Common Mistakes in Delaware Intestate Probate Forms

Filing probate forms when someone dies without a will in Delaware is already stressful. You're grieving, you're sorting through paperwork, and you're trying to follow legal procedures you may have never dealt with before. One wrong box checked, one missing signature, or one incorrect heir listed and the whole process stalls. Delays cost time and money. Worse, mistakes can lead to disputes among family members or even legal liability for the person administering the estate. That's why understanding common mistakes when filing Delaware intestate succession probate forms before you start can save you weeks of frustration and hundreds of dollars in corrections.

What does filing Delaware intestate succession probate actually mean?

When a Delaware resident dies without a valid will, their estate goes through intestate succession a legal process where state law decides who inherits what. The Delaware intestate succession laws set a strict order of inheritance, starting with the surviving spouse and children, then branching outward to parents, siblings, and beyond.

The probate court oversees this process. Someone usually a surviving spouse or adult child petitions the Delaware Register of Wills (Surrogate's Court) to be appointed as the estate's administrator. That person then files a series of forms, inventories the estate, pays debts, and distributes assets according to the law.

It sounds straightforward on paper. In practice, the forms are detailed, the requirements are strict, and small errors create real problems.

Who needs to worry about getting these forms right?

If you've been named or are stepping up to administer a Delaware estate where no will exists, this applies directly to you. That includes:

Surviving spouses handling a partner's estate
Adult children petitioning to become administrator
Siblings or parents of a deceased person with no spouse or children
Anyone helping a family member navigate the probate process informally

Even if you plan to hire a probate attorney, understanding these mistakes helps you spot problems early and ask better questions.

Mistake #1: Filing in the wrong county

Delaware probate forms must be filed with the Register of Wills in the county where the deceased person lived at the time of death not where they owned property, not where you live, and not where they died if they were in a hospital or care facility in a different county.

Delaware has only three counties New Castle, Kent, and Sussex but each has its own Register of Wills office with slightly different local procedures. Filing in the wrong county means your petition gets rejected, and you start over.

What to do: Confirm the deceased's legal residence at the time of death. Use their last driver's license address, voter registration, or tax returns as evidence if there's any doubt.

Mistake #2: Not identifying all legal heirs

This is one of the most damaging errors. Under Delaware's intestate succession statute (Title 12, Chapter 1 of the Delaware Code), the order of inheritance is specific and sometimes surprising. People often assume only a spouse inherits, or only children inherit, when the law may split the estate differently.

For example, if the deceased had children from a previous relationship, those children have inheritance rights even if the surviving spouse didn't know them well. If the deceased had no spouse or children, the estate goes to parents, then siblings and half-siblings are treated the same as full siblings under Delaware law.

Failing to list all known heirs on the petition forms can lead to:

Rejected filings
Legal challenges from omitted heirs later
Personal liability for the administrator

What to do: Research the deceased's family history thoroughly before filing. Check for prior marriages, children from other relationships, and any estranged family members who still have legal standing. Our guide on who inherits under Delaware intestate succession laws breaks down the exact order.

Mistake #3: Using the wrong forms or outdated versions

Delaware's Register of Wills offices periodically update their forms. Using an outdated version pulled from an old website, a friend's file, or a DIY legal template site is a common reason for rejected filings.

Each county may also have specific supplemental forms. The forms for a surviving spouse petitioning as administrator differ slightly from those filed by a non-spouse heir.

What to do: Download forms directly from the specific county's Register of Wills website or pick them up in person. Confirm you have the current version before filling anything out. If you need help understanding which forms to use, see our breakdown of Delaware Surrogate Court intestate estate administration forms.

Mistake #4: Incomplete or inaccurate estate inventory

Once appointed as administrator, you're required to file an inventory of the estate's assets with the Register of Wills. This includes real estate, bank accounts, vehicles, personal property, investments, and business interests.

Common inventory errors include:

Forgetting digital assets like cryptocurrency or online accounts with monetary value
Underestimating property values without getting appraisals
Leaving out jointly held assets that may need legal review
Missing debts owed to the deceased
Not listing life insurance policies (which may or may not pass outside probate depending on beneficiaries)

An incomplete inventory doesn't just slow things down it can make you personally liable if beneficiaries later discover hidden or undervalued assets.

What to do: Go through the deceased's mail, email, tax returns (at least three years), and financial statements systematically. Get professional appraisals for real estate and valuable personal property.

Mistake #5: Missing filing deadlines

Delaware doesn't give you unlimited time to file probate paperwork. The petition to open an intestate estate should generally be filed promptly, and once you're appointed administrator, you have specific deadlines for filing the inventory, accounting, and distribution documents.

Missed deadlines can result in:

Court sanctions
Removal as administrator
Complaints from heirs or creditors

What to do: Create a timeline as soon as you file the initial petition. Write down every court-imposed deadline and set reminders at least two weeks in advance. The court clerk can confirm specific deadlines for your case.

Mistake #6: Paying debts and distributing assets in the wrong order

Delaware law sets a priority order for paying estate debts. Administrative expenses and funeral costs come first, followed by certain taxes, then secured debts, then unsecured debts. If the estate doesn't have enough money to cover everything, you must pay in order and stop when funds run out.

A common mistake is distributing assets to heirs before all debts and taxes are paid. If you do this and a creditor later comes forward, you may have to pay the creditor out of your own pocket or face legal action.

What to do: Wait until the claims period expires and all valid debts are resolved before distributing anything to heirs. Publish the required creditor notice in a Delaware newspaper as required by law.

Mistake #7: Forgetting to file the final accounting

The job isn't done when you hand out the assets. Delaware requires administrators to file a final accounting with the Register of Wills showing every dollar that came in, every dollar that went out, and how the remainder was distributed. Failing to file this document can keep the estate technically open indefinitely and expose you to future claims.

What to do: Keep detailed records of every financial transaction from day one. Save receipts, bank statements, canceled checks, and correspondence. When it's time to file the accounting, the numbers should match your documentation exactly.

Mistake #8: Trying to handle everything alone without knowing the risks

Many people assume probate forms are just paperwork. They're not. As an administrator, you're acting in a legal fiduciary role. You can be held personally responsible for mistakes even honest ones. If you distribute money to the wrong person, miss a tax filing, or overlook a creditor, the consequences fall on you.

This doesn't mean you need a lawyer for every step. But you should know where your knowledge ends and where professional help becomes necessary.

What to do: Consider consulting a Delaware probate attorney for at least the initial petition and the final accounting. Many offer flat-fee consultations specifically for intestate estates.
