At death, assets move to heirs through one of three channels: by contract, through beneficiary designations on retirement accounts and life insurance; by title, when jointly owned property passes automatically to the surviving owner; or by court process, when a will is administered through probate. A revocable trust adds a fourth channel that bypasses probate entirely. The will controls only what the other channels do not capture, which is why a technically valid estate plan can still send assets to the wrong people.

This primer explains the machinery: which assets pass which way, what probate actually involves, why beneficiary designations override wills, what trusts change, how the step-up in basis works, and what the administration timeline looks like for the family left to manage it.

What actually moves your assets when you die?

Most people assume the will is the master document. In practice, the will is the residual document. Each asset you own follows its own transfer rule, and the will only governs assets that have no other rule attached.

The four channels, in the order they typically operate:

  • Beneficiary designations (transfer by contract). IRAs, 401(k)s, life insurance, annuities, and accounts with transfer-on-death (TOD) or payable-on-death (POD) registrations pass directly to the named beneficiary. No court is involved.
  • Titling (transfer by operation of law). Property held in joint tenancy with right of survivorship, or as tenancy by the entirety between spouses, passes automatically to the surviving owner the moment the first owner dies.
  • Trusts (transfer by trust terms). Assets titled in the name of a trust are distributed by the trustee according to the trust document, outside of probate.
  • The will, through probate (transfer by court process). Everything else, meaning assets titled in your individual name with no beneficiary and no surviving co-owner, passes under your will after a court-supervised process. If there is no will, state intestacy law decides who inherits.

For many wealthy families, the majority of assets by dollar value pass through the first three channels. The will catches the remainder, which is why estate attorneys often pair a will with a revocable trust and then work to make sure the will has as little as possible to do.

What is probate and why do people avoid it?

Probate is the state court process that validates a will, appoints an executor (called a personal representative in Wisconsin and many other states), inventories the assets the will governs, pays debts and taxes, and distributes what remains. It exists to protect creditors and heirs, and in routine cases it works.

Families plan around it for three practical reasons. First, it is public: the will, the inventory in many states, and the identities of beneficiaries become court records. Second, it takes time; even uncontested estates commonly remain open for months to a year or more, and contested estates far longer. Third, it adds cost in the form of court fees, attorney fees, and in some states statutory executor commissions.

Probate is also state by state. A family with a Wisconsin home, a Florida condominium, and Arizona land may face three separate probate proceedings, called ancillary probates, unless the out-of-state real estate is held in a trust or entity. This multiplication of proceedings is one of the most common reasons families with property in several states adopt revocable trusts.

How property titling determines who inherits

The way an asset is titled is itself an estate planning decision, whether or not it was made deliberately.

Joint tenancy with right of survivorship (JTWROS) passes the entire asset to the surviving owner automatically. This is simple between spouses but can misfire elsewhere. A parent who adds one child to a bank account "for convenience" may have unintentionally disinherited the other children with respect to that account, because the joint titling overrides the will.

Tenancy in common is different: each owner's share passes under that owner's will, through probate, rather than to the co-owner. Tenancy by the entirety, available to married couples in some states, works like joint tenancy with added creditor protection. Community property, the regime in nine states including Wisconsin (which uses the marital property system, its version of community property), treats most assets acquired during marriage as owned half by each spouse, with a meaningful tax advantage at death discussed below.

TOD and POD registrations convert ordinary brokerage and bank accounts into non-probate assets by naming a death beneficiary. Many states, including Wisconsin, also permit transfer-on-death deeds for real estate.

Why beneficiary designations override your will

A beneficiary designation is a contract between you and the financial institution. The institution is obligated to pay the named beneficiary on proof of death, regardless of what your will says, and courts routinely enforce designations over contrary will provisions.

This is where well-drafted estate plans fail most often in practice. A hypothetical illustrates the stakes: an executive signs a new will and trust leaving everything equally to her three children, but her $4 million 401(k) still names her sibling, listed as beneficiary decades earlier before the children were born. At her death the $4 million goes to the sibling. The will is irrelevant to that account, and the children's recourse is limited to hoping the sibling voluntarily disclaims or gifts it back, with gift tax consequences of its own.

The discipline that prevents this is unglamorous: a periodic audit of every beneficiary designation against the current estate plan, after every marriage, divorce, birth, death, and account rollover. Rollovers are a quiet culprit, because a new IRA may default to "estate" or to no beneficiary at all, which can force a retirement account through probate and compress its income tax deferral.

What does a revocable trust actually change?

A revocable living trust is a container you create and control during life. You typically serve as your own trustee, retain full access, and can amend or revoke it at any time. For income tax purposes it is ignored while you are alive; it files no separate return and saves no income tax.

What it changes is mechanics. Assets titled in the trust avoid probate in every state where they sit, remain private, and are immediately manageable by your successor trustee if you become incapacitated, without a guardianship proceeding. At death, the trust becomes irrevocable and the successor trustee distributes or continues to hold assets per its terms, which can include ongoing trusts for a surviving spouse, children, or grandchildren.

A trust only governs what it owns. An unfunded trust, meaning one signed but never retitled into, accomplishes little; the assets still pass through probate, where a "pour-over" will catches them and moves them into the trust after the court process the trust was meant to avoid. Funding, meaning retitling accounts, deeds, and entity interests into the trust, is the step most often left incomplete.

Irrevocable trusts, such as SLATs, IDGTs, GRATs, and dynasty trusts, are a different category. They move assets out of your taxable estate during life and are covered in depth in our trust strategies article linked below.

What is the step-up in basis, and why does it matter so much?

Under Section 1014 of the Internal Revenue Code, most appreciated assets included in a decedent's estate receive a new income tax basis equal to fair market value at death. The embedded capital gain accrued during the decedent's life is never taxed to anyone.

A hypothetical example: a retired founder holds stock bought decades ago for $500,000, now worth $10.5 million. If she sells during life, roughly $10 million of long-term gain is taxable, which at a combined federal rate of 23.8 percent (20 percent capital gains plus the 3.8 percent net investment income tax) is approximately $2.38 million of federal tax before state tax. If instead her heirs inherit the stock, their basis resets to $10.5 million, and they can sell the next day with essentially no capital gains tax. The same step-up applies to real estate, business interests, and taxable brokerage assets; it does not apply to retirement accounts, annuities, or other "income in respect of a decedent," which remain fully taxable to heirs as withdrawn.

Two refinements matter for couples. In most states, jointly held property gets a step-up on only the deceased spouse's half. In community property states, including Wisconsin under its marital property law, both halves of marital property can receive a full step-up at the first death, a significant advantage that depends on how assets are classified and titled. And assets given away during life keep your old basis in the recipient's hands, which is why low-basis assets are often better held until death while cash or high-basis assets are gifted.

What does estate administration actually look like?

A simplified timeline for a typical seven-or-eight-figure estate, assuming no disputes:

Period What happens
Weeks 1 to 4 Death certificates ordered; attorney engaged; will and trust located; assets secured; immediate family cash flow addressed
Months 1 to 3 Probate opened if needed and executor appointed; trustee takes control of trust assets; beneficiary claims filed for life insurance and retirement accounts; date-of-death valuations and appraisals begin
Months 3 to 9 Creditor claim period runs; final income tax return prepared; estate or trust obtains its own tax ID and begins filing fiduciary income tax returns; valuations of businesses and real estate completed
Month 9 Federal estate tax return (Form 706) due, with a 6 month extension available; a return may be filed even for non-taxable estates to elect portability of the deceased spouse's unused exemption
Months 9 to 18+ Debts and taxes paid; assets distributed or moved into ongoing trusts; probate closed; ongoing trusts continue under the trustee

The federal backdrop in 2026: the estate, gift, and GST exemption is $15 million per person, or $30 million for a married couple, permanent and inflation-indexed under the One Big Beautiful Bill Act, with a 40 percent tax above it. Annual gifts of up to $19,000 per recipient (IRS Revenue Procedure 2025-32) pass free of gift tax without touching the exemption. Wisconsin imposes no state estate or inheritance tax, but several other states do, which matters for families with property or residency elsewhere.

Key numbers

Item 2026 figure
Federal estate, gift, and GST exemption $15,000,000 per person; $30,000,000 per married couple
Federal estate tax rate above exemption 40%
Annual gift tax exclusion $19,000 per recipient (IRS, Rev. Proc. 2025-32)
Form 706 due date 9 months after death; 6 month extension available
Step-up in basis Basis resets to fair market value at death for most included assets (IRC Section 1014)
Wisconsin estate or inheritance tax None

Frequently asked questions

Does a will avoid probate?No. A will is the instruction manual for probate, not a way around it. Avoiding probate requires beneficiary designations, survivorship titling, or a funded revocable trust.

What happens if someone dies without a will?State intestacy law distributes probate assets to relatives in a fixed order, typically spouse and children first. Non-probate assets still pass by designation and titling, with or without a will.

Do beneficiary designations really override a will?Yes. The designation is a contract honored by the financial institution regardless of the will's terms, which is why designations should be audited whenever the estate plan changes.

Do heirs pay income tax on what they inherit?Generally not on the inheritance itself, and appreciated assets usually arrive with a stepped-up basis. The major exception is inherited retirement accounts and other income in respect of a decedent, which are taxed as ordinary income when withdrawn.

How long does it take to receive an inheritance?Life insurance and beneficiary-designated accounts often pay within weeks. Probate and trust distributions commonly take 9 to 18 months for estates of meaningful size, and longer when businesses, real estate, or a Form 706 are involved.

Is a revocable trust only for the very wealthy?No. Its core benefits are privacy, incapacity management, and probate avoidance, which apply at many wealth levels and in any state where you own real estate.
