Estate Planning Checklist for Married Couples in 2026

What Every Married Couple Needs on Their 2026 Estate Plan

A first estate plan for a married couple comes down to five documents: a last will and testament, a revocable living trust (when your situation calls for one), a healthcare power of attorney, a financial power of attorney, and up-to-date beneficiary forms. Get those in place and you've covered the decisions that matter most.

This is something you build together, not a solo task one of you handles alone. When both partners understand where the accounts are, who inherits what, and who steps in during a medical emergency, you replace guesswork with clarity. That shared understanding is the point.

Here's the 2026 reality: OBBBA (passed in 2025) permanently set the federal estate and gift tax exemption at $15 million per person, or $30 million for a married couple. For the vast majority of couples, federal estate tax is no longer the concern. Your plan is about control and coordination, not tax avoidance.

And it matters at every stage. A couple in their 30s with a house, two 401(k)s, and a young child has real estate planning questions today. Guardianship, account access, and titling don't wait until you're wealthy or retired.

How the 2026 Exemption and Marital Deduction Change Your Planning

Starting in 2026, each spouse has a $15 million federal lifetime gift and estate tax exemption. Combined, that's $30 million a married couple can pass to heirs without owing federal estate tax. The IRS administers these rules, and OBBBA made the higher figure permanent, removing the scheduled 2026 rollback that had been looming for years.

The unlimited marital deduction is a separate tool. It lets one spouse transfer any amount of assets to the other, during life or at death, without triggering federal gift or estate tax. That sounds like a complete solution, but there's a catch: the deduction defers tax, it doesn't erase it. Assets that pass to the surviving spouse tax-free become part of that spouse's estate, and they're measured against that spouse's exemption when they die.

State taxes are the piece couples most often miss. A dozen or so states, plus the District of Columbia, impose their own estate or inheritance tax, and several use thresholds far below the federal $15 million figure. Oregon and Massachusetts, for example, start taxing estates in the low seven figures. If you live in or own property in one of those states, your plan needs to account for it even when no federal tax applies.

As Michael C. Cotugno, Esq., Managing Partner at Neptune Legal, puts it: "For conscious partners, wealth is not merely a collection of assets; it's a powerful tool with the potential for profound purpose." Planning together lets you decide what that purpose is.

The Married Couple Estate Planning Checklist Step by Step

Work through these steps in order. The sequence matters, because a few of them override the others.

1. Inventory your assets and debts together. List real estate, bank and brokerage accounts, retirement accounts, life insurance, business interests, vehicles, and meaningful personal property. Note how each is titled. This is the balance sheet conversation, and it's the foundation for everything else.
2. Confirm titling on every asset. How something is owned determines what happens to it at death, sometimes regardless of what your will says.
3. Update every beneficiary form. Do this before you draft anything. Retirement accounts and life insurance pass by beneficiary designation, not by will, so an outdated form quietly overrides your plan.
4. Draft wills for each spouse. Each will names an executor, directs how property is distributed, and (for parents) names a guardian.
5. Decide whether you need a revocable living trust. More on that below.
6. Complete powers of attorney and healthcare directives. These let each spouse make financial and medical decisions for the other during incapacity.

For parents, naming a guardian for minor children is the single most important step. Without it, a court decides who raises your kids, and that decision may not match what either of you would have chosen.

One rule catches couples off guard: federal law generally requires your spouse to be the beneficiary of your 401(k) unless they sign a written waiver. So even if you intend to name someone else, you typically need your spouse's signed consent.

Wills vs. Revocable Living Trusts for Couples

A will alone works for many households, especially those under roughly $1 million in non-retirement assets living in states with straightforward probate. A revocable living trust (a legal arrangement where a trustee holds assets on your behalf) avoids probate, keeps your affairs private, and is often worth the added cost if you own real estate in more than one state or live somewhere with slow, expensive probate such as California or Florida.

Even if you set up a trust, you still need a will, usually a "pour-over will" that catches anything not titled into the trust. Most couples end up with both documents. Which combination fits you is a decision you make together, with an attorney who can weigh your state's rules and your specific assets.

How Asset Titling and Beneficiary Designations Work

The way an asset is titled controls what happens to it when you die and whether it goes through probate. This is where good intentions and paperwork drift apart.

Certain accounts pass entirely by beneficiary form, no matter what your will says. That includes IRAs and Roth IRAs (contact your brokerage), 401(k) and 403(b) plans (contact your employer's HR or the plan administrator), life insurance (the insurer), and payable-on-death or transfer-on-death bank and brokerage accounts (your bank or brokerage). Reviewing beneficiary designations is a step government consumer resources and estate professionals consistently put near the top of the list.

The most common planning mistake isn't a missing document. It's coordination failure. Your will says one thing, an old 401(k) form says another, and a jointly titled house does a third. When those three don't line up, the beneficiary form and the titling usually win, and your carefully drafted will can't fix it. That's why the checklist puts titling and beneficiaries before drafting.

How Neptune Manages the Estate Planning Process for Couples

Neptune handles the full process from start to finish. We pair you with experienced estate attorneys and financial professionals (attorneys with 20+ years of experience, plus CFPs and CPAs), and we coordinate the moving pieces so titling, beneficiaries, and documents actually line up.

The estate planning bundle is a flat $3,000, with guided education along the way so you understand each decision rather than just signing where the arrow points. You move through it as a couple, at a pace that lets both partners weigh in.

"Understanding a partner's relationship with money, their historical experiences of abundance or scarcity, their anxieties tied to financial stability, or their personal definitions of success, allows for a deeper, more empathetic understanding of them as a whole individual," says Michael C. Cotugno, Esq., Managing Partner at Neptune Legal. Estate planning tends to surface exactly those conversations, which is part of why doing it together strengthens the partnership.

When to Review and Update Your Estate Plan

An estate plan is not one-and-done. A good rule of thumb is to review it together at least once every three to five years, and any time a major life event changes your picture.

Trigger events worth a review include:

• Marriage or remarriage
• A new child or grandchild
• Moving to a different state (titling and probate rules vary)
• A new job, a rollover, or a new retirement account
• Buying or selling real estate
• The death of a spouse, beneficiary, executor, or named guardian

Reviewing as a team keeps both partners' wishes current and documented, and it reduces the confusion and conflict families face later. State bar associations, such as the American Bar Association, publish public guidance that reinforces the same point: plans need to reflect where you are today, not where you were when you first signed.
