What are common grounds for contesting a will in Ontario?

The correct answer emphasizes several critical grounds for contesting a will in Ontario, with a focus on legal and testamentary principles. Testamentary capacity refers to the testator's ability to understand the nature of making a will and the implications of their decisions. If someone lacked the requisite mental capacity at the time of making the will, this could invalidate the document.

Improper execution involves failing to follow the legal formalities required for a will to be valid, such as signing in the presence of witnesses or having the requisite number of witnesses present. If these protocols are not adhered to, the validity of the will can be challenged.

Undue influence pertains to situations where the testator was coerced or manipulated by another party into creating or altering a will in a way that reflects the influencer's desires rather than the true wishes of the testator. This can significantly affect the intention behind the will.

Fraud is a serious allegation where the will itself may have been created or modified through deceit, whether by the testator or by another party seeking to benefit improperly. This can include forgery or misrepresentation regarding the contents of the will.
