Updating Your Will After Separation: Why It Matters for Your Future

As family lawyers, we understand that separation can be one of life’s most emotionally charged and destabilising experiences. Amid the practical and personal upheaval, reviewing your will may not feel urgent—but it absolutely should be. If you’re separated but not yet divorced, your former partner may still have a significant legal claim over your estate.

This article explains why updating your will post-separation is more than just a legal formality—it’s a vital step to protect your assets, clarify your wishes, and give peace of mind to you and your loved ones.

Why a New Will Is Essential After Separation

When you separate but remain legally married, your spouse remains your primary legal beneficiary—whether that aligns with your current wishes. Under Australia’s laws of intestacy (which apply when no valid will exists), a surviving spouse often inherits the bulk of the estate by default. Even with an existing will, if your ex-partner is still named as the main beneficiary or executor, they may retain those roles unless the document is updated or revoked.

It’s important to remember that separation alone doesn’t diminish your spouse’s legal entitlements. Until a divorce is finalised, or a new will is executed, your ex-partner may be in a position to inherit everything.

The Role of Financial Settlements in Estate Planning

You might assume that finalising a financial settlement with your former partner resolves all financial ties—but that’s only part of the story. Unless you update your estate planning documents, including your will and superannuation nominations, your ex-spouse could still benefit from your estate.

Unlike a marriage, which automatically revokes a will, divorce has a more nuanced impact. In most Australian states, divorce revokes any clauses in a will that refer to the former spouse (e.g., as executor or beneficiary), but the rest of the will remains valid. Separation, on the other hand, doesn’t affect your will at all. That’s why it’s critical to act early and clearly outline your post-separation intentions in a new, legally binding document.

Separation vs. Divorce: What the Law Says About Wills

It’s a common misconception that separation offers the same legal protections as divorce when it comes to estate planning. It doesn’t. Legally, separation changes your relationship status but does not alter the rights your spouse has under a will or intestacy laws.

Only a divorce decree changes your spouse’s status in this context—treating them, in most cases, as though they had predeceased you for inheritance purposes. Until that point, the onus is on you to update your will and related documents to ensure they reflect your current circumstances and preferences.

Next of Kin and Medical Decision-Making

Your will isn’t the only document that needs review. If you’re separated, your former partner may still be considered your next of kin. This status can impact not only inheritance but also major medical decisions if you become incapacitated.

We encourage clients to consider updating or revoking any existing Powers of Attorney or appointing someone new to act on your behalf for financial or medical decisions. Ensuring your legal documents are aligned helps avoid future disputes and gives you confidence that your choices will be respected.

What you need to do

We know that life after separation is filled with uncertainty. But updating your will doesn’t need to be complex—it’s a simple, proactive step that can prevent confusion, conflict, and unintended outcomes down the road.

Whether you’re planning for your children, a new partner, or other loved ones, a clear and current will offers clarity and reassurance. It ensures that your estate is distributed as you intend and that those closest to you are supported in the way you choose.
