Former BBC Radio 2 presenter Colin Berry left his wife £260,000 after he died aged 79 last month.
Berry, who first broke into broadcasting with pirate station Radio Caroline, went on to become a household name on BBC Radio 2.
He continued reading the news on Radio 2 as a freelancer until September 2012 - becoming the station's longest-serving newsreader.
In a will made in 2015, Berry have his entire estate to his trustees - his wife Sandra, or, had she not survived him, his daughter Marina and son Jonathan.
Berry, who lived in Borehamwood, Hertfordshire, directed that his fortune should be handed to his sister-in-law Valerie, if all three had not survived him.
