A Will or testament is a legal document by which a person, the testator, expresses their wishes as to how their property is to be distributed at death, and names one or more persons, the executor, to manage the estate until its final distribution. If you die without making a Will, then the government will decide who gets what. If you don't have any family members, all your assets will go to the Crown. Contact a lawyer to make your wishes come true by leaving your wealth to the right person or charities.
