How to Make a Last Will and Testament in Oklahoma (2026)

Making a will might sound like something you can put off, but it’s one of the most important things you can do for your loved ones. A will lets you decide what happens to your property and who takes care of your kids. Without one, the court makes those decisions for you. Luckily, learning how to make a last will and testament is straightforward with just a little guidance from an estate planning attorney.

What Is a Last Will and Testament?

A last will and testament is a legal document that explains what you want to happen to your property and family after you die. In your will, you can name who gets your home, money, car, or other personal items. You can also choose a guardian for your minor children and name someone to care for your pets.

Your will makes things clearer for your loved ones and can help prevent arguments. Without a will, the state decides who gets what, and it might not be what you wanted.

How to Make a Last Will and Testament

Making a will takes some thought and planning. Each step below helps make sure your wishes are clear and your family is taken care of.

Choose a Guardian for Children

If you have children under 18, choosing a guardian is one of the most important parts of your last will and testament. A guardian is the person who would raise your kids if something happened to you. You’ll want to pick someone who shares your values, is financially stable, and has a good relationship with your children.

Before listing a guardian in your will, talk to the person first to make sure they’re willing to take on the responsibility. You can also name a backup guardian in case your first choice can’t do it. Naming a guardian gives you peace of mind and avoids family disputes later on.

Decide What to Include

Think about everything you own, including your home, cars, bank accounts, investments, and personal items like jewelry or heirlooms. These are all part of your estate and can be listed in your last will and testament.

Some items, like retirement accounts or life insurance, already have named beneficiaries. Those pass outside of the will, so check to make sure those names are up to date. Also, keep in mind that you don’t need to put jointly owned property with rights of survivorship in your will. Review each asset to decide where it belongs.

Decide Who to Give It To

Once you’ve made a list of your assets, decide who should receive each one. These people are called your beneficiaries. They can be family members, friends, or even charities.

Be as clear as possible in your will so there’s no confusion. For example, instead of saying “my car,” write “my 2022 Ford Explorer.” This helps make sure your things go to the right people and reduces the chance of arguments or mistakes.

Choose an Executor

Your executor is the person who makes sure your wishes are followed after you pass. They’ll handle tasks like paying your bills, filing taxes, and giving out the property listed in your will. Pick someone you trust who’s responsible and good with details.

You can name a friend, family member, or even a professional like an attorney. Make sure to talk to the person first to see if they’re comfortable with the job. You can also name an alternate in case your first choice can’t do it.

Write Your Will

Now that you’ve made your decisions, it’s time to write the will. It should include your name, a statement that this is your last will and testament, your executor’s name, the names of any guardians, and a clear list of who gets what.

You can write it yourself, but working with an attorney makes sure your will is valid and complete. An attorney can also help you avoid common mistakes and explain anything you’re unsure about. The small cost now can save your family time, stress, and money later.

Sign Your Will

In Oklahoma, you must sign your last will and testament in front of two witnesses. Your witnesses must also sign it in front of you. It’s best to choose witnesses who aren’t named in the will, which means they don’t get anything from it. This helps avoid legal challenges after you pass away.

You don’t need to have your will notarized in Oklahoma, but doing so can help with the probate process later. While it won’t avoid probate, it can speed it up because the court won’t have to find and verify the witnesses.

Store the Will in a Safe Place

Once your will is signed, keep it somewhere safe. A fireproof safe in your home or a safe deposit box at the bank are good options. Make sure your executor knows where to find it.

Avoid hiding it in a place that’s hard to reach or where someone might accidentally throw it away. You might also give a copy to your attorney who helped draft your will. The key is making sure the right person can find it when the time comes.

Update It Regularly

Life changes, and your will should change with it. You might get married, have a child, move, or gain new property. Every few years—or after a big life event—read over your will to see if anything needs to be updated.

You can make small changes with a document called a codicil, or you can write a new will. Keeping it up to date helps make sure your wishes are always clear.
