The “Mr. Bean” star has been estranged from ex-BBC make-up artist Sunetra, 54, since the couple split in 2014.
Atkinson and his wife were granted a decree nisi by a District Judge at the Central Family Court in a short hearing lasting less than a minute.
Neither he nor Sunetra, who lodged the petition, were present in court for the announcement, reports dailymail.co.uk.
A source earlier told The Sun: “Sunetra was deeply upset to be replaced by such a younger woman.”
Atkinson, 60, has been dating 32-year-old Louise Ford for 18 months. She has appeared in Channel 4’s Misfits and starred alongside “Inbetweeners” actors Simon Bird and Joe Thomas in Sky’s “Chickens”.
