Simply put, a Will is a legal document which contains a person’s intentions as to how they wish to distribute their assets after they pass on.
The legal definition of a Will is covered in Section 2 of the Wills Act 1959:
“…a declaration intended to have legal effect of the intentions of a testator with respect to his property or other matters which he desires to be carried into effect after his death and includes a testament, a codicil and an appointment by will or by writing in the nature of a will in exercise of a power and also a disposition by will or testament of the guardianship, custody and tuition of any child.”
