The Kent church is also where the 25-year-old television presenter, model and socialite married musician Tom Cohen, the father of her children, in 2012.
And it is also where television presenter Yates, who died from an accidental heroin overdose in 2000, aged 41, married Bob Geldof in 1986.
Her family says the event will be private. She died on April 7, leaving two young sons, Astala, 23 months, and 11-month-old Phaedra.
Kent Police said her death is being treated as a “non-suspicious, unexplained sudden death”.
