Inside Michael Gambon’s Double Life: Why Mistress Philippa Hart Was Left out of His Will

An in-depth perspective on Inside Michael Gambon’s Double Life: Why Mistress Philippa Hart Was Left out of His Will, highlighting expert commentary.

Estate planning attorneys in London were quick to point out that a will subject to public probate represents only a slice of a high-net-worth individual's genuine wealth transfer. English probate filings capture only assets held solely in the deceased’s personal name at the time of death.

Several financial mechanisms explain why Philippa Hart was not included in the will:

First, property ownership structures frequently bypass probate entirely. If the West London home where Hart lives with Tom and Will was purchased under a joint tenancy with right of survivorship, ownership would have transferred to Hart immediately upon Gambon’s death without appearing in court filings. The same applies if the property was held in Hart’s name alone or placed inside an irrevocable lifetime family trust.

Second, the recorded net figure of £1,465,882 is surprisingly low for an actor who starred in four Harry Potter blockbusters and worked continuously on television for half a century. Substantial earnings over his late-career renaissance were likely channeled into private pension schemes, corporate entities, or educational trusts designated for his younger sons. These arrangements operate outside public wills, keeping transfers shielded from prying eyes.

Finally, there is the issue of inheritance tax. In the UK, transfers between legal spouses are 100% exempt from inheritance tax under the spousal exemption rule. Leaving £1.47 million to Hart would have incurred an immediate 40% tax charge on everything over the standard nil-rate threshold. Leaving the balance to his legal wife allowed the entire estate to transfer tax-free.
