Estate Planning Checklist: 8 Documents Every Family Needs (2026)

A complete estate plan has eight parts: a will, a financial power of attorney, a healthcare power of attorney, a living will (advance directive), up-to-date beneficiary designations, a list of assets and accounts, guardianship instructions if you have minor children, and — for larger or more complex estates — a living trust. Together these decide who manages your affairs if you can't, who inherits what, and how much of the process your family has to take to court.

The eight essentials

Last will and testament — names who inherits your property and who serves as executor.
Revocable living trust — lets assets pass without probate; most valuable if you own real estate or want privacy.
Durable financial power of attorney — lets someone manage money and bills if you're incapacitated.
Healthcare power of attorney — names who makes medical decisions for you.
Living will / advance directive — states your wishes for end-of-life care.
Beneficiary designations — on retirement accounts and life insurance; these override your will, so keep them current.
Guardianship designation — names who raises your minor children.
Asset inventory — a simple list of accounts, property, and where documents are kept.

Will versus trust

A will alone still goes through probate — the public, sometimes slow court process for settling an estate. A living trust holds your assets so they pass directly to beneficiaries without probate, which saves time, keeps details private, and is especially useful if you own property in more than one state. Many families use both: a trust for major assets and a "pour-over" will as a backstop.

Keep it current

An estate plan is not one-and-done. Review it after any marriage, divorce, birth, death, big purchase, or move to a new state. Outdated beneficiary forms are one of the most common — and most avoidable — estate planning mistakes.

Where to start

An estate planning attorney can assemble all eight pieces correctly for a flat fee, and reviewing an existing plan is usually inexpensive. If you're settling a loved one's estate now and discovering these documents are missing or outdated, that's the strongest reason to get your own plan in order.
