Fact-Checking Michael Gambon’s Estate: Did He Leave His Mistress and Younger Sons out?
Fergus Gambon carried out his duties as sole active executor alongside his mother. In professional circles, Fergus is widely respected for his forensic work on British ceramics, regularly evaluating rare heirlooms on BBC’s Antiques Roadshow.
The decision to funnel the entire formal estate to Lady Anne makes profound financial sense under the UK Inheritance Tax (IHT) framework. Under Section 18 of the Inheritance Tax Act 1984, transfers between legally married spouses are 100% exempt from inheritance tax.
By passing the £1,465,882 estate entirely to Lady Anne, the estate incurred a 0% tax liability. If Gambon had distributed that sum to Hart, with whom he was not legally married, the estate would have faced a punitive 40% inheritance tax bill on every pound above the standard nil-rate band. The spousal transfer kept the entirety of his probated fortune intact for the family.
