In doubtful cases, there is no presumption in favor of the will.

Explanation

A testamentary instrument clouded by ambiguity is not presumed to speak — the burden falls on the proponent to demonstrate intent.

Where this applies

• A will is ambiguous and they're claiming a presumption in the will's favor.
• A doubtful testamentary instrument doesn't get the benefit of a presumption.
• The person pushing the will has to prove its meaning — there's no automatic presumption in their favor.
