Can I write my own will and register it?

Yes, you can write your own will in the UK, as long as it meets the legal requirements under the Wills Act 1837. This includes being in writing, signed by you, and witnessed by two independent adults. While registering your will is optional, you can store it with the National Will Register for a small fee to ensure it can be found after your death. However, self-written wills carry a higher risk of errors, so professional legal advice is recommended to avoid disputes and ensure your will is valid.
