Does marriage or divorce affect a will?

How does marriage and divorce affect your will in Australia?

Your personal circumstances change throughout your life, and these changes can have significant legal implications for your estate planning. How major life events impact a will is something people often consider in relation to ensuring their wishes are carried out as intended.

When you marry, the law in Australia automatically revokes your existing will. This means that any will made before your marriage becomes invalid, even if you want the same arrangements to continue. This rule exists to prevent situations where a person marries but their old will, which may not account for their new spouse, is still legally binding.

Similarly, divorce and separation also affect your will. When a divorce is finalised, any provision in your will that benefits your ex-spouse is automatically revoked. However, the rest of your will remains valid. This protects you from accidentally leaving assets to someone you no longer wish to benefit.

The effect of marriage on will validity can be unexpected if you're not aware of the rules. For this reason, many people don't realise their will is no longer valid after they marry. An understanding of the legal relationship between marriage and wills, as well as the connection between divorce and wills, is something people often draw on when maintaining estate planning.

For people going through separation and wills, or considering how to update will after divorce, the timing of any update is connected to particular stages of the process. Property settlement arrangements during separation may also affect what you want to include in your will.

Key points

• Marriage automatically revokes your entire will, unless it was made in contemplation of that specific marriage

• Divorce revokes any provisions in your will that benefit your ex-spouse, but the rest of the will remains valid

• Separation doesn't automatically revoke your will, but you may wish to update it to reflect your changed circumstances

• Significant life changes are circumstances in which people often review their estate planning.

• People often make a new will after marriage or divorce so their current wishes are documented.

Common situations

Life events that trigger changes to your will are more common than you might think. An understanding of when and why action arises is something people often find helps avoid complications later.

You may need to consider updating your will if:

• You've recently married and your previous will is no longer valid

• Your marriage has ended and you want to remove your ex-partner from your beneficiaries

• You've separated and are working through a property settlement that may affect what you own

• You're in a blended families situation and want to clarify who receives your assets

• You've acquired significant new assets since your last will was made

• Your family circumstances have changed in other ways (birth of children, caring responsibilities)

• Some people wish to ensure their estate reflects their current priorities and relationships.

If a will is not updated after major life events, disputes can arise. For example, if you marry and don't make a new will, your entire previous will is revoked, meaning you may die intestate (without a valid will). This can lead to complications, delays in administering your estate, and potential family conflict over who should inherit.

Similarly, if you leave your ex-spouse in your will after divorce without realising the relevant provisions are automatically revoked, confusion may arise during estate administration.

What to consider

• How much time has passed since a will was made is one matter people often weigh up.

• Whether assets and debts have changed significantly is one matter people often weigh up.

• Whether a blended families situation is involved is one matter people often weigh up.

• What requirements apply to a valid will is one matter people often weigh up when making a new will.

• Whether life circumstances have altered wishes about beneficiaries, guardians, or executors is one matter people often weigh up.

• The cost and complexity of updating a will versus making a new one is one matter people often weigh up.

• Whether professional guidance is involved in ensuring the process is done correctly is one matter people often weigh up.
