BBC antiques expert David Harper, 52, paid £15,000 a year for daughter Hetti to attend Barnard Castle School, where she has been educated since the age of five.
After finishing school, 23-year-old Hetti formed a band and decided to get a tattoo - opting for the slightly unusual choice of her school's slogan tattooed across her chest.
David, an antiques expert and star of the BBC's Antiques Road Trip, is now calling for the school to return the money he spent on Hetti's tuition fees, on the basis that her tattoo constitutes free advertising for the boarding school.
Hetti got the tattoo - which reads 'Parvis imbutus tentabis grandia tutus' - three weeks ago, honouring the slogan of the school in Barnard Castle, County Durham.
She said she's already being stopped in the streets by people curious to know the translation, which is: 'When you are steeped in little things, you shall safely attempt great things'.
However, her dad hasn't been quite so impressed, and said he 'freaked out' when he first saw her new ink.
David, from Durham, said: "I've asked if Barnard Castle School would be happy to refund some of the school fee's I paid, because my daughter has tattooed the old school motto across her chest.
"It was just a bit of a shock to me and her mother!
"After I freaked out at the sight of the tattoo, I was furious that after all the money I'd spent on her education, I really didn't expect her to end up being a free walking advert for the school.
"However, a little later I had the brilliant idea to ask the school if they'd effectively like to sponsor Hetti in her music career and give me back some of the school fees I'd paid."
Hetti has been at Barnard Castle School since she was five, having moved up to the main school at 11 where she was classically trained as a singer.
She became head of their choir before she left school at the age of 18, going on to form her own band, Tiffany Twisted.
David added: "Hetti moved to London three years ago and has been writing and composing music for the past two years.
"Hetti thought it a great idea to have the school motto tattooed across her torso, as the school played such a big part in her music development - never mind who paid the school for this!
"I'm hoping that I'll get some money back from the school and from Hetti once she makes it."
Tiffany Twisted will be releasing their debut track 'Holes In Your Bones' on 20 August through Payne Records.
(There you go, now there's some free advertising for her band as well as the school. Bravo, everyone.)
