The Courts Service has apologised for sending jury summonses to the deceased.
In a statement to Deise Today on WLR, the Courts Service said jury summonses were issued randomly from the databases of electoral registers in each constituency.
When a person dies they remain on the register until the local council is informed.
The programme had been contacted earlier in the week by an elderly listener who is still receiving letters addressed to his late wife despite passed away earlier this year.
The issue brought on a flurry of calls and texts from listeners who are still receiving letters for their late relatives.
Anne, who texted the show, said she contacted the council after both her parents had died, only for it to take three years to get them taken off the register: "I filled out a form in the office and was assured that they both would be removed. At the last election I received a voting card for my mother. It was so upsetting. I also received medical cards for both of them after I called to the office handed back their medical cards. It was so distressing and upsetting."
Helen's daughter Caroline died 9 years ago when she was 21, and said that it was distressing to still be receiving post for her.
"We got in touch with the court service and we told them that she had died, they said they were very sorry and very apologetic [but] we're still getting voting cards," she told presenter Damien Tiernan.
James Cusack's uncle died almost ten years ago - he too has been called for jury service: "I sent them an email to say that was he was deceased. It's not good enough and I think that when a death certificate is issued that should trigger a lot more things along the line."
A spokesperson for the Courts Service said it "appreciates that it is a cause of discomfort" for family members.
"All services the deceased was registered for need to be unregistered by the survivors. We are conscious of this and of the difficult time people go through as they put a person's affairs in order, maybe dealing with the granting of probate for a will, or un-registering the deceased - their loved one - from many other services and lists.
"When informed of a death and having received a death cert, we routinely place a code beside that name so as no future summons is produced by the computer system. This ensures no future summons is issued."
The spokesperson added that due to CVoid-19 restrictions on numbers gathering, it has automated replies to letters received looking to be excluded from jury service.
They said: "When we have sufficient numbers for to empanel a jury, and so as to limit the numbers in attendance, the system automatically lets those who are not now needed, that they are excused by the County Registrar. Unfortunately, this also included those who wrote to inform us of the details of the deceased. It was a flaw in our approach, for which the Courts Service offers its sincerest apology."
The Courts Service said it is working to remedy this situation and to respond in "a more personal and individual way" to those who inform it of deceased people receiving summonses.
