Why the Most Well-Intentioned Promise About Your Will Might Not Help Your Children

When love and legal planning collide in blended families

Picture this: You’re sitting around the kitchen table with your new partner, both of you
wanting to do the right thing by everyone. You’ve both got children from previous
relationships, and you’re determined that this time, everyone will be looked after fairly. So
you make what seems like the perfect promise to each other: “Let’s both agree never to
change our wills without the other’s written consent. That way, we can be sure our kids
won’t miss out.”

It sounds like the ideal solution, doesn’t it? A mutual wills agreement that protects everyone
and prevents any future partner from changing their mind and leaving your children with
nothing.

Here’s what might surprise you: this well-intentioned promise often becomes the very thing
that prevents you from helping your children when they need it most.

The Reality of Life After Loss

It is not uncommon for blended family couples to make mutual wills agreements with the
best of intentions, but life rarely follows our carefully laid plans. The following two scenarios
illustrate just how things can turn out unexpectedly.

Scenario one: Two partners in their 40s create a mutual wills agreement. Sadly, one passes
away unexpectedly. The surviving partner, bound by that promise never to change their will,
remarries and enjoys 25 wonderful years with their new spouse. When they eventually pass
away, their devoted partner of 25 years finds themselves without a home because the
original will couldn’t be changed to provide even basic security.

Scenario two: A parent has agreed they can’t change their will, but one of their deceased
partner’s children develops serious addiction problems. The surviving parent watches
helplessly, unable to alter the will to put that child’s inheritance into a protective trust that
could actually help them through their struggles.

When Good Intentions Create Unintended Consequences

These aren’t rare exceptions. They’re the reality of what happens when we try to solve the
complex puzzle of blended family inheritance with a rigid legal structure that can’t adapt to
life’s changes.

The fundamental problem with mutual wills agreements is that they’re designed to prevent
injustice, but often end up creating it instead. Life moves forward, circumstances change,
and relationships evolve, but your will remains frozen in time.

Understanding What You’re Really Agreeing To

When you sign a mutual wills agreement, you’re essentially promising that once your
partner dies, you’ll never change your will, no matter what happens. That means:

• You can’t help a struggling child by creating a protective trust
• You can’t provide security for a devoted long-term partner
• You can’t adapt to major life changes or family crises
• You can’t even make small adjustments that might benefit your deceased partner’s
  children

The very inflexibility that seems protective becomes a straightjacket that prevents you from
responding to your family’s real needs as they arise.

Better Ways to Protect Your Children

The good news is that there are more flexible approaches that can protect your children
without trapping your surviving partner in an unchangeable arrangement.

Superannuation Strategies: Your superannuation doesn’t automatically follow your will. You
can use binding death benefit nominations to direct your super straight to your children,
while leaving other assets like your home to provide security for your partner.

Asset Splitting: Rather than leaving everything to your partner and hoping they’ll honour
your wishes, you can strategically divide different types of assets. This gives your children
direct inheritance of some assets while ensuring your partner has security.

Professional Guidance: Every blended family situation is unique. What works for your
neighbours might not work for your family’s specific circumstances and assets.

The Conversation That Matters

Instead of focusing on legal mechanisms to force future compliance, consider having honest
ongoing conversations with your partner about intentions and concerns. These discussions,
while sometimes difficult, often provide more security than legal contracts because they’re
based on understanding rather than obligation.

Moving Forward With Confidence

We understand that navigating blended family inheritance feels overwhelming. You want to
do right by everyone, and that desire is exactly what makes you a caring partner and parent.
The key is finding solutions that provide protection without creating new problems. This
means understanding all your options, considering your specific circumstances, and
choosing flexible strategies that can adapt as your family’s needs change.

If you’re in a blended family situation and wondering how to protect everyone you care
about, we’re here to help you explore options that actually work for your unique
circumstances. Because protecting your family shouldn’t mean creating new problems for
them down the track.
