At What Age Should You Write Your First Will?

If you ask the average person when they plan to write a will, they usually give a vague answer like, "When I'm older," or "When I retire." The truth is, waiting until you have gray hair to start estate planning is one of the most dangerous legal mistakes you can make.

There is a massive misconception that wills are only for seniors or people who have accumulated decades of wealth. Because of this myth, millions of young professionals and new parents walk around completely unprotected, assuming the law will just "figure it out" if something unexpected happens.

So, exactly how old do you need to be? The legal answer is simple: 18 years old. But the practical answer has very little to do with the year you were born, and everything to do with the milestones in your life. Here are the five major life events that mean it is officially time to write your first will.

1. The day you turn 18 (The Legal Baseline)

The moment you turn 18, you are legally an adult. This means your parents instantly lose the legal authority to manage your money or make your medical decisions. If you are 19, in college, and get into a severe car accident, doctors cannot legally let your parents make life-or-death decisions for you without a court order - unless you have an Advance Healthcare Directive and a Power of Attorney.

2. When you get your first "real" job or bank account

Even if you are 24 and renting an apartment, you likely have a checking account, a savings account, or perhaps a small 401(k) through your employer. If you pass away unexpectedly, who gets that money? Without a will, state law dictates that it goes to your parents. If you would rather that money go to a sibling, a long-term partner, or a favorite charity, you must put it in writing.

3. When you move in with a long-term partner

If you are cohabitating with someone but are not legally married, you desperately need a will. The law does not recognize "boyfriends" or "girlfriends," no matter how many years you have lived together. If you pass away, your partner has zero legal right to your bank accounts, your car, or even the apartment you share, unless you specifically name them in a Last Will and Testament.

4. The day you bring home a pet

Under the law, pets are considered property. If you are a 20-something single person who just adopted a rescue dog, what happens to that dog if you are no longer around? Without a will, your pet could end up in a crowded shelter. A Last Will allows you to legally name a trusted guardian for your pet and even leave behind funds for their care.

• Identify a trusted friend or family member to take ownership.
• Leave specific instructions for their diet and vet care.
• Ensure they never end up in the foster system.

5. The moment you have a child

If you have skipped the first four milestones, this is the one that is non-negotiable. If you are 25 or 45, the day you become a parent is the day you must write a will. It is the only legal way to name a guardian for your children. If you do not name a guardian, a judge who doesn't know your family will decide who raises your kids if you and your spouse pass away.
