Some people wonder if it is legal to have a handwritten will in the United Kingdom, and the answer is yes. Technically, any piece of paper will suffice as long as your will is signed in the presence of two witnesses who are not beneficiaries in the will.
Consider that if you want your final wishes to be taken seriously, you can write your Will using a predetermined online will form – a scribbled piece of paper might not stand up to scrutiny if your Will is challenged.
