Estate Planning Study Guide: Protect Your Money & Wishes

(Wills, Power of Attorney, Living Wills – Real-World Money Skills)


What This Is

Estate planning isn’t just for rich people—it’s how you make sure your money, property, and even your medical wishes are handled the way you want if you can’t speak for yourself (like after an accident or death). Without it, the government decides who gets your stuff, who takes care of your kids, or whether you’re kept alive on machines. Example: If you die without a will, your state’s laws might split your savings between your spouse and your parents—even if you’d rather your spouse get everything. Or, if you’re in a coma, doctors might keep you alive for years against your wishes unless you’ve put it in writing.


Key Terms & Formulas

  • Will (Last Will and Testament): A legal document that says who gets your stuff (money, house, car, etc.) and who takes care of your kids after you die. Example: "I leave my $10,000 savings to my sister and my guitar to my best friend."
  • Executor: The person you pick to carry out your will (pay bills, distribute stuff, file taxes). Example: "My brother is my executor—he’ll handle selling my car and giving my niece my jewelry."
  • Beneficiary: The person (or charity) who gets your money or property. Example: "I named my daughter as the beneficiary of my life insurance policy."
  • Probate: The court process that proves your will is valid and oversees the distribution of your stuff. Example: "If I don’t have a will, my family has to go through probate, which can take months and cost thousands in legal fees."
  • Power of Attorney (POA): A legal document that lets someone else make decisions for you if you’re unable to (like if you’re in a coma). Example: "I gave my spouse POA so they can pay my bills if I’m in the hospital."
  • Durable POA: Stays in effect even if you’re incapacitated. Example: "My durable POA lets my sister sell my house if I’m in a nursing home."
  • Medical POA: Lets someone make healthcare decisions for you. Example: "My medical POA lets my partner decide if I should have surgery."
  • Living Will (Advance Directive): A document that says what medical treatments you don’t want if you’re terminally ill or permanently unconscious. Example: "My living will says I don’t want to be kept alive on a ventilator if there’s no chance I’ll recover."
  • Trust: A legal arrangement where a trustee holds and manages your assets for your beneficiaries. Example: "I set up a trust so my kids get my money when they turn 25, not at 18."
  • Guardian: The person you pick to take care of your minor kids if you die. Example: "I named my parents as guardians for my 5-year-old son."
  • Intestate: Dying without a will. Example: "If I die intestate, the state decides who gets my stuff—maybe not who I’d want."
  • Estate Tax: A tax on the value of your stuff when you die (only applies to very large estates—over $13.61 million in 2024). Example: "Most people don’t owe estate tax because their estate is under the limit."

Step-by-Step: How to Set Up Your Estate Plan

1. Take Inventory of Your Stuff

  • List everything you own (bank accounts, car, house, jewelry, etc.) and its approximate value.
  • List debts (credit cards, student loans, mortgage).
  • Example: "I have $15,000 in savings, a $200,000 house with a $150,000 mortgage, and a $10,000 car loan."

2. Decide Who Gets What

  • Pick beneficiaries for your money, property, and personal items.
  • Name a guardian for your kids (if you have any).
  • Example: "I want my spouse to get the house, my sister to get my savings, and my best friend to get my record collection."

3. Choose Your Decision-Makers

  • Executor: Who will handle your will? (Pick someone responsible—like a sibling or close friend.)
  • Power of Attorney (POA): Who can make financial/legal decisions if you’re incapacitated?
  • Medical POA: Who can make healthcare decisions for you?
  • Example: "I picked my brother as executor, my spouse as POA, and my sister as medical POA."

4. Write Your Documents

  • Will: Can be done online (like LegalZoom or Rocket Lawyer) or with a lawyer. Cost: $50–$500.
  • Power of Attorney & Living Will: Free templates are available online (check your state’s requirements).
  • Example: "I used a free template from my state’s bar association for my living will."

5. Sign & Store Your Documents Safely

  • Most states require 2 witnesses (not beneficiaries) to sign your will.
  • Store originals in a fireproof safe or with your lawyer. Give copies to your executor and POA.
  • Example: "I kept my will in a safe deposit box and gave a copy to my brother."

6. Update Regularly

  • Review your estate plan every 3–5 years or after big life changes (marriage, divorce, kids, big purchases).
  • Example: "I updated my will after my daughter was born to name her as beneficiary."

Common Mistakes

  • Mistake: Not having a will at all. Correction: Even a simple will is better than nothing. Without one, the state decides who gets your stuff—and it might not be who you’d want.

  • Mistake: Naming only one beneficiary (no backup). Correction: Always name a contingent beneficiary in case your first choice dies before you. Example: "I named my spouse as primary beneficiary and my sister as backup."

  • Mistake: Forgetting to update beneficiary forms (like on life insurance or retirement accounts). Correction: Your will doesn’t override beneficiary forms—so if you get divorced but forget to update your 401(k), your ex could still get it.

  • Mistake: Picking an executor who’s bad with money or lives far away. Correction: Choose someone responsible, organized, and nearby (or willing to travel). Example: "I picked my sister instead of my brother because she’s better with money."

  • Mistake: Not telling anyone where your documents are. Correction: Your family needs to know where to find your will, POA, and passwords. Example: "I told my spouse where my safe deposit box key is."


Real-World Insights

You don’t need a lawyer for basic estate planning. Free or low-cost templates (like from Nolo or your state’s bar association) work for simple wills. But if you have a lot of assets, a blended family, or a business, see a lawyer.

Your will doesn’t cover everything. Retirement accounts (401(k), IRA) and life insurance policies go to the beneficiary you named on the account, not your will. Example: "I named my ex as my 401(k) beneficiary 10 years ago—if I die, they get it, even if my will says my kids do."

A living will-a regular will. A living will is about medical care (like "no life support"), while a regular will is about money and property.

Red Flag: If a "financial advisor" tries to sell you a trust right away, be skeptical. Trusts are useful for some people (like those with large estates or special needs kids), but most people don’t need one.

Money-Saving Tip: Some states let you handwrite your will (called a "holographic will")—it’s legal if signed and dated. Example: "I wrote my will on a piece of paper, signed it, and had two friends witness it—cost me $0."
