Grounds for Contesting a Will

Overview

A will can only be contested on recognised legal grounds. In practice, the most common grounds include lack of proper execution, lack of testamentary capacity, lack of knowledge and approval, and allegations of undue influence or fraud. Understanding those distinctions is important because different grounds require different evidence and different legal analysis. Alstern Solicitors can help identify which route, if any, is realistically available in a particular case.

Eligibility / Key Legal Requirements

Key legal requirements:

  • A challenge must be based on a recognised legal ground
  • The grounds relied on should be pleaded clearly and specifically
  • Allegations of capacity, undue influence or fraud require factual particulars
  • The relevant evidence depends on the ground being advanced
  • Delay can make the evidential position more difficult
  • Early assessment is important before proceedings are issued

Common supporting documents:

  • The signed will and any earlier wills
  • Attestation clause and execution evidence
  • Solicitor file and attendance notes
  • Medical records
  • Witness statements
  • Handwritten instructions or notes
  • Correspondence relating to the estate

The above information is intended for general guidance only. Every matter involves different legal and factual considerations. Supporting evidence and legal documentation should be carefully prepared to reflect your individual circumstances. Contact Alstern Solicitors for tailored legal advice specific to your situation.

Common Risks or Mistakes

A common mistake is assuming one suspicion fits every case.

For example:

  • a concern about memory may point to capacity evidence;
  • a concern about pressure may point to undue influence;
  • a concern about paperwork may raise due execution;
  • a concern about whether the deceased understood the will may raise knowledge and approval.

Using the wrong ground can weaken an otherwise legitimate concern.

Case Study from Alstern Solicitors

Background

A family member believed a new will was suspicious because it differed sharply from earlier arrangements.

Challenge

It was not clear whether the issue was capacity, pressure, or whether the deceased fully understood the new document.

How We Assisted the Client

We analysed the factual background, identified the possible legal grounds separately, and advised on what evidence would be needed for each.

Outcome

The client was able to approach the dispute more strategically and avoid making unsupported allegations.

What Happens If You Choose the Wrong or Inexperienced Solicitor?

If the wrong legal ground is chosen, the dispute can become more expensive and less effective.

That can lead to:

  • inadequate pleadings;
  • evidence being gathered for the wrong issue;
  • avoidable procedural problems;
  • loss of negotiating strength;
  • higher costs and delay.
