Yes Kassee that is correct.
Everyone should make a will and a surprising number of people do not, when Robert Holmes a Court died suddenly at the age of only 53 with a £330 million estate he was found to have carried a draft will for 18 months but had never signed it.
If you die without a will your estate may not be distributed in the way you would wish, even people who do not think they own enough to make a will should do so, the leaving of anything can bring out the worst (and best) in families.
Make sure your will is also clear there is the famous case of the testator who said “ All for Mother” the problem was he also called his wife mother, so who was to benefit the wife or mother?
If a beneficiary signs as a witness the will is still valid but the witness will not be able to benefit from the will.
To make a will the person must have mental capacity and be of the age of majority.
A Lasting Power of Attorney, which replaced the Enduring Power Of Attorney, must be registered with the Office of Public Guardian before it is used and there is a fee for registration.
I would suggest a Solicitor should prepare both a will and lasting power of attorney, but it is of course up you you.
