When a Will Does Not Look Right: Grounds to Challenge It

A will that was changed late in life, under pressure, or when the person was not themselves, can sometimes be challenged. But suspicion alone is not enough.

Published 24 October 2026 · Last verified 24 October 2026 against Ontario estates law · By the Yu Sheng Wills & Estates Team

The main grounds

A will can be challenged on several grounds, that the person lacked the mental capacity to make it, that they were unduly influenced or pressured, that they did not know and approve of its contents, or that it was not properly signed and witnessed. Each is a distinct legal test with its own evidence.

Suspicion is not proof

Families often feel a will is unfair, but unfairness is not a ground to set it aside. A successful challenge needs evidence, medical records, the circumstances in which the will was made, the role of those who benefited. These cases are fact-intensive and often emotionally charged.

Will challenges are among the most painful and expensive disputes a family can have. Whether you are considering a challenge or defending a will, an early and honest assessment of the real strength of the case, before positions harden, saves enormous cost and heartache.

Act within time

There are limitation periods and practical deadlines, and evidence fades quickly after a death. If something about a will does not look right, the time to get advice is early, not after the estate has been distributed.

当一份遗嘱“看起来不对劲”:可以挑战的理由

一份在人生晚期被更改、在压力下作出、或当事人“已非本人”时所立的遗嘱,有时可以被挑战。但仅凭怀疑并不够。

主要理由

遗嘱可基于若干理由被挑战:立遗嘱人欠缺立遗嘱的心智能力;受到不当影响或胁迫;不知悉且未认可其内容;或签署与见证不合规。每一条都是独立的法律要件,各有其证据要求。

怀疑不等于证明

家属常觉得一份遗嘱“不公平”,但不公平本身并不是撤销它的理由。一次成功的挑战需要证据:医疗记录、遗嘱作出时的情形、受益之人所扮演的角色。这类案件高度依赖事实,且往往情绪激烈。

遗嘱挑战是一个家庭可能经历的最痛苦、最昂贵的争议之一。无论你是在考虑挑战、还是在捍卫一份遗嘱,在立场僵化之前,对案件真实强弱作一次尽早而坦诚的评估,能省下巨大的成本与伤痛。

在时限内行动

存在时效期间与现实的时间节点,而证据在人去世后会迅速消散。如果一份遗嘱让你觉得哪里不对,获取意见的时机是尽早,而不是在遗产已分配之后。
