Overview of all answers.

Name the mistake concretely

Mistake in a will: false assumptions and challenge requires a structured assessment rather than assumptions. The contractual, testamentary or probate documents must be read together with the factual history.

Organise evidence outside the document

Evidence decides the practical strength of the position. Documents, timelines, correspondence and payment flows should be collected before conclusions are drawn.

Disappointment is not automatically challenge

The strategy should remain case-specific. A claim may call for information, negotiation, preservation of evidence or court action depending on the risk.
