effect on death without waiting for probate.Source: Fla. Stat. §765.514 (Making an anatomical gift) — The Florida Senate (opens in a new tab)• -
New York
By a properly executed document of gift, or a document signed by the donor or made by a recorded message. Enrollment in the state registry is the practical route, and the statute treats donors aged sixteen and seventeen differently until they turn eighteen.Source 4
What happens to the license designation
The answer in 4 states
-
Arizona
The statute routes the decision through the donor registry rather than naming the license, so the registry entry is the record to check.Source 1 -
California
The license or ID symbol is a statutory method of making the gift, and the same authorization is included on the donor registry — so the two records are linked by design.Source 2 -
Florida
The license designation is a statutory method, and Florida provides expressly that revocation, suspension, expiry or cancellation of the license does not invalidate the gift.Source: Fla. Stat. §765.514 (Making an anatomical gift) — The Florida Senate (opens in a new tab)• -
New York
The statute frames the gift as a document of gift or a signed or recorded authorization rather than as a license marking, with the registry as the enrollment mechanism.Source 4
Who can undo it
The answer in 4 states
-
Arizona
Only the donor. Absent an express contrary indication by the donor, any other person is barred from making, amending or revoking the gift.Source: A.R.S. §36-847 (Preclusive effect of anatomical gift, amendment or revocation) — Arizona State Legislature (opens in a new tab)• -
California
Only the donor. Absent an express contrary indication by the donor, any other person is barred from making, amending or revoking the gift.Source: California Health and Safety Code §7150.35 (Revised Uniform Anatomical Gift Act — bar on amendment or revocation by another) (opens in a new tab)• -
Florida
Only the donor, and Florida names the excluded parties: a family member, guardian, representative ad litem or health care surrogate may not modify, deny or prevent the gift after death.Source 3 -
New York
Only the donor. An authorization may not be rescinded or amended by any other person except on a showing that the donor revoked it.Source 4
Sahvelo has read all four of these states at their own sources. Another state's rule may differ, and we would rather say that than generalize. The states here have all adopted the Revised Uniform Anatomical Gift Act, and the substantive rule does not vary between them. A death elsewhere is governed by that state's version.
Questions people ask about this
-
Can I change my mind after registering?
Yes — the donor can always amend or revoke, which is the point of the rule barring everyone else, and Arizona, California, Florida and New York each say so in their own statute. Each of them also sets out how: removing your name from the registry, a later document that revokes the gift, or destroying the document of gift. Do it in the registry rather than only telling someone, because the registry is what gets checked.Source 1Source 2Source 3Source 4 -
What if my family objects at the time?
In these four states they cannot override a registration. In practice a procurement organization confronted with a distraught family may still not proceed, which is a reason to have told them in advance rather than a reason to doubt the law.Source: A.R.S. §36-847 (Preclusive effect of anatomical gift, amendment or revocation) — Arizona State Legislature (opens in a new tab)•Source: California Health and Safety Code §7150.35 (Revised Uniform Anatomical Gift Act — bar on amendment or revocation by another) (opens in a new tab)•Source 3Source 4 -
My relative died and was not registered. Who decides?
A statutory priority order, beginning with a health care surrogate the person appointed and then the spouse and other relatives in sequence. Absent actual notice that the person objected, the person highest in that order may make the gift. The window is short, and the hospital's procurement co-ordinator will explain the specific order that applies.Source 3 -
Is this the same as donating a kidney while alive?
No. Living donation is an entirely separate process, arranged with a transplant center and involving its own evaluation and consent. Nothing on this page applies to it. -
What about donating my body to a medical school?
That is a distinct arrangement, usually made directly with the institution and registered with it in advance. It can conflict with organ donation, since a body accepted for anatomical study may not be available for organ recovery, so record which you intend to take priority. -
Does my advance directive cover this?
It can, and it should say the same thing as the registry. But a directive is a document someone has to find and read, and donation decisions are made in hours. Register as well, and use the directive to confirm rather than to carry the decision.
