Making Your Own LPA Can Be Easy. Making One That Survives Challenge Is Where Things Go Wrong

Many people decide to create a Lasting Power of Attorney themselves. The forms are accessible, the guidance looks clear, and on the surface the process feels straightforward. For a lot of people, this leads to the view that professional involvement is unnecessary.
Filling in the forms usually is easy. The risk sits elsewhere. It sits in the part of the process that only matters later, when you may no longer be able to explain or defend your decisions yourself. That part is the certificate provider.
Why the certificate provider matters in DIY LPAs
The certificate provider is not there to help with the paperwork. Their role is to confirm that you understand what you are signing and that you are doing so freely.
They must be satisfied that you:
- Understand what an LPA is and what powers you are giving to your attorneys
- Understand the consequences of those powers being used
- Are not being pressured or influenced by anyone else
In DIY LPAs, this role is often treated as a formality. A friend or acquaintance is chosen because they meet the two-year rule and are convenient. The courts have repeatedly shown that this is where LPAs fail.
Real court cases where DIY-style certification caused LPAs to be overturned
TA v The Public Guardian (Court of Protection, 2023)
In this case, a woman cancelled an earlier LPA and made new ones appointing only one of her children as attorney. A long-standing friend acted as the certificate provider. The LPA was later challenged by another family member.
The Court of Protection examined whether the woman understood what she had signed at the time. The court concluded that she did not have the required mental capacity and that the certificate provider had not properly satisfied themselves that she understood the nature and effect of the LPA or that she was acting freely.
The LPAs were declared invalid. The court made it clear that familiarity with the donor did not compensate for a lack of proper assessment. This case is now frequently cited as a warning that informal certification is not enough.
The case of a 92-year-old donor with a family friend as certificate provider
In another reported case, a woman in her nineties made property and welfare LPAs appointing only one of her children. A family friend acted as certificate provider.
During a later investigation, it emerged that the certificate provider had asked very limited questions and had not explored whether the donor genuinely understood the scope and long-term effect of the LPAs. The assessment was based largely on assumption rather than evidence.
The judge ruled that the certificate provider had not carried out their legal role properly. The LPAs were declared invalid, and that decision was upheld on appeal. Once again, the issue was not the form itself but the way the certificate provider approached their responsibility.
What these cases tell us about “easy” LPAs
Both of these cases involved LPAs that were correctly completed and registered. They failed because the certificate provider could not demonstrate that they had properly assessed understanding and free will.
This is the hidden risk in DIY LPAs. The process feels simple, but if the LPA is later questioned by family members or reviewed by the , the certificate provider may be asked to explain what they did and why they were satisfied.
Many people who act as certificate providers in DIY LPAs are not prepared for that level of scrutiny.
Where professionals still matter, even if you do the rest yourself
Using a professional as certificate provider does not mean you cannot complete your own LPA. Many people do exactly that. They fill in the forms themselves and involve a professional only for the certification.
Professionals such as solicitors or doctors are trained to assess mental capacity and understanding. They know how to ask the right questions and how to record their reasoning in a way that stands up to later challenge. They are also regulated and accountable.
If the LPA is ever questioned years later, a professional certificate provider is far more likely to be able to explain and justify their decision.
The point many DIY LPA guides do not make
Creating an LPA can be easy. Ensuring it works when it matters is a different issue.
The certificate provider is not there to make the process smoother today. They are there to protect your wishes at a time when you may no longer be able to speak for yourself.
The court cases above show that when this role is treated lightly, LPAs can fail completely. By the time that happens, it is too late to fix.
Choosing a professional certificate provider is not about making an LPA complicated. It is about making sure that the LPA you create actually does what you intended when it is needed.
