With regard to making a will, a citizen may make a will to dispose of his personal property, and may appoint a testamentary executor to designate one or more legal successors to inherit his personal property, or may make a will to donate his personal property to the state, a collective or a person other than the legal heir. And the effect of testamentary succession is higher than statutory succession. Therefore, when the decedent makes a will, he should dispose of his personal property according to the will.
 According to the law, testamentary succession can be divided into notarial testament, self written testament, written testament, recorded testament and oral testament, among which written testament, recorded testament and oral testament must have more than two witnesses who have no interest; At the same time, in all testamentary succession, the notarized will has the highest effect.
 Therefore, a will is a legal form of disposition of citizens' property before their death, and no one can interfere with it. A person may designate an heir to the property by making a will, excluding the spouse's right of inheritance. However, the estate needs to be clear and comply with the relevant legal provisions of the testament.
