Protect your wishes
Secure verifiable digital evidence of
your testamentary and mental capacity
Why does mental capacity matter?
Your wishes can be challenged by someone who thinks they should receive more from you.
They may well say you didn't know what you were doing when you made your will or LPA - that you lacked "capacity".
The court must decide on the evidence available whether you had capacity when you made your will or LPA.
Capacity Vault provides the evidence courts need. Seeing is believing.

Frequently asked questions
Who should make a Capacity Vault call?
Anyone can use Capacity Vault. The two main categories where you should use it are: (1) if you believe the wishes in your will may be challenged, and (2) if you have concerns around your testamentary capacity.
How long will it take?
Making your Capacity Vault recording should take approximately half an hour. Our tutorials take 3 minutes, setting up your account should take 5 minutes and your recording will take 20 minutes to half an hour. If your recording is interrupted you will have to start the whole recording again.
How much does Capacity Vault cost?
Setting up your account costs £150. The subscription costs £10 per year. You can update your recordings for free and recover the recording free of charge if you maintain your subscription. If you cancel your subscription we will keep your recording. You will have to make a fresh purchase if you make a further recording. Without a subscription we will charge an admin fee to release the recording. This admin fee is currently £190.
Who checks and tests the evidence?
We use AI to check your call whilst you are making it. This ensures that your voice can be detected whilst you are making the call. Once you complete the call it is stored securely. If your will is ever challenged then the parties challenging your will and the courts will check the evidence in full.
What happens during the process?
You’ll be taken through a short tutorial (it takes around 3 minutes). You’ll then set up an account so we can store your evidence. Finally we will record your Capacity Vault entry. The call can take up to 10-20 minutes. You should make the call alone and in one single session. If you have to stop the call (e.g. to answer the phone or go to the toilet) you will have to start afresh.
What happens after I complete my Capacity Vault call?
We store your Capacity Vault recording in our secure storage until it is needed. If you update your will you should make another Capacity Vault recording. Each time you make a recording you can download a certificate to keep with your will.
Can I watch my call back?
Capacity Vault does not have a playback function. This has been done on purpose. We need to make sure that we gather and store a true representation of your mental capacity. That is why we ask you to make the call in one take and on your own. Once the call is made we will store the evidence we take on our secure servers. If your call is interrupted for any reason you can start again but you will have to answer every question.
What are the computer/ device requirements?
Your computer or other device (e.g. a mobile phone or tablet) must have a sufficiently strong connection to the internet (minimum 5kbps). You must have an up to date operating system (Apple – iOS 14+, OSX+, Android 10+, Windows 10) and most recent version of your browser (Chrome, Edge, Firefox or Safari). You must have a front facing camera.
How do I access the evidence?
To access the evidence you will need to submit a request through our “contact us” function. You will be asked to provide the full name and date of birth along with the Death Certificate. We will release a certified copy of the original call evidenced by the unique hash. Where the evidence is required for a court case where proceedings have been issued we will also provide a statutory declaration for the courts. Release of evidence is free where the subscription continued throughout the lifetime of the deceased. We charge an admin fee for release where the subscription was cancelled.
How do I download a Capacity Vault certificate?
You can download your certificate by following the link you see after completing your recording. We will also email you a link you can use. Finally you can log into your account at any time whilst you have a subscription to download any and all of your Capacity Vault certificates.
Can I update my evidence?
Yes – we recommend you make a new call every time you update your will or add a codicil. You should make the call immediately before or after you execute your will. You can make new evidence for free whilst you maintain your subscription.
Can I use Capacity Vault with a dementia related illness?
Yes. If you have a diagnosis of a dementia related illness such as Alzheimer’s you can use our service. Please note that if your will is challenged your recording will be made available for examination. The courts and any expert witnesses will use the evidence you record to check if you had testamentary capacity at the time you made the recording.
Can I use Capacity Vault without a dementia related illness?
Yes. You can use the service if you have no concerns around your testamentary capacity. You may choose to do this if you are worried that someone may challenge your will. A challenge is more likely if you choose to leave a close relative out of your will. By leaving evidence in the form of a Capacity Vault recording the chance of a successful challenge is greatly reduced.
Can I use it if I am at hospital?
You can use Capacity Vault anywhere and at any time. We recommend that you are on your own when you make the call although medical professionals can be present (they will be asked to identify themselves during the call). Please also make the call somewhere without background noise. Hospitals can be noisy places with machines, ward rounds and visitors.
Can I help others use Capacity Vault?
We recommend Capacity Vault calls are made without anyone else present. A solicitor or medical professional can be present. If a family member or friend is present this could lead to accusations of undue influence. This is especially likely if you benefit under the terms of the will.
Can other people help me use it?
You should make the call on your own but a medical professional or solicitor can be present. Anyone present at the time of the call will be asked to identify themselves.
Can I use Capacity Vault in Scotland/ Northern Ireland?
Capacity Vault is designed for use in England and Wales. It follows English and Welsh case law in the questions.
Can I use Capacity Vault outside of the UK?
If you are resident and/ or domiciled outside of England and Wales then we would recommend seeing a local solicitor, advocate or lawyer. Capacity Vault is designed for use in England and Wales.
