Delaware Advance Directive: How It Works and Why the Witness Rules Matter

A Delaware advance directive lets a competent adult designate a healthcare agent and specify what medical treatment they want — or don't want — if they can no longer communicate their wishes. It governs decisions about life-sustaining treatment, mechanical ventilation, artificial nutrition, and anatomical gifts. Getting this document right before a health crisis avoids the chaos of emergency guardianship proceedings in the Court of Chancery. Getting the witness requirements wrong invalidates it entirely — and that happens far more often than people expect.

What a Delaware Advance Directive Covers

A Delaware advance directive serves two functions:

1. Healthcare agent designation: You name one or more individuals to make medical decisions on your behalf if you become incapacitated. This person — sometimes called a healthcare proxy — has authority to communicate with physicians, consent to or refuse treatment, and access your medical records.

2. Specific treatment instructions: You can specify your wishes regarding CPR, mechanical ventilation, dialysis, artificial nutrition and hydration, pain management, and whether you want to donate organs or tissues.

The directive can be as specific or as general as you choose. Many people name a trusted agent and give that agent broad discretion rather than attempting to anticipate every possible medical scenario.

The Witness Requirements — and Why They Invalidate Documents

Delaware imposes strict witness rules that routinely catch people off guard.

Standard requirement: The advance directive must be signed by two witnesses who:

• Are not related to the principal (by blood, marriage, or adoption)
• Are not entitled to any portion of the principal's estate
• Have no financial responsibility for the principal's medical care

Nursing home and long-term care requirement: If the principal resides in a long-term care facility, hospital, or nursing home at the time of signing, one of the two witnesses must be a patient advocate or an ombudsman designated by the Delaware Department of Health and Social Services.

This requirement exists to protect vulnerable individuals from signing documents under pressure from facility staff or family members who stand to inherit. But it creates a practical problem: many people sign advance directives after moving into a care facility, without realizing this special witness requirement applies. Directives lacking the ombudsman signature are routinely rejected by Delaware hospitals and care facilities when the document is actually needed.

If a directive is deemed invalid at the moment of crisis, the family may need to seek emergency guardianship through the Court of Chancery — a process that can take days, costs significantly more than the original document preparation, and plays out while the person is receiving care that may not align with their wishes.

What to do if the document may be invalid: Contact the facility's patient advocate or the Delaware Long-Term Care Ombudsman Program to assess whether the document needs to be re-executed. Act while the person still has capacity.

The DMOST Form: A Separate, More Urgent Document

Many people confuse the advance directive with the DMOST form. They serve different purposes and operate in different contexts.

The DMOST (Delaware Medical Orders for Scope of Treatment) is not an advance directive — it is an actual medical order. It is used for individuals with serious illness, frailty, or advanced age who want their care preferences to be immediately actionable across all care settings, including emergency situations.

Key differences:

• An advance directive is a legal document that guides future decision-making. The DMOST is a current medical order.
• A DMOST must be signed by a physician or advanced practice nurse — it is a clinical document, not a planning document.
• Emergency responders (EMTs, paramedics) are legally bound to follow a DMOST. An advance directive, by contrast, must be communicated to and interpreted by medical staff.
• The DMOST is a distinctive bright pink form designed to be recognizable in an emergency.

For someone with a serious illness or declining health, both documents are important. The advance directive covers the broader span of medical decision-making. The DMOST handles the immediate moments — CPR, mechanical ventilation, transport to the hospital — when there is no time for nuanced interpretation.

If you are helping manage a loved one's affairs who has a serious diagnosis, locate the DMOST form immediately. It governs the moments leading directly to death.

What Happens to the Advance Directive at Death

The advance directive ceases to have legal authority the moment the person dies. It governs only while the person is alive but incapacitated.

After death, decision-making authority shifts entirely. The executor named in the will (or an administrator in an intestate estate) takes over the administration of the estate. The healthcare agent named in the advance directive has no authority over funeral arrangements or estate matters unless they are also named in the will.

Delaware statute establishes a separate hierarchy for authorizing funeral disposition, starting with the surviving spouse, then a majority of adult children, then parents, then siblings. Neither the advance directive nor the healthcare agent designation controls this process.

How the Advance Directive Connects to Estate Settlement

When someone dies following a period of incapacity, the executor often inherits a situation that was shaped by decisions made under the advance directive — care facility choices, treatments pursued or declined, assets spent on long-term care. Understanding what the directive authorized helps the executor reconstruct the financial picture and anticipate potential Medicaid estate recovery claims from the state.

Delaware's Medicaid program can assert a claim against the estate for long-term care costs paid on the decedent's behalf. This claim operates within the same probate process as other creditor claims — it must be filed within the eight-month creditor window, and it is subject to the same statutory priority rules as other debts.

The Delaware Estate Settlement Guide covers the full estate settlement process, including how to handle Medicaid claims, the order for paying estate debts, and what to do with assets that were held in various legal structures at the time of death.
