Updating Your Wills and Estate Plan After Marriage, Divorce, or New Children


Your Will is probably useless the second you walk down the aisle. It is a controversial truth that most Australians simply refuse to accept until it is far too late for their beneficiaries. Professional negligence. Most people assume a legal document is a “set and forget” shield that lasts for forty years. It is a staggering reality that life moves much faster than the paper in your lawyer’s vault. Why?

A massive oversight. You might think your marriage automatically updates your legal status. The law in most Australian states actually works in the opposite direction by revoking your Will. It is gone.

The list of assets you currently own are often the result of decades of hard work. We often find that a single celebration can wipe out a decade of careful planning. Honestly! The coffee machine in our Sydney office is finally working again, which is a relief because these conversations require a lot of caffeine. It’s vital.

When you say I do…

Automatic revocation. Marriage generally cancels any Will made before the wedding date unless it was specifically drafted “in contemplation” of that marriage. You must act.

Many couples believe they are protected because they share a bank account or a mortgage. The actual real-life truth is that your parents or siblings might inherit your estate instead of your new spouse if you die without an updated document. It is a complete mess. Gosh! You need a new Will that explicitly names your partner as the primary beneficiary to avoid this outcome. Do it now.

One mistake. I have seen families torn apart because a husband died three weeks after a wedding without updating his paperwork. The sum total of the whole amount of his estate went to a brother he had not spoken to in years. It was tragic.

Dealing with a divorce…

Legal limbo. While marriage revokes a Will, a divorce usually only revokes the parts of the Will that mention your ex-spouse. This is tricky. (The parking at the Parramatta courts is still a nightmare lately, by the way).

Actually, I was reviewing a file; wait, that’s not for public consumption; let’s stay focused on the risks. If you are separated but not yet legally divorced, your “ex” might still be entitled to everything you own. Ugh! This period of separation is the most dangerous time for your family’s financial security. Update it.

The sum total of the whole amount of your wealth could end up in the hands of someone you are currently fighting in the Family Court. You need to appoint a new executor and name new beneficiaries the moment you move out of the shared home. It is a protective measure. Most people wait until the final decree is issued, but that is often six months too late. Stay sharp.

When children arrive unexpectedly…

Guardianship needs. The birth of a child changes the “actual real-life” priorities of your estate plan from asset distribution to long-term care and protection. Essential step.

You need to nominate a guardian who will raise your children if both parents are no longer around. Without this specific clause, the state government or a judge will decide who gets custody of your kids. This is terrifying. Each of the guardians you choose have to be consulted before you put their name on the dotted paper. Don’t guess.

A heavy burden. You also need to consider at what age your children should receive their full inheritance. Most parents realize that an eighteen-year-old with a million dollars is a recipe for a very fast car and a very short-lived legacy. It’s common sense. You can use a testamentary trust to stagger the payments over several years. Smart move.

Changing your executor choice…

Reliability matters. The person you chose ten years ago might no longer be the right person to manage your complex financial affairs or your business. Be picky.

The group of executors you pick is—actually, I should say “are”—the most important part of the entire probate process. If they have moved overseas or have become too elderly to handle the paperwork, your estate will stall. It’s a grind. You need someone with a cool head, a sharp eye for detail, and the patience to deal with banks. Pick well.

The law is simple.

Total disaster. I once saw a best mate try to manage an estate while dealing with his own bankruptcy, which led to a total freeze on the family’s cash flow. It was a dog’s breakfast of a situation that could have been avoided with a quick update. Don’t be that person. Trust is good, but competence is better when it comes to the law. Always.

Protecting the family legacy…

Blended families. If you have children from a previous relationship and a new spouse, you are walking a legal tightrope that requires expert navigation. It is hard.

You have to ensure that your current partner is looked after while also “ring-fencing” assets for your biological children. The reality of modern life is that these competing interests often lead to a Family Provision Claim in the Supreme Court. It is pricey. A lawyer can help you use life interest clauses, trusts, and specific gifts to keep everyone happy and out of the witness box. It works.

Final end result. At the end of the day, your estate plan is a living document that needs to grow as your family grows. It is about finding a solution that respects your past while protecting your future. It’s time.

Actually, the past history of these cases shows that the most prepared families are the ones who treat their lawyer like a partner, not a one-time service provider. It’s a win.
