The family of murdered real estate agent Allison Baden-Clay is disappointed after her husband's murder conviction was downgraded to manslaughter on appeal.

Gerard Baden-Clay was convicted of murdering his wife and mother of their children in 2014 and sentenced to life imprisonment.

In the Court of Appeal, Baden-Clay's lawyers argued there was no evidence of his intent to kill and on Tuesday, Chief Justice Catherine Holmes, Justice Hugh Fraser and Justice Robert Gotterson set aside the murder conviction, replacing it with the lesser charge of manslaughter.

A statement released by Allison's family said they were "disappointed by today's Court of Appeal decision, and remain supportive of the original findings of the court" saying they hoped "justice for Allison will be served".

"As always, the efforts of the family remain centred around the well-being of Allison's daughters, who now face a further period of uncertainty," the statement said.

Baden-Clay was convicted of murder after an extensive trial where a jury heard testimony of his financial troubles, the fact he checked his wife's life insurance policy the week she went missing and his mistress' requests for him to leave his wife.

The trial also covered photos of scratch marks he sustained to his face and chest the week his wife went missing. He claimed the marks were caused by shaving. During the extensive trial, Baden-Clay never admitted to any involvement in his wife's death, maintaining she vanished one evening.

Baden-Clay will be resentenced for manslaughter.
