Legal analysis: if an heir forges a will in order to obtain an inheritance, if the circumstances are serious, it can be considered as loss of inheritance.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 125 An heir who commits one of the following acts shall lose the right of inheritance:

(1) Intentionally killing the decedent;

(2) Killing other heirs in order to compete for the right of inheritance;

(3) Abandoning the decedent or maltreating the decedent if the circumstances are serious;

(4) Forging, tampering, concealing or destroying a will, if the circumstances are serious;

(5) forcing or obstructing the decedent to establish, change or withdraw his will by means of fraud or coercion, and the circumstances are serious.

If the heir has committed the acts mentioned in Items 3 to 5 of the preceding paragraph, and indeed shows repentance, and the decedent later expresses forgiveness or is listed as an heir in his will, the heir shall not lose his inheritance right.

If the legatee commits the act specified in the first paragraph of this article, he shall lose the right to be bequeathed.

Article 148 An estate administrator shall perform his duties according to law, and shall bear civil liability if he intentionally or negligently causes damage to his heirs, legatees and creditors.
