Ex-Wife Convicted of Blackmail After False Allegations Threatened Dentist’s Career
By Michael Thompson, Founder, Falsely Accused Network | 14 October 2026
A dentist endured nine months of uncertainty after his former wife made false allegations that he had been drinking alcohol while treating patients, in an attempt to pressure him into paying her more money following their divorce.
Dina Williamson, 39, pleaded guilty to blackmail at Bournemouth Crown Court after threatening to report her former husband, Ben Williamson, to the General Dental Council (GDC). When he refused to respond to her demands, she carried out her threat.
The case shows how malicious allegations can be used to exert financial pressure and to threaten a person's professional reputation, career and livelihood.
From Divorce Dispute to Criminal Proceedings
According to reporting of the hearing at Bournemouth Crown Court, the couple met in 2019, married in 2022 and divorced in 2024.
In March 2025, Dina Williamson began raising the possibility of reporting her former husband to the GDC. By April, Mr Williamson had made clear that he did not wish to communicate with her directly and asked that any further correspondence go through his solicitors.
The situation escalated the following month. The prosecution told the court that she sent messages describing financial difficulties, including problems paying rent and reliance on food banks, and threatened to report him to his professional regulator unless he provided further financial help.
When he did not respond, she submitted allegations to the GDC claiming that he was an alcoholic in recovery who had been drinking between treating patients. She also reportedly posted comments on his dental practice's Facebook page suggesting that some male dental surgeons were unfaithful to their wives.
Nine Months Under Investigation
The GDC was required to consider the allegations. For a dental professional, a claim of drinking alcohol between patients is potentially extremely serious: it goes directly to patient safety, fitness to practise and, ultimately, registration.
Mr Williamson, who had practised dentistry for 16 years, faced a nine-month investigation. The GDC concluded its investigation in February 2026 and took no further action.
In his victim impact statement, Mr Williamson described the distress caused by the prospect of fitness-to-practise proceedings and the threat to his career, which he said had compounded an already painful divorce. The court heard that the allegations were false and had been made maliciously.
Judge Condemns Malicious Conduct
Dina Williamson pleaded guilty to one count of blackmail. Sentencing her, Judge Jonathan Fuller concluded that she had tried to damage her former husband's professional reputation because she felt unfairly treated by their divorce settlement. He described the allegations as salacious and vexatious. As reported, he told her:
“You sought to undermine and damage his professional reputation.”
She received a three-month prison sentence, suspended for 12 months, and therefore avoided immediate custody.
What the Law Says
Blackmail is an offence under section 21 of the Theft Act 1968. It is committed where a person, with a view to gain for themselves or another, or with intent to cause loss to another, makes an unwarranted demand with menaces. The maximum sentence on indictment is 14 years' imprisonment.
Two points are worth noting. First, the offence is complete when the demand is made: it does not depend on the threat being carried out or on any money being paid. Second, the offence turns on the demand and the menaces, not on whether the threatened allegation is true. In this case, the court was also told that the allegations were false, which added to the harm Mr Williamson described.
False Allegations Can Have Serious Consequences
At the Falsely Accused Network, we recognise that people can face allegations they believe to be false following the breakdown of a relationship. Such allegations can arise in criminal investigations, family court proceedings, employment disputes and complaints to professional regulators.
The consequences can extend well beyond the original allegation: months of uncertainty, substantial legal costs, reputational damage, emotional distress and threats to employment. Mr Williamson was ultimately cleared by his regulator, but the investigation still ran for nine months. Being cleared does not necessarily undo the consequences of having been accused.
The Misuse of Complaints Procedures
Professional regulators, police forces, employers and safeguarding bodies must take genuine allegations seriously. That responsibility is essential to protecting the public and ensuring accountability.
However, the Williamson case illustrates how complaints procedures can also be deliberately misused. By her guilty plea, Dina Williamson admitted using the threat of a regulatory complaint in an attempt to obtain money.
This distinction matters. A complaint that cannot be substantiated is not automatically false or malicious; many genuine concerns cannot ultimately be proved. But where the evidence establishes that allegations were deliberately fabricated to threaten, punish or financially exploit someone, there must be appropriate accountability. Here, the criminal justice system responded with a conviction for blackmail.
What Can Someone Do If They Are Targeted?
If you believe false allegations are being used to threaten your career, reputation or finances, practical steps may include:
Preserving all communications, including messages, emails and social media posts, with dates and screenshots.
Keeping a written record of each threat or demand as it happens.
Avoiding direct confrontation and, where possible, routing contact through a solicitor.
Taking advice from a solicitor experienced in regulatory proceedings if a professional regulator is involved.
Considering a report to the police where threats are linked to demands for money.
Every case is different, and the right response depends on the evidence and the circumstances.
Fairness Must Work Both Ways
The Falsely Accused Network supports the right of genuine victims to report abuse and misconduct and to have their concerns properly investigated. We equally believe that anyone facing allegations is entitled to fair procedures, impartial consideration of the evidence and, in criminal proceedings, the presumption of innocence. These principles should work together.
A person's professional reputation should never become a weapon in a personal or financial dispute.
