If you feel that the will was somehow incorrect or invalid, it can be legally challenged. Reasons to challenge a will include:
1 – Capacity – if the person was too unwell to sign their will.
2 – Undue influence – it the person was unfairly influenced when writing their will, or pressured into writing something that was against their wishes.
3 – Professional negligence – you may feel that the will was written incorrectly by the will writer. If a will is incorrect or badly written, this can also be challenged.
