It’s been more than 16 months since Paul Walker tragically died in a fiery car crash. But since then, his family’s heartbreak has been exacerbated by anguish as they’re forced to deal with their on-going legal issues resolving the details of his estate.

Paul’s father, Paul Walker III, recently opened up about going to court with paperwork claiming the late actor’s business partner Roger Rodas — who was also killed in the Nov. 30, 2013 crash — was still holding nearly $2 million worth of sports cars belonging to the actor at the time of their deaths.

“I don’t know a lot of stuff going on. The trust lawyers do that,” the elder Mr. Walker tells ‘Radar Online.’

“They said there’s been no cooperation, no phone calls returned, nothing.”

The older Mr. Walker insisted he's not inherently blaming Roger’s family for the ongoing problems caused by the messy situation. He said, “It’s not necessarily the Rodas family, but the people who were working for Roger. It could be sloppy paperwork, but no one has cooperated. So at some point [the attorneys] said, ‘We’re going to do this to get their attention.’”

While Paul Sr. is determined to put this issue behind him, he also noted that neither he nor his sons will benefit financially from the sale of the sports cars, telling ‘Radar,’ “It goes all to [Paul’s] daughter.”

He says he’s seen his 16-year-old granddaughter, Meadow, “very, very little” since his son’s death.

For Paul Sr., his son’s death still doesn’t feel “real” — but we doubt it ever will.

“It’s been over a year and I’m still so much in shock,” he has said in the past. “Sometimes I wonder if it’s just been a very long dream… He was taken so suddenly and out of turn.”
