Estate Planning Basics
A plain-English introduction to wills, trusts, powers of attorney, and beneficiary designations - the core documents every adult should have.
Why Every Adult Needs an Estate Plan, in Plain Numbers
Roughly 40,000 federal estate tax returns (Form 706) are filed in the United States each year, according to IRS Statistics of Income, but that number captures only estates above the federal exemption threshold (a permanent $15 million per individual as of 2026, per the One Big Beautiful Bill Act). The real volume of estate activity runs through state probate courts, where the American College of Trust and Estate Counsel estimates over 1 million probate cases open annually. Without a will or trust, state intestacy statutes decide who inherits, who raises minor children, and who administers financial affairs, and the distribution rarely aligns with what the deceased would have chosen. Domestic partners in non-marriage states often receive nothing; blended-family stepchildren frequently inherit nothing. Probate typically takes 6 to 18 months and costs 3–7% of the gross estate in legal and court fees.
This guide covers the four core documents every adult needs, a will, a revocable living trust (for probate avoidance), durable financial and healthcare powers of attorney, and beneficiary designations on retirement accounts and life insurance, and explains why those designations override your will. It walks through when a simple will is sufficient, when a trust adds value, and how state-specific rules around community property, homestead exemptions, and intestate share change the calculus. Pair this guide with our per-state pages for specific exemption thresholds and probate thresholds in your jurisdiction.

Why Estate Planning Matters
Estate planning is the process of deciding how your assets transfer at death (or incapacity) - and documenting those decisions legally. Without a plan, state law decides: who inherits, who raises your children, and who controls your finances.
According to IRS Statistics of Income, about 40,000 estate tax returns are filed each year, but millions of families go through probate without proper planning, often losing months to court processes that could have been avoided.
The Core Documents
1. Last Will and Testament
A will specifies who inherits your property, names an executor (personal representative) to manage the process, and, critically for parents, designates a guardian for minor children. It must go through probate before assets transfer.
- Must be signed and witnessed (requirements vary by state)
- Does NOT control assets with named beneficiaries (retirement accounts, life insurance, POD accounts)
- Becomes a public record when filed in probate court
2. Revocable Living Trust
A trust holds assets during your lifetime and distributes them at death outside of probate, privately, efficiently, and often cheaper. You are typically the initial trustee and retain full control. At death, a successor trustee takes over.
- Avoids probate for all assets properly titled in the trust
- Not a tax-saving tool by itself, a revocable trust is a "grantor trust" taxed as your own income
- Can include sub-trusts for children, spouses, or special needs beneficiaries
- Requires "funding" - assets must be re-titled into the trust name to work
3. Durable Power of Attorney (Financial)
Authorizes a trusted person (your "agent") to manage finances if you become incapacitated, pay bills, file taxes, manage investments. "Durable" means it survives incapacity. Without one, families must petition a court for conservatorship, which is expensive and slow.
4. Healthcare Directive / Living Will
Two documents in one: (a) a healthcare proxy / medical POA designates who makes medical decisions if you cannot, and (b) an advance directive / living will states your wishes about life-sustaining treatment.
5. Beneficiary Designations
These override your will. Retirement accounts (401k, IRA), life insurance, and bank/brokerage TOD/POD accounts all transfer directly by designation, regardless of what your will says. Review them after every life event.
Estate plan cost comparison
| Approach | Typical cost | Risk of court intervention |
|---|---|---|
| DIY online templates | $50-$200 | High |
| Attorney-drafted basic | $1,500-$3,000 | Low |
| Attorney-drafted comprehensive | $3,000-$8,000 | Very low |
| No plan (guardianship petition) | $5,000-$30,000 | Court-determined |
A $2,000 estate plan is one of the highest-ROI financial decisions most adults will make.
Estate Tax Considerations
Federal estate tax applies to estates above a permanent $15M per person as of 2026 (One Big Beautiful Bill Act). Currently, 13 states plus DC also impose estate tax at lower thresholds, some as low as $1M, while 33 states levy neither an estate nor an inheritance tax at all. See our state comparison table for details.

Frequently Asked Questions
Do I need a will if I have a trust?
Yes. A "pour-over will" ensures any assets not titled in your trust at death flow into the trust. Without it, those assets go through probate under state intestacy law.
What happens if I die without a will?
You die "intestate." State law determines who inherits, typically a spouse, then children, then other relatives. Your wishes are irrelevant. Domestic partners may receive nothing.
How often should I update my estate plan?
Review after every major life event: marriage, divorce, birth, death of a beneficiary, significant asset change, or move to a new state. At minimum, every 3–5 years.
