How Social Media Can Harm or Help Your Claim

Social media evidence is now a routine feature of probate disputes in England and Wales. Because so many people document their lives, relationships, frustrations, and intentions online, platforms such as Facebook, Instagram, WhatsApp, X (Twitter), and TikTok increasingly provide material that can strengthen or undermine a party’s position. When a will is challenged, whether for lack of capacity, undue influence, want of knowledge and approval, or fraudulent calumny – social media may become strong indicators of what the deceased truly intended, how they behaved, and what pressures they may have faced.

How social media evidence fits into probate disputes

Courts in England and Wales treat social media content as a form of documentary evidence. Posts, messages, photos, videos, and even “likes” or comments can be admissible if they are relevant and properly authenticated. However, because probate disputes often hinge on the deceased’s state of mind, relationships, and intentions, social media can potentially provide insight that traditional evidence sometimes lacks.

Key areas where social media evidence is commonly used can include:

• Capacity disputes – Posts or messages may show confusion, memory lapses, or inconsistent behaviour around the time a will was made.
• Undue influence claims – Online interactions can reveal controlling behaviour, isolation of the deceased, or sudden changes in relationships.
• Knowledge and approval challenges – Social media may show whether the deceased understood their decisions or discussed their wishes with others.
• Fraudulent calumny – Messages or posts spreading false allegations about another beneficiary can be powerful evidence of manipulation.
• Executor or beneficiary conduct – Online statements can undermine credibility or reveal hidden motives.

Because social media captures real-time behaviour, it may even sometimes carry more weight than retrospective witness statements.

How social media evidence can help a probate claim

It provides important insight

Courts value evidence created at or near the time of the disputed events. A WhatsApp message sent the day a will was signed may be more persuasive than a witness recalling events years later.

It reveals genuine relationships

If someone claims to have been very close to the deceased, but their social media shows little or no interaction, that inconsistency can be important. Conversely, posts showing affection, support, or involvement can strengthen a claim.

It highlights patterns of behaviour

Courts look for repeated signs of pressure, manipulation, confusion, or isolation. A series of messages or posts can paint a clearer picture than a single comment.

It can expose dishonesty

If a beneficiary says one thing in court but their social media tells a different story, their credibility may be damaged. 

And when social media can harm your probate claim

Posts may contradict your version of events

If you claim you were estranged from the deceased, but your social media shows regular contact, the court may doubt your evidence.

Deleted content can raise suspicion

Removing posts or messages after a dispute begins can be seen as an attempt to hide evidence. Courts can draw negative conclusions from this.

Online arguments can undermine your position

Angry posts about family members or the deceased can weaken claims of a close or harmonious relationship.

Financial or emotional motives may be revealed

Posts about money worries, inheritance expectations, or resentment can be used to challenge your intentions.

Example 1: Social media supporting an undue influence claim

A man leaves his entire estate to a new partner, cutting out his adult children. The children believe the partner pressured him into changing his will.

Social media strengthens their case:

• The partner’s posts show repeated criticism of the children and comments about “getting what I deserve.”
• WhatsApp messages reveal the partner telling the man to stop speaking to his family.
• The man’s own posts show he suddenly withdrew from long-standing friendships after the relationship began.

This pattern supports the argument that the partner isolated and influenced him, making the will vulnerable to challenge.

Example 2: Social media undermining a claim of manipulation

A son argues that his sister poisoned their mother’s mind with lies, causing the mother to exclude him from her will.

Social media weakens his claim:

• The mother’s private messages show she had concerns about the son’s behaviour long before the will was changed.
• The son’s own posts show he joked about borrowing money from his mother without repaying it.
• The sister’s social media shows she encouraged family contact rather than discouraging it.

The court concludes the mother made her own decisions, and the claim fails.

What courts look for when assessing social media evidence

Authenticity

Courts prefer evidence that can be verified. Screenshots may be accepted, but metadata or platform downloads are stronger.

Relevance

The content must relate to the issues in dispute. For example capacity, undue influence, knowledge and approval, or fraudulent calumny.

Context

A single message can be misleading. Courts look at the wider pattern of communication.

Preservation

Once a dispute is likely, parties must not delete or alter content. In fact, doing so can harm their case.

Reliability

Courts consider whether the account genuinely belonged to the deceased or another party, and who was posting the content. 

How solicitors use social media in contentious probate cases

Specialist probate solicitors may often:

• Review publicly available posts to understand relationships
• Request disclosure of private messages through formal legal processes
• Use digital forensic experts to recover deleted content
• Analyse communication patterns to support or challenge claims
• Prepare cross-examination based on inconsistencies between online behaviour and court statements

Because social media is so personal, it often reveals information that traditional evidence does not.

Why social media evidence is becoming more common

Three major trends explain its growing importance:

• Most people now communicate digitally rather than in writing or face-to-face.
• Courts increasingly recognise that online behaviour reflects real life.
• Probate disputes are rising, especially in blended families and high-value estates, making every piece of evidence more significant.

As a result, social media is no longer a side issue. It can be central to proving or defending a claim.

Key social media takeaways for anyone involved in a probate dispute

• Social media can help or harm your case depending on what it shows.
• Courts treat online content as legitimate evidence if it is relevant and authentic.
• Posts, messages, and interactions can reveal relationships, intentions, and behaviour patterns.
• Deleting or altering content after a dispute arises can damage your credibility.
• A solicitor experienced in contentious probate can help identify what evidence is useful and how to present it effectively.
