1. Why Wills Are Contested

Most challenges fall into one of four categories:

GroundWhat It MeansTypical Evidence Required
Lack of CapacityThe testator didn’t fully understand their actions when the will was signed.Medical records, witness statements, solicitor notes.
Undue InfluenceSomeone pressured or coerced the testator into changing the will.Emails, texts, sudden will changes, testimony from friends or carers.
Lack of Proper FormalityThe will wasn’t signed or witnessed in line with the Wills Act 1837.Examination of signatures, witness availability.
Fraud / ForgeryThe signature or content was faked, altered or concealed.Handwriting experts, digital forensics.

A separate route—the Inheritance (Provision for Family and Dependants) Act 1975—lets certain relatives or dependants claim reasonable financial provision even if the will itself is valid.



2. Deadlines at a Glance

Type of ClaimDeadlineCan It Proceed After Probate?

Tip: Even where no hard deadline exists, delay weakens evidence. Speak to our Probate team as soon as concerns arise.


3. How the Process Works

  1. Pre‑action investigations
    • Request a copy of the will & probate papers.
    • Gather medical notes, solicitor file, witness details.
  2. Enter a Caveat (optional)
    Prevents probate for 6 months while you investigate.
  3. Send a ‘Larke v Nugus’ letter
    Asks the will‑writer for full background and execution notes.
  4. Attempt mediation
    Courts expect parties to try settling early.
  5. Issue court proceedings
    If no agreement, your solicitor files a claim in the Chancery Division.
  6. Disclosure, witness evidence & expert reports
    Handwriting experts, doctors, financial analysts may be involved.
  7. Trial or settlement
    Most disputes resolve before trial—but solid preparation is vital.
