Aaron Abramowitz said in a statement that Rachelle Spector has been devoted to her husband and has been providing support and care while he is incarcerated.
He wrote: “This whole situation is heartbreakingly bizarre.
“It is regrettable that Mr Spector has failed to recognise the efforts made by Rachelle in spending tens of thousands of dollars on his medical and dental costs while incarcerated.”
Court records in Stockton, California, show Spector filed for divorce on 18 March.
The 75-year-old is at a prison facility in the city which provides medical and mental health care to the state’s most unwell inmates, including those with chronic conditions.
He became known for his Wall of Sound production method and worked with a number of stars in the 1960s to produce pop hits including Da Doo Ron Ron, Be My Baby and the Righteous Brothers’ You’ve Lost That Lovin’ Feeling.
Mr Abramowitz said Rachelle Spector had obtained her pilots’ licence to make it easier for her to visit her husband.
They met at a Hollywood restaurant in 2003, shortly after he was arrested over the shooting death of Lana Clarkson.
Spector was later convicted of killing Ms Clarkson and is serving a sentence of 19 years to life.
The couple married in 2006, and Rachelle Spector has been running her husband’s businesses while he is in prison.
