Bill Bellamy 'Devastated' by Family Feud Over Father's Memorial Servi

2:58 PM PT -- 6/29 -- Karen Bellamy has a much different version of how this family dispute got started. She tells TMZ ... "Bill and his wife Kristen demanded that the entire family and loved ones grieve on their schedules. The memorial was never on the same date. The only service that took place is for [their father] William Bellamy, Sr. on June 24, 2022."

She adds, "Bill and his wife made a personal choice to not attend. Kristen’s service for her dad is on June 30, 2022. New Jersey Superior Court denied their request to stop the service."

We contacted Bill's reps and they tell us Bill stands by his original remarks, and won't be commenting further.

Bill Bellamy says he's being forced to make an impossible choice after the deaths of his father and father-in-law -- due to an "unauthorized" memorial service planned by his sister.

The comedian and actor's going through an incredibly painful period ... with his father-in-law dying May 17, and then his own dad passing on June 8.

That would be gut-wrenching enough, but TMZ has learned things got even worse. While Bill was out of the country ... we're told his sister, Karen, made plans to lay their father, William, to rest today, June 24 -- the same weekend Bill and his wife had already planned his father-in-law's service in a different state.

According to documents filed in New Jersey, Bill actually attempted to get a restraining order which would force Karen to change the date, but he was denied -- there really is no legal standing for a judge to get involved in this sort of family dispute.

The obvious rift with his sister has left Bill in an unenviable position. He tells TMZ ... "In the span of less than a month I lost both my father William Bellamy Senior and my father-in-law Bernard Baker Junior. These two wonderful men that have impacted my life and my family's lives in ways that are beyond words."
