When you make your last will and testament, you do so based on your current situation. Situations can change, though, with marriage, divorce, new children, and grandchildren. When big changes happen to your family, it’s time to think about updating a will.

Marital changes

Changes to your marital situation are one of the most common reasons for changing a will. Most states automatically give a portion of your estate to your spouse, whether you include them in your will or not, but you will likely want to decide for yourself what you want to leave your spouse. If you live in a state that recognizes common-law marriage and meet the legal requirements, your partner may be treated as a legal spouse for inheritance purposes. This means they could be entitled to inherit from your estate, even if you do not have a will.

A common-law marriage is a legally recognized marriage without a formal ceremony or license, provided certain conditions are met, such as living together and holding yourselves out as married. This is different from a “common-law property” system, which refers to how property is owned during a marriage.

Because inheritance rights depend on whether a valid marriage exists, a partner in a recognized common-law marriage may have the same rights as a formally married spouse. However, you may still want to create a will to specify how your assets should be distributed. Keep in mind that many states limit your ability to completely disinherit a spouse.

If you divorce, you will also want to change your will. Most states revoke provisions for divorced spouses in wills, but it is best to redo your will. Lastly, if your spouse passes away, you should create a new will choosing other beneficiaries for your estate.

New additions

Many states have provisions for what are called “after-born children,” children or grandchildren born after a will has been executed, taking the share that pre-born children get and dividing it equally among all children in existence when the will is probated. Despite this, it is better to create a new will if you have a new child or grandchild you would like to leave something to. If you have a new baby, you will want a new will so that you can name a guardian for that child, should you die while your child is a minor. Stepchildren do not automatically inherit from a stepparent, so if you become a stepparent and would like to leave something to a stepchild, you’ll need to revise your will.

Other changes

There are other situations that should prompt you to revise a will, such as if your beneficiary or executor predeceases you. Also, if there is a change in your financial situation—for example, if you sell a home or obtain unique or valuable new assets (such as meaningful jewelry or a valuable painting)—you may wish to update your will to leave the item to a specific person.

Revoking a will

If you are wondering how to change a will, the safest and most thorough way to make changes to a will is to make a new one, but you must also revoke the old will. To revoke a will, you include a written statement in your new will that you revoke all previous wills and codicils previously made by you. Copies of the old will should be destroyed once the new will is in effect, so that they can never be mistaken for a current will. Your new will must be executed and signed according to state law, and then it becomes the only valid will.

To properly revoke a will:

  • Include a revocation statement. Your new will should state that you revoke all previous wills and codicils.
  • Destroy old copies. Once your new will is in effect, destroy copies of the old will so they can't be mistaken for the current one.
  • Execute according to state law. Your new will must be signed and witnessed per your state's requirements to be valid.

Many people wonder what would happen if someone discovers an old will after their death. While the revocation clause in the new will makes previous versions legally invalid, destroying old copies prevents confusion and potential challenges from family members who might prefer the terms of an earlier document. Without a clear revocation clause, courts may attempt to reconcile multiple wills, which can create complications and delay settling your estate.

Updating your will without an attorney

You can update your will without hiring an attorney by using online legal services, will software, or state-specific forms. These DIY options can be cost-effective for straightforward changes like updating an executor, adding a beneficiary, or modifying how assets are distributed among existing heirs.

However, even self-prepared wills must meet all of your state's execution requirements to be valid. This typically includes:

  • Signing in the presence of the required number of witnesses (usually two)
  • Having witnesses sign the document
  • Notarization or a self-proving affidavit, where required by your state
  • Inclusion of proper revocation language to invalidate previous wills

While simple updates can be handled without professional help, complex situations benefit from legal guidance. If you have a blended family, significant assets, business ownership interests, or need tax planning strategies, an estate planning attorney can help you avoid costly mistakes. Improperly executed DIY changes can create ambiguity or even invalidate your will entirely, leaving your estate to be distributed according to state law rather than your wishes.

Altering a will

You cannot edit a will itself. Striking out clauses or writing in changes will result in you needing to write an entirely new document. So, if you need to make a small change to an existing will, such as changing your executor, you can execute a codicil to the will.

A codicil is an amendment to your old will that leaves the old will valid and in effect. A codicil can be used to alter or add a provision in your will, such as leaving your newly acquired boat to your grandson.

A codicil has to be executed and signed exactly as you would a will, but there is no standard codicil form. While it is a helpful tool, there are a few risks they bring up: The codicil could get separated from the will and lost or create will challenges, so they should be created with caution.

Your will should change with your life. Making changes to your will allows you to keep it current and ensure all of your wishes are carried out. It is important to know how to update a will in a way that is legal and carefully planned.

Cost of changing a will

The cost to change a will varies depending on the method you choose and the complexity of your updates. Understanding your options can help you decide whether to hire an attorney or take a more affordable DIY approach.

Here's what you can expect to pay:

  • Attorney-drafted new will. $300 to $1,000 or more, depending on your location, the attorney's experience, and the complexity of your estate
  • Attorney-prepared codicil. $100 to $500, though this only makes sense for minor changes
  • Online legal services. $20 to $150 for most basic will updates or new wills

Several factors affect the final cost. Attorneys in major metropolitan areas typically charge more than those in smaller towns. Complex estates involving trusts, business interests, or tax planning require more time and expertise. If you have assets in multiple states or a blended family with specific inheritance goals, expect to be on the higher end of attorney fees.

Because creating a new will and preparing a codicil often cost similar amounts when using an attorney, many estate planning professionals recommend drafting a new will rather than a codicil. A new will is cleaner, reduces the risk of lost documents, and eliminates confusion about which provisions remain in effect. For straightforward estates without complex planning needs, online services offer a cost-effective alternative that still produces a legally valid document.

Changing a will after the testator's death

Once the person who created the will (the testator) dies, the will becomes a fixed legal document. Generally, no one—including the executor, family members, or beneficiaries—can unilaterally change the terms of the will after death.

There are limited exceptions to this rule:

  • Family settlement agreements. In some states, if all beneficiaries agree, they can modify how assets are distributed through a written agreement. This doesn't technically change the will but alters how the estate is divided.
  • Court reformation. Courts may reform a will to correct clear mistakes, such as typos or obvious drafting errors, or to resolve ambiguous language that makes the testator's intent unclear.
  • Disclaimers. A beneficiary can refuse an inheritance, which causes the asset to pass to the next person named in the will or according to state intestacy laws.

Executors have a legal duty to follow the will as written. They cannot change who receives assets, alter the amounts distributed, or modify any terms based on their own judgment or family pressure. If an executor deviates from the will's instructions, they can be held personally liable and removed from their role.

Will contests are sometimes confused with changing a will, but they serve a different purpose. A will contest challenges the validity of the document itself, claiming it was signed under duress, the testator lacked mental capacity, or the will wasn't properly executed. A successful contest doesn't change the will; it invalidates it entirely, causing the estate to be distributed according to a previous valid will or state law.

FAQs on changing a will

Should I update my will when I get married?

Yes, you should create a new will that includes your spouse. While most states automatically give a portion of your estate to a spouse, updating your will ensures you decide exactly what to leave them.

What happens to my will if I get divorced?

If you divorce, you should update your will. Most states revoke provisions for divorced spouses in wills, but it's best to create a new will to ensure your estate is distributed according to your current wishes and to name other beneficiaries for assets previously left to your former spouse.

Do I need to update my will when I have a baby?

Yes, updating your will when you have a child allows you to name a guardian should you die while they're a minor. While many states have provisions for "after-born children," specifying your wishes ensures your child's care is clearly documented.

Should I include stepchildren in my will?

Stepchildren do not automatically inherit from a stepparent, so if you want to leave something to a stepchild, you must specifically include them in your will. Update your will to reflect your wishes for any stepchildren you want to provide for.

When should I update my will if my circumstances change?

Update your will if beneficiaries or your executor pass away, if your financial situation changes significantly, or if you acquire new valuable assets. If your will leaves property you no longer own, that beneficiary may inherit nothing unless you update the document.

Should I update my will when I move to another state?

Wills that are valid in one state are generally recognized in other states, but reviewing your will after a move is still a smart decision. State laws vary on execution requirements—some states require two witnesses while others require three, and notarization or self-proving affidavit requirements differ. More significantly, states handle property rights differently, particularly community property states versus common law states.

Consider consulting an estate planning attorney in your new state to ensure your will meets local requirements and takes advantage of any state-specific planning opportunities. You should also update your will if you've sold property mentioned in the document or acquired new real estate in your new state. Homestead protections, which affect how your primary residence passes to heirs, also vary significantly by state and may impact your estate plan.

I researched online Estate Planning and…

I researched online Estate Planning and decided I would go with Legal Zoom. I had heard commercials and watched YouTube videos, so it seemed like the perfect choice. I decided to go with the couples Pro? Version. It’s really easy to follow the questions and I found it to be quite simple to understand. I finished completing my questions and when I got to the end, I was asked to verify the answers for the printing and mailing. I wasn’t sure if I should finish that step because I had not answered any questions regarding my husband’s Will. So I decided to ask a question in the live Chat. I had the pleasure of chatting with Quience today. I wasn’t sure if I should complete my will, print and mail it or wait until I have completed my husband’s will. Quience advised me to proceed with printing and mailing my Will, and once I have completed it then I will be able to complete my husband’s Will. Quience also waited until I answered and completed my husband’s Will in the Chat just in case I needed further assistance. I can’t say enough great things about Quience. Oftentimes you just don’t feel as though the person that you are chatting with actually cares or wants to help you. I am very happy with my entire experience with Legal Zoom. If you have been putting off important decisions for your Estate Planning, consider Legal Zoom. I am so glad that I did!!!

I set up my Trust

I set up my Trust, Will, Health Directive, and Power of Attorney all at the same time with their estate plan. Incredibly easy. Of course I had to dig out all the info, but the input was simple and straightforward, and the free consults were priceless. Had I used an attorney alone, it would easily have cost me 3k+. Thanks Legal Zoom!
