The Hidden Costs of Going at It Alone – What Can Go Wrong Without Legal Advice

The Hidden Costs of Going at It Alone – What Can Go Wrong Without Legal Advice

Think you can sort it out yourselves? You might be right – but here's what to watch out for

We get it. Sometimes you and your former partner are getting along okay. Maybe you’ve agreed on the big things, like who’s keeping the house or where the kids will live. It feels easier – and cheaper – to just write something down and move on. 

But here’s the thing: even with the best intentions, informal agreements can go wrong. And when they do, the fallout is often expensive, emotionally draining, and difficult to unwind. 

At O’Loan Family Law, we’ve seen first-hand what happens when people skip legal advice. So, here’s what we want you to know. 

1. Informal agreements aren’t enforceable

A handshake deal or an email about who gets what won’t hold up in court. If one party changes their mind – or circumstances change – there’s not much you can do unless your agreement is legally binding. 

You could end up: 

  • Losing access to your fair share of the property pool 
  • Being liable for debts you thought weren’t yours 
  • Facing disputes about the care of children, even years later 

2. Delays can cost you your rights

If you’ve already divorced, you only have 12 months to start property or spousal maintenance proceedings. Miss that deadline and you could lose your right to claim – even if you’re entitled to something. 

The same goes for parenting agreements. Without legal advice, you might miss red flags or changes in circumstances that need to be formalised. 

3. You might miss assets or overlook tax and super

Legal advice helps you spot the hidden traps: like forgetting to value superannuation properly, assuming everything is split 50/50, or not understanding capital gains tax implications. These things matter, and they can affect your future. 

4. DIY settlements can lead to long, costly disputes later

Many people come to us after their informal agreement falls apart. One party might stop following it. New partners get involved. Someone moves away. And suddenly the deal that once seemed simple is a source of stress and conflict. 

By the time they get legal advice, emotions are high and positions are entrenched. A simple agreement could have saved thousands in legal fees and years of anxiety. 

Here’s what good advice gives you instead

  • Certainty: Your agreement is binding, clear, and future-proof. 
  • Peace of mind: You know your rights and obligations, and you’ve protected yourself. 
  • Control: You’ve made decisions that are fair and informed – not rushed or one-sided. 

At O’Loan Family Law, we’re here to keep things simple, supportive and secure

Getting legal advice doesn’t have to mean going to court. We focus on amicable solutions and practical planning. Whether you’re still working things out with your ex or you’ve already separated, we can help you turn your agreement into something solid and safe.
