divorce & entitlement per ex father in-law's will

[Skidder]

In Ontario Canada, does Sharon have to be married to William at the time of William's death to be entitled as a beneficiary when in his father's will it states "On the death of my said son, the sum of $(amount) of the capital so invested shall be paid over to (a charity) and the remainder of the capital sum together with all undistributed interest, shall be kept invested, and the net income therefrom shall be paid to SHARON, the wife of the said William, for and during the remainder of her lifetime, and on her death .....(their daughter inherits)". Thanks

Not unless the Will specifically states she must be married to him. Otherwise, she's a beneficiary whether she's married to William or not.
