This article is part of our Estate Planning Essentials series, where we explore the practical steps you can take to protect your loved ones and ensure your wishes are carried out. In this blog we cover how to protect vulnerable family members through proper estate planning. In future blogs, we explore how to choose the right people to manage trusts and what happens to your will after major life changes.
Careful estate planning – including properly structured wills and trusts – is essential when providing for a vulnerable beneficiary.
We’re hearing more and more about rising diagnoses of autism, additional needs and other vulnerabilities in society, particularly among younger generations.
Some of this comes down to greater awareness and recognition, which is a positive step. But it also raises important questions for families: how do we make sure vulnerable loved ones are protected, especially when it comes to inheritance and future care?
Why an experienced approach matters
When people make wills without specialist advice, three patterns often crop up:
- Leaving more to a vulnerable child or relative in the hope that extra money will cover their future needs.
- Excluding them altogether out of fear that an inheritance could disrupt their benefits or be difficult for them to manage. Families often expect other beneficiaries to ‘do the right thing’ and help out, but this is not legally binding.
- Overlooking wider planning – for example, wills that automatically pass assets down to grandchildren without considering whether a grandchild may also have additional needs.
None of these options are particularly safe or reliable. They can create more problems than they solve.
Why goodwill isn’t enough
Relying on other family members to ‘share’ an inheritance is risky. Not only is it unenforceable, but it can also have tax consequences for those involved. While it may be possible to fix some problems after the event with a deed of variation, that relies on everyone agreeing and on strict time limits being met.
A far safer route is to plan ahead using the right legal structures.
The role of trusts
One of the best tools for protecting vulnerable beneficiaries is a trust. These can be created in your lifetime or written into a Will. They allow money to be managed and used for someone’s benefit without being handed to them directly – protecting both the person and the funds.
Certain types of trusts, such as disabled person trusts, may also bring tax advantages if they meet legal criteria. While the rules can be complex, the main purpose is not tax saving. It’s about ensuring future care and financial support in a safe, controlled way.
Planning beyond the paperwork
Estate planning for vulnerable people is never just about money. Practical issues matter just as much:
- Where will your loved one live when you’re no longer around?
- Who will manage their care or step in if they cannot make decisions?
- Who should act as trustees – and should they be impartial?
- Is there a plan for care assessments and regular reviews?
These are deeply human questions. That’s why good estate planning often involves not only lawyers and accountants, but also social services, care providers, and trusted family members or friends. Together, they can create a support system that lasts long after parents or carers are gone.
Protecting vulnerable family members isn’t something that can be left to chance, goodwill or a basic will. With the right structures in place – especially trusts – families can provide peace of mind and security for generations to come.
