A will may be contested on the basis that the will maker did not intend the document in question to be their last will and testament. Normally wills can only be contested on the basis that they are invalid because...

  1. The will maker made a later will
  2. The will maker did not have the mental capacity to make a will
  3. The will maker's signature was forged or parts of the will were changed after it was signed
  4. The will maker was tricked or pressured into signing the will
  5. Or the will was revoked.

In any such cases it is necessary for the person contesting the will to have sufficient evidence in a form acceptable by the Court, and sufficient to persuade the Court to make relevant orders.
