Estate Administration Checklist: Every Document and Step You Need

You've been named executor, the funeral is behind you, and now you're staring at a mountain of paperwork with no clear idea what's urgent and what can wait. The average non-professional executor spends roughly 570 hours over 16 months settling an estate — and 87% describe the process as highly stressful.

The difference between executors who survive that marathon and those who collapse under it usually comes down to one thing: a checklist that separates the first-week emergencies from the month-six filings.

First 48 Hours

These tasks are time-sensitive. Everything else can wait.

• Obtain the death certificate. Order 10 to 20 certified copies from the vital statistics office or registrar. Banks, insurers, and government agencies each need their own original.
• Locate the original will. Courts rarely accept photocopies without a hearing. Check the deceased's home, safe deposit box, attorney's office, and email for digital scans.
• Secure physical property. Change locks on unoccupied homes. Store valuables. Arrange care for pets and dependents.
• Note any organ donation or funeral directives in the will or a separate advance directive, and act on them immediately.

Contacting financial institutions, appraising assets, and starting the probate application are usually postponable until you have located the will and obtained key documents. Focus first on securing property and arranging care for dependents.

First Week

• Obtain additional certified death certificates as needed from the local registrar or Department of Home Affairs. The court and each institution can tell you how many copies they require.
• Identify and care for dependents. If the deceased had minor children, elderly dependents, or pets, arrange immediate care.
• Begin a document binder. Physical or digital — every receipt, letter, and court filing goes in here from day one. This binder protects you if your decisions are ever questioned.

First Month

• Lodge the original will with the probate court or registry. In the US, file with the local court that handles probate (the court's name varies by state). In the UK, the HMCTS Probate Portal handles online applications. In Australia, file with the Supreme Court Probate Registry.
• Apply for Letters Testamentary (if there's a valid will) or Letters of Administration (if intestate). This document is your legal authority to act.
• Get an Employer Identification Number (EIN) from the IRS for the estate (US). In Canada, request a CRA trust account number if the estate needs one. In the UK, check with HMRC whether the estate needs to be registered for tax and issued a reference.
• Open a dedicated estate bank account. Every dollar in and out of the estate flows through this account — never commingle estate funds with personal money.
• Notify financial institutions — banks, brokerages, pension providers, insurance companies — with certified death certificates and your Letters Testamentary.

One to Three Months

• Inventory all assets. Real property, bank accounts, investment portfolios, vehicles, life insurance, retirement accounts, business interests, digital assets, and personal property of significant value.
• Get professional appraisals for real estate, business interests, art, jewelry, and collectibles. Court filings require documented fair market values.
• Identify known creditors. Review mail, email, credit reports, and financial statements to build a complete list.
• Notify the Social Security Administration (US), DWP (UK), or Centrelink (AU) to stop benefit payments and apply for any survivor benefits.

Three to Six Months

• Publish statutory notice to creditors in a court-approved newspaper where required. Notice requirements, claims periods, and the effect of a late claim vary by jurisdiction; do not assume a missed deadline extinguishes every creditor's claim.
• Send direct notice to all known creditors with the estate's case number and filing deadline.
• File the asset inventory and appraisal with the probate court where required (e.g., Form J243 in some jurisdictions).
• Review and accept or dispute creditor claims as they come in. Pay valid claims in the statutory priority order — never distribute to beneficiaries before creditor claims are resolved, or you risk personal liability.

Six to Twelve Months

• Check whether a final individual income tax return is required and file it by the applicable deadline — IRS Form 1040 (US), Self Assessment (UK), T1 return (Canada), or individual tax return through the ATO (Australia).
• File the estate's fiduciary income tax return — IRS Form 1041 (US) if the estate meets a filing requirement for income earned after death.
• Pay all outstanding taxes. In Canada, the "deemed disposition" rule means the estate owes capital gains tax on unrealized appreciation as if every asset were sold the day before death. In the UK, inheritance tax at 40% applies above the nil-rate band.
• Resolve any remaining creditor claims before the statutory bar date expires.

Twelve Months and Beyond

• Prepare a final financial accounting of every transaction — receipts, disbursements, distributions, and fees. Beneficiaries and the court review this.
• Obtain signed release and indemnity agreements from all beneficiaries before final distribution. This protects you from future claims.
• Distribute remaining assets according to the will (or intestacy rules).
• File for formal discharge from the court, releasing you from personal liability as executor.
• Keep estate records for at least six years (longer if there's any chance of a tax audit or beneficiary dispute).

The Documents Checklist

At minimum, you'll need these in your binder before probate can proceed:

Staying Organized Under Pressure

Estate administration hits hardest when grief fog makes even routine paperwork feel impossible. The research on bereaved decision-makers is clear: cortisol floods the brain, the prefrontal cortex slows down, and short-term memory suffers.

A structured checklist isn't a nice-to-have — it's the difference between catching a filing deadline and missing it.

Our How to Read and Execute a Will toolkit breaks this entire process into a step-by-step roadmap with fillable trackers, statutory deadline logs, and communication scripts — built specifically for executors working through grief.
