The right time to start estate planning is when you turn 18, and if you’ve passed that milestone without any documents in place, the right time is now. Legal adulthood strips your parents of the automatic authority to make medical or financial decisions for you, so a few basic documents belong in place long before the wealth or the gray hair arrives. After that first set, every major life change becomes its own prompt to update.
Why 18 Is the Starting Line
The day you turn 18, a hospital can legally refuse to discuss your condition with your parents, and your bank can refuse to let anyone else touch your accounts. If something goes wrong and you haven’t named someone to act for you, your family’s only route is a court guardianship petition. That process costs thousands of dollars, takes months, and puts private family details into public records.
At a minimum, every adult should have three documents regardless of net worth:
- A healthcare power of attorney, letting someone make medical decisions if you can’t.
- A durable financial power of attorney, letting someone pay bills and manage accounts.
- A basic will.
These are inexpensive to prepare and easy to update. Having them in your 20s is not overkill; it’s the floor.
Life Events That Should Send You Back to the Documents
Marriage
Marriage reshapes your legal and financial identity. Any will, trust, or beneficiary designation signed before the wedding likely names someone other than your spouse. Review how jointly held assets are titled, and confirm that retirement accounts, life insurance policies, and bank accounts name the right people. Beneficiary designations override whatever your will says, so a 401(k) still listing an ex gets paid to that ex no matter what your will directs.
A New Child
The birth or adoption of a child creates one obligation no other event matches: naming a legal guardian. If both parents die without a will designating a guardian, a court picks who raises your child without your input. Parents should also consider a trust so any inheritance is managed by a trustee until the child reaches an age the parents are comfortable with. Most parents don’t want an 18-year-old receiving an unrestricted lump sum.
Divorce
Divorce calls for a complete overhaul. Update your will, remove your ex from powers of attorney and healthcare directives, and change beneficiary designations on every account. Some states automatically revoke certain bequests to an ex-spouse on divorce, but many don’t reach beneficiary designations on retirement accounts or life insurance. The divorce decree alone doesn’t clean this up.
Death of a Spouse
The surviving spouse needs to review every document, because the deceased spouse was likely named in key roles. There’s also a tax decision with a hard deadline. To claim a deceased spouse’s unused portion of the federal estate tax exemption (called portability), the surviving spouse must file IRS Form 706, generally within nine months of death, even if the estate owes no tax.1Internal Revenue Service. Instructions for Form 706 Skipping the filing permanently forfeits that extra exemption.
Moving to a New State
This one gets overlooked. Documents valid in one state may not operate the same way in another, and state-level estate tax thresholds vary dramatically. Roughly a dozen states impose their own estate or inheritance taxes, some with thresholds of $1 million or less. If you own property in one of them, the generous federal exemption doesn’t tell the whole story.
Financial Changes That Should Prompt an Update
Growing Net Worth
Buying your first home, landing a higher-paying job, receiving an inheritance, or building a serious investment portfolio all change what’s at stake. Real estate needs to be addressed in your plan, either titled into a trust or handled by your will. A big jump in net worth can also push your estate closer to tax thresholds, which brings tools like irrevocable trusts and gifting strategies into play.
Beneficiary Designations
Beneficiary designations on financial accounts override your will. If your will leaves everything to your children but your IRA beneficiary form still names your brother, your brother gets the IRA. Courts side with the financial institution’s records every time a valid beneficiary form exists. This covers life insurance, 401(k)s, IRAs, annuities, and any account with a payable-on-death or transfer-on-death designation. Your will only governs assets without a separate beneficiary designation.
Business Ownership
If you own a business, estate planning doubles as succession planning. A buy-sell agreement sets out what happens to your ownership interest if you die, become disabled, or want to exit. It creates a guaranteed buyer and a predetermined price or pricing formula. Without one, your family may inherit an interest they can’t sell, or your co-owners may find themselves with a new partner they didn’t choose. Operating agreements, partnership agreements, or corporate bylaws should coordinate with the rest of your plan.
Funding the Trust You Already Set Up
Creating a trust document is only half the job. A trust controls nothing until you transfer assets into it. For real estate, that means recording a new deed with your county clerk, often with a certificate of trust and sometimes with lender consent if there’s a mortgage. For financial accounts, you retitle the account in the trust’s name or name the trust as beneficiary. Stocks, bonds, and business interests each have their own transfer procedures. An unfunded trust won’t avoid probate or protect anything.
Health and Aging
Incapacity Planning
Your 50s and 60s make incapacity planning feel urgent, but a serious diagnosis at any age creates the same need. A durable financial power of attorney lets someone you trust pay the mortgage, manage investments, and handle tax filings. A healthcare power of attorney, sometimes called an advance healthcare directive, lets someone make medical decisions for you. Both must be signed while you’re mentally competent. Once capacity is lost, the only option is a court-supervised guardianship proceeding.
The Medicaid Five-Year Look-Back
If nursing home care becomes necessary, Medicaid may help cover the cost, but only after reviewing your financial history from the previous five years. Assets transferred for less than fair market value during that window — gifts to children, property transfers to family, below-market sales — can trigger a penalty period during which Medicaid won’t pay for your care.2Office of the Law Revision Counsel. United States Code Title 42 – Section 1396p The penalty equals the total value of improper transfers divided by the average monthly cost of nursing home care in your state. A $100,000 gift made three years before you apply could leave you without coverage for months. Planning around the look-back means starting at least five years before you anticipate needing care.
What Waiting Costs You
Dying without a will is called dying intestate, and it means the state writes your estate plan for you. Every state has intestacy laws that distribute assets along a rigid hierarchy, typically spouse, then children, then parents, then siblings, then more distant relatives. The formula varies by state and rarely matches what people actually want. An unmarried partner gets nothing. A favorite charity gets nothing. A stepchild you raised but never legally adopted gets nothing. If no living relatives can be found, the entire estate eventually goes to the state through a process called escheatment.
Even when relatives do exist, the absence of a will almost guarantees probate, where court filing fees, attorney costs, and executor compensation can consume a meaningful share of smaller estates. Probate is also public. Anyone can see what you owned and who received it.
Digital Assets Deserve Their Own Line
Cryptocurrency wallets, online business accounts, domain names, cloud-stored photos, social media profiles, and email accounts now carry real financial and sentimental value. Most states have adopted the Revised Uniform Fiduciary Access to Digital Assets Act, which gives your executor or trustee access only if you’ve either activated an in-platform setting authorizing disclosure or specifically granted access in your will or trust.
Keep a secure, updated list of your digital accounts, passwords, and two-factor authentication methods, and make sure your will or trust explicitly authorizes your representative to access digital accounts and electronic communications. Cryptocurrency is especially high-risk. There’s no institution to call. If nobody knows your private keys or seed phrase, those assets are permanently gone.
How Often to Review When Nothing Has Happened
Even without a triggering event, review your plan every three to five years. Tax laws change, relationships shift, assets grow or shrink, and the people you named as executors, trustees, or guardians may no longer be the right fit. A plan drafted ten years ago that nobody has touched since is only marginally better than no plan at all. The goal isn’t getting it perfect on day one. It’s building something you’ll actually maintain.
