A will written in one's own hand is a self-written will.

Paragraph 2 of Article 17 of my country's "Succession Law" stipulates: A self-written will shall be written and signed by the testator, and the year, month and day shall be indicated.

A self-written will does not require the presence of witnesses to be legally effective, but a self-written will should meet the following formal requirements: 1. The testator writes the contents of the will.

The testator should write the full text of the will in person, which can not only truly express the testator's will, but also prevent others from forging, tampering with, or adding to the will.

2. The testator shall indicate the year, month, day and place of writing in the will written by himself.

The time when a will is made has a certain impact on the validity of the will. If the contents of different written wills conflict, the later written will shall prevail.

At the same time, the time when the will was made can sometimes prove the authenticity of the contents of the will.

3. The testator’s signature.

4. If there are any alterations, additions or deletions in a self-written will, the number of words that have been altered, added or deleted should be noted next to the alterations, additions or deletions, and a separate signature should be placed at the places where the alterations, additions and deletions are made.

The Judicial Interpretation of the Supreme People's Court stipulates: "If the content of a citizen's suicide note concerning the disposition of personal property after death is indeed the true expression of the deceased's intention, signed by someone and marked with the year, month, and day, and there is no evidence to the contrary, the suicide note may be regarded as self-written.

"In addition, in order for a self-written will to be effective, it must meet the substantive requirements stipulated by law: 1. The testator must have testamentary capacity. Testamentary capacity refers to the ability of a natural person to establish a will and freely dispose of his property in accordance with the law.

.

A will is a civil act, and the author must have corresponding civil capacity.

According to the current laws of our country, only persons with full capacity for civil conduct have the capacity to establish a will, that is, testamentary capacity. People who do not have full capacity for civil conduct do not have testamentary capacity.

Therefore, the testator must be a person with full civil capacity.

According to Article 22 of my country’s Succession Law, a will made by a person without capacity or with limited capacity is invalid.

Whether the testator has testamentary capacity shall be determined at the time when the will is created.

If the testator has testamentary capacity when creating a will, even if he subsequently loses testamentary capacity, the will will not lose its validity.

vice versa.

Therefore, the Supreme People's Court clearly stipulates in Article 41 of the "Opinions on Several Issues Concerning the Implementation of the Succession Law of the People's Republic of China": "The testator must have the capacity to act when making a will.

Even if the testator later becomes capable of acting, it will still be invalid. If the testator was capable of acting when he made the will, but later loses it, the validity of the will will not be affected. "2. The will must be the true will of the testator.

It must be the true expression of intention of the testator to dispose of his property, because true expression of intention is a necessary condition for the validity of a civil act.

Whether a will is the testator’s true expression of intention shall, in principle, be based on the last expression of intention made by the testator in the will.

A will made under duress or deception is invalid; a forged will is invalid; and if a will is tampered with, the tampered content is invalid.

3. The will shall not cancel the inheritance rights of heirs who lack the ability to work and have no source of income. Article 19 of my country's "Succession Law" stipulates that the will shall reserve the necessary share of the inheritance for the heir who lacks the ability to work and has no source of income.

This provision is mandatory. A will that cancels the inheritance rights of an heir who lacks the ability to work and has no source of income will not be valid.

If the testator does not retain the share of the estate of an heir who lacks the ability to work and has no source of livelihood, when the estate is disposed of, the necessary inheritance should be left for the heir, and the remaining portion can be handled with reference to the distribution principles determined by the will.

Whether an heir lacks the ability to work and has no source of income should be determined based on the specific situation of the heir when the will takes effect.

4. The property disposed of in the will must be the testator’s personal property. Since the will is a civil act for the testator to dispose of his personal property, it can only dispose of the testator’s personal legal property.

If a testator disposes of property owned by the state, a collective or others in a will, that part of the will shall be deemed invalid.

5. The will must not violate public interests and social ethics. Civil acts that violate public interests and social ethics are invalid.

A will will not be valid if it harms the interests of the public or if its content violates social ethics.

When there are several wills, the laws of our country are as follows: Article 42 of the "Opinions of the Supreme People's Court on Several Issues Concerning the Implementation of the Succession Law of the People's Republic of China" stipulates: The testator has made several wills in different forms with conflicting contents.

If there is a notarized will, the last notarized will shall prevail; if there is no notarized will, the last will shall prevail.

To sum up: in order for a handwritten will (self-written will) to be effective, it must comply with the formal and substantive requirements stipulated by the law, and there must be no conflicting will.

If there is a conflicting will, the conflicting will cannot be a notarized will, and the self-written will is the last will made.
