How To Change A Will In Singapore - A Simple Guide You Can Trust

Life has a way of throwing surprises at us. A new child is born, relationships shift, or you go through a Divorce, and suddenly, your old will doesn’t reflect your current wishes. That’s where knowing how to change a will becomes important.

Whether you’re rethinking who gets what or simply updating your executor, changing your will isn’t as complicated as it may seem, but it does need to be done properly. In Singapore, there are specific laws that make sure any changes you make are legal, fair, and valid.

Let’s walk you through the ins and outs of how to change a will in Singapore, so you can protect what matters most and have peace of mind knowing everything’s in place.

There are two main ways you can change your will under Singapore law:

 

1. Create A Codicil

Create A Codicil

This is a legal document that allows you to make minor changes to your will, for example, updating an executor or changing a specific gift. A codicil must:

  • Be signed in the presence of two witnesses (just like a will)
  • Refer clearly to the original will

It’s best to keep codicils simple. If you’re making several changes, it might be easier and safer to just write a new will.

 

2. Make A New Will

For major changes, like redistributing your estate or removing someone, it’s often more straightforward to revoke your current will and create a new one.

To do this properly, your new will should:

  • Clearly state that it revokes all previous wills
  • Be signed and witnessed according to Singapore’s Wills Act

Once your new will is signed, the old one becomes invalid.

 

When Should You Think About Changing Your Will?

When Should You Think About Changing Your Will

You might not think about your will very often. But there are key moments in life when it’s worth revisiting:

  • You’ve gone through a Divorce or marriage
  • A loved one named in your will has passed away
  • You’ve had children or grandchildren
  • You want to change your executor or guardian
  • Your financial situation has changed
  • You’ve had a change of heart about who should inherit

In Singapore, a marriage automatically revokes an existing will (unless the will was made in anticipation of the marriage), and Divorce doesn’t automatically cancel it, which catches many people off guard. That’s why it’s important to review your will regularly.

 

Conclusion About Changing A Will

Your will is one of the most important documents you’ll ever write. If it’s out of date or unclear, it could cause stress for your loved ones or, worse, end up in a dispute before the Court.

Knowing how to change a will gives you control over your legacy, your assets, and your peace of mind.

Frequently Asked Questions About Changing A Will

Does A Divorce Automatically Cancel My Will?

No, Divorce does not revoke your will in Singapore. You’ll need to update it yourself if your wishes have changed.

Can I Just Write Changes To My Existing Will?

No, handwritten changes without proper witnessing are not legally valid in Singapore. Always make changes through a codicil or by creating a new will.

Who Can Witness My Will Or Codicil?

Two independent witnesses are required. They must be at least 21 years old and cannot be beneficiaries in the will or their spouses.

Is A Lawyer Required To Change A Will?

While it’s not legally required, it’s highly recommended to engage a lawyer to ensure your will or codicil is valid and reflects your intentions clearly.

What Happens If I Don’t Change My Will After Marriage Or Divorce?

Marriage revokes a will unless it was made in contemplation of that marriage. Divorce does not, so it’s important to review and update your will after major life events.
