Estate Planning in Delaware: A Complete Guide for Residents

Most Delaware residents start thinking about estate planning after a scare — a health crisis, a death in the family, or the sudden realization that their children would be left without a named guardian. By that point, the stress makes everything harder.

Delaware's estate planning framework looks deceptively simple from the outside. Three counties, a handful of forms, a few signatures. But the state operates under its own statutory code rather than the Uniform Probate Code, and each county Register of Wills runs a separate filing system with different fees, deadlines, and procedures. Miss a detail — like the 10-day will lodging requirement under 12 Del. C. § 1301 — and your family inherits a legal headache along with everything else.

The Five Documents Every Delaware Estate Plan Needs

A basic Delaware estate plan consists of five core documents. Without all five, gaps in coverage leave your family scrambling during a crisis.

1. Last Will and Testament. Directs who receives your property and names an executor to manage your estate through probate. Delaware does not recognize handwritten (holographic) wills — your will must be signed in the presence of two competent adult witnesses to be valid.

2. Durable Power of Attorney. Authorizes a trusted person to handle your financial and legal affairs if you become incapacitated. Under 12 Del. C. Ch. 49A, the document must be signed before a notary and witnessed by one unrelated adult who is not a beneficiary. Your agent must also sign a statutory Agent's Certification before any financial institution will honor the document.

3. Advance Health-Care Directive. Names a health-care agent and documents your treatment preferences. Delaware's five-point witness exclusion rule bars relatives, beneficiaries, anyone with a financial claim against your estate, anyone financially responsible for your medical care, and employees of your residential care facility from serving as witnesses.

4. Transfer on Death Deed. Since December 2025, Delaware's Uniform Real Property Transfer on Death Act allows homeowners to designate a beneficiary who automatically inherits real estate outside of probate. The deed must be signed, notarized, witnessed by two people (at least one must not be a named beneficiary), and recorded with the county Recorder of Deeds before the owner's death.

5. Beneficiary Designations. Bank accounts, retirement funds, and life insurance policies pass directly to named beneficiaries — bypassing probate entirely. These designations override your will, so they must be reviewed whenever your circumstances change.

County-Specific Filing Differences You Need to Know

Delaware's three counties each run their own Register of Wills with different procedures:

New Castle County uses mandatory electronic filing through File & ServeXpress. Paper filings are not accepted. Opening fees range from $30 to over $1,905 depending on estate value, and the closing fee is 2.00% of the net personal estate (1.75% base plus a 0.25% technology surcharge).

Kent County operates entirely on paper. Documents must be submitted by mail or in person. Late filings trigger a $25 penalty for anything more than 30 days past deadline. The closing fee is 1.75% of the net personal estate.

Sussex County also uses paper filing, but adds a unique step: before scheduling an in-person closing appointment, the personal representative must complete a phone audit with the Chief Deputy Register. The closing fee is 1.25% — the lowest in the state.

Two Recent Law Changes That Reshape Delaware Estate Planning

Small Estate Threshold Increase (June 2026). House Bill 333 raised the small estate affidavit threshold from $30,000 to $50,000. If a decedent's solely owned personal property falls below this limit and includes no solely owned real estate, the estate can bypass formal probate entirely using a simplified affidavit process after a 30-day waiting period.

Transfer on Death Deed Act (December 2025). House Bill 147 adopted the Uniform Real Property Transfer on Death Act, giving Delaware homeowners a new tool to pass real estate directly to a beneficiary without going through probate. The owner retains complete control during their lifetime and can revoke the deed at any time.

What a Delaware Estate Plan Costs

Local Delaware estate planning attorneys typically charge $3,000 to $6,000 for a basic plan (will, power of attorney, and health-care directive). Trust-based plans routinely exceed $10,000. National document generators like LegalZoom charge $89 to $399 but often lag behind Delaware-specific legislative changes.

The Delaware Basic Estate Planning Kit provides county-compliant instructions, checklists, and step-by-step guidance for every essential document — updated for the 2025-2026 legislative changes — at a fraction of attorney fees.

Start With Your Asset Titles

The single most productive first step is auditing how your assets are currently titled. List every account, property, and vehicle. Note whether each is solely owned, jointly held, or has a named beneficiary. This audit reveals exactly which assets would go through probate if you died today — and which ones already bypass it.

That gap between "would go through probate" and "already bypasses it" is where your estate plan does its work.
