3 ways behavioural bias could affect your approach to estate planning

Financial biases are often linked to investing. However, subconscious tendencies can affect many aspects of your finances, including your estate plan.

An estate plan sets out how your assets will be managed during your lifetime and distributed after your death. It might include writing a will or creating a trust to provide for young children.

As estate planning can be emotional, it’s not surprising that behavioural biases could affect how you approach the task. So, here are three ways biases might affect your estate plan.

1. Putting off your estate plan due to emotions or overconfidence

Trying to avoid confronting difficult emotions means some people put off estate planning altogether.

A February 2025 survey carried out by JMW Solicitors found that 77% of people believe having a will is important. Yet, 58% don’t have a valid will, and avoiding the sometimes difficult conversations that might form part of estate planning could be a reason why.

Overconfidence may also be a reason for not creating an estate plan. For example, you might believe you’re “too young” to worry about writing a will or that you’re healthy now, so you can leave the task for the future. However, life is unpredictable and it’s impossible to know what’s around the corner.

Putting off estate planning because it’s difficult or you assume you don’t need one yet could leave your family in a vulnerable position should the unexpected happen.

While estate planning can be daunting at first, view it as a step that allows you to take control of your legacy. Once the task is complete, you may find it reassuring to know you’ve set out your wishes.

2. Under or overvaluing assets could have implications for your estate plan

A common financial bias that affects investors is tying the value of certain assets to a particular piece of information. For example, you might view shares as being worth £100 because that’s what you initially paid for them, even if the value has changed.

Under or overvaluing your assets could have implications for your estate plan.

You might want to split your estate evenly between your children while giving them specific assets. However, if you don’t have accurate information when doing this, they could end up with very different proportions of your wealth, which might lead to disputes.

Alternatively, if you undervalue assets, you might not realise your estate could be subject to Inheritance Tax (IHT). For instance, if you’ve “anchored” the value of your home to the price you paid for it 20 years ago, your estate could unexpectedly be liable for IHT due to rising property prices.

Regular financial reviews with your financial planner can help you track the value of your assets, and how they could rise or fall in the future.

3. Loss aversion could mean you are reluctant to pass on assets

Loss aversion suggests that you feel the pain of a loss twice as strongly as the pleasure of an equivalent gain. This bias can lead to people avoiding taking action, even when it would make sense.

As part of your financial plan, you might want to gift assets to your beneficiaries now instead of leaving them an inheritance. It’s an option that could provide much-needed financial support to your loved ones, such as covering university fees or helping them renovate their home.

Gifting during your lifetime can be rewarding, but loss aversion might also mean you’re reluctant to part with assets.

A reason for this is that you might worry about an unexpected event creating a financial shortfall in the future. So, you choose to hold on to the assets.

A financial plan could help you see the effect of gifting during your lifetime, including whether you could still overcome a financial shock. Discussing your gifting plans could give you the confidence to pass on assets and ease your worries.

Our former financial adviser was retiring and recommended Ray to us. He alleviated the constant worry of where to best invest our savings without too much risk. We’re very pleased with the results over the last 10 years. He explains things in layman's language, which we appreciate, and gives us the confidence we have made the right choices. What more can people expect?

Kathleen

We had pension policies and investments that needed sorting out ready for retirement. We didn't know what to expect from a financial adviser. We assumed that he would simply advise us where to get the best deals. How wrong we were. Ray took us right back to basics. He made us carefully consider what we really wanted to achieve. He has allowed us to start to really enjoy our retirement.

Michael

I needed financial advice about pensions and investments as I approached retirement. My wife was in the same position. Ray Martin worked out a comprehensive plan for putting my pension provision and savings into proper order. He did the same for my wife. He has continued to provide us with advice ever since. Ray is always straightforward, open and proactive.

Laurence

I was approaching retirement and wanting to look into limiting taxation and Inheritance Tax, as well as providing for my wife. Ray provided sound advice to switch from my current arrangement to a Drawdown Pension and ISA investments. I have now retired and have started seeing the benefits of his advice. The returns on my portfolio have increased beyond expectation. Ray performed extremely well.

Demetri

I had sold my house and didn't know how to invest the money. Ray invested very wisely and there has been about a 5% increase every year. He listened to our queries, gave answers that we fully understood and followed any requests. He always had time for us, and never rushed us. We would have been financially at a loss without his help.

Brian

Ray has been advising my wife and me for about 20 years. He is everything one could hope for in a financial adviser: wonderfully enthusiastic, extremely well informed, completely trustworthy and scrupulously observant of the regulatory requirements. He is able to explain complex matters very clearly, and so far, his advice has always been first class.

Oliver

I had money to invest and had no idea how to go about investing it and hopefully making a gain. I have three children and wanted advice about inheritance planning. Ray is very patient, very clear when he explains things, he is very interested in me as a person, totally trustworthy and is an excellent listener. We have never been disappointed! He`s been brilliant.

Rosie

I had just been widowed. Ray sorted out and simplified what was a very complex set of investments into a much less confusing portfolio. I have been extremely happy with everything Ray has advised over the last 12 years. Whilst moving with the times, he has dealt with all aspects of my investments wisely and given me all the guidance and help I have needed.

Pat

As the financial director of a company, I was seeking to get advice on how to plan and invest for retirement. Without a doubt, Ray Martin helped me understand and plan how to fund my retirement. Ray has been with me every step of the way. His advice has been invaluable. I retired and achieved my annual income goal. His continued advice is helping me in the next stage of my life.

Mike

I needed some advice regarding my late mother’s estate. I had also retired and required advice on how to manage my private pension. Ray was extremely helpful, and his advice was very clear and easy to understand. I came away from our initial meeting feeling very relieved and less stressed. We have just had our first yearly review and I was surprised how well my investments had done.

Jane

In the last 10 years, my circumstances have changed with the passage of time. Ray has guided me on how to protect and make my money grow. He listens carefully to my needs and gives clear, concise advice in a professional manner. He and his team are always accessible and patient with my questions and their approach gives me confidence that my finances are securely looked after.
