Who is qualified to contest a will?

To contest a will, you must be an “interested person” – a person who stands to gain or lose from the way the deceased person’s estate is distributed. An interested person might be an heir, devisee, spouse or even a creditor. The “interest” does not even have to be financial – it can include, for example, an interest in the welfare of an incapacitated person whose guardianship is provided for in the will.
