Under Kansas law, tattoo artists are only allowed to carry out ink work in licenced facilities, ruling out any work being done on the prison premises.
Barton County Police have already stated that they would not be willing to transport Chapman to a licenced studio.
"The fact that he has 'murder' tattooed across his neck is irrelevant to the State's case and extremely prejudicial to Mr Chapman if introduced at trial or observed by the jury," said Kurt Kerns, Chapman's defence attorney.
"Mr Chapman asks for the court to exclude any mention of his tattoos at trial and further to be allowed to cover them up in an appropriate manner."
It is not the only tattoo on Chapman. Inked beneath his right eye is a black teardrop.
It has not been revealed the background of Chapman's tattoos or why he decided to get them done in the first place.
Chapman has been charged with the shooting of Damon Galyardt who was found dead in a roadside ditch in November 2011.
