Can Family Override a Living Will in Delaware?

The short answer: not legally, but it happens in practice when documents are poorly written, unavailable at the point of care, or when family members pressure medical staff into ignoring them.

Delaware law gives your advance health-care directive (AHCD) strong legal protection. Under 16 Del. C. § 2505, a properly executed directive takes precedence over family opinions, the default surrogate hierarchy, and even the preferences of your named healthcare agent — your written instructions override everyone if they're specific enough.

But "specific enough" is where problems start.

How Family Members Successfully Override Directives

It's not that Delaware law allows overrides. It's that vague documents create openings:

Ambiguous language. If your living will says "no extraordinary measures" without defining what that means, a family member can argue to the medical team that dialysis or a feeding tube isn't "extraordinary." Physicians stuck between a vague document and a vocal family member at the bedside often defer to the family.

Missing documents. If your directive isn't in the hospital's electronic health record and your family member tells the ER doctors your wishes are different from what you wrote, the medical team has no way to verify. They'll follow the family's verbal instructions rather than treat an invisible document as authoritative.

The default surrogate hierarchy. Without a named agent, Delaware's priority list kicks in: spouse, adult child, parent, sibling. If multiple people share the same priority level and disagree, the facility faces a deadlock. Some hospitals will petition the Court of Chancery for a guardian appointment to resolve the dispute — a process that costs $135 in filing fees plus $750+ for a court-appointed attorney ad litem, and takes weeks.

How to Prevent Overrides

Name a single healthcare agent. One person with sole decision-making authority eliminates majority-rules disputes among siblings. Your agent's decisions override all other family members, period.

Write specific instructions. Instead of "no heroic measures," specify: "I refuse mechanical ventilation if I have been diagnosed with a terminal condition with a life expectancy of six months or less." Give your agent and physicians no room for interpretation.

Address the pregnancy provision. Under Delaware law, life-sustaining treatment cannot be withdrawn from a pregnant patient whose fetus could survive to live birth — unless you explicitly state otherwise in your directive. If this default doesn't match your wishes, document your preference clearly in writing.

Get it into the system. Give copies to your physician for scanning into the EHR. Give copies to your named agent and alternate. Keep a copy accessible at home — not in a locked safe deposit box.

Discuss your wishes directly. A family that has heard you explain your reasoning in person is far less likely to fight your documented wishes when the moment arrives.

The Court of Chancery as Last Resort

If a family member believes your directive was signed under duress, that you lacked capacity when you signed, or that your agent is acting against your documented wishes, they can petition Delaware's Court of Chancery. The court can appoint a guardian to override both your agent and your directive — but only after a formal hearing with evidence.

This is rare and expensive. The petitioner pays filing fees, service costs, and attorney fees. The court treats guardianship as a "restrictive remedy of last resort" and requires a physician's affidavit certifying disability within three months of the filing.

For most families, the real protection is prevention: clear documents, distributed copies, and a chosen agent who will enforce your wishes under pressure.
