This sets out the legal grounds, capacity, undue influence, an Inheritance Act claim, and weighs your prospects against the cost and the family fallout. For anyone deciding whether to take this on before spending a penny.

**Evaluate whether contesting the will is worth pursuing:**
1. What legal grounds exist (lack of capacity, undue influence, lack of knowledge and approval, Inheritance Act 1975 claim)?
2. Based on the situation described, which ground, if any, appears strongest?
3. What evidence would be needed to support a claim?
4. What are the realistic costs, timescales, and prospects of success?
5. What are the relational and emotional costs of pursuing a contested probate case?
