• The MSP for Aberdeen Donside died on Thursday following a battle with cancer
• Mr Adam’s family hope the service can be “a suitable celebration of Brian’s life and legacy”
• They have asked mourners to “avoid sombre attire”.
Mr Adam died at home on Thursday, aged 64, following a battle with cancer.
The service will be held at the city’s Church of Jesus Christ of Latter-Day Saints on North Anderson Drive at 12.30pm.
Mr Adam lived in Aberdeen and served as a constituency MSP for Aberdeen Donside, having been first elected to Holyrood as a list member in 1999.
His funeral is expected to be attended by friends and colleagues from across the political divide.
First Minister Alex Salmond last week led the tributes to Mr Adam - a former minister and SNP chief whip - describing him as “an exceptional MSP”. His remarks were echoed by leaders from the opposition parties.
Meanwhile, MSPs from all parties lined up to sign a book of condolence at the Scottish Parliament and the building’s flags were flown at half-mast as a mark of respect.
A spokesman for Mr Adam’s family stated: “We have been deeply touched by all of the messages of sympathy and acts of kindness during this difficult time. It has been remarkable to see just how many lives Brian touched.
“From the flags at half-mast, to the numerous press articles and interviews, each act of remembrance has been noticed and appreciated.
“Brian was a long-standing dedicated public servant and the tributes that have been paid to him have certainly reflected that.”
“Since we hope that Friday can be a suitable celebration of Brian’s life and legacy, we politely request that mourners avoid sombre attire.”
