Former Queensland real estate agent Gerard Baden-Clay is due to appeal his conviction for murdering wife Allison in August.

A hearing has been set down for August 7 in Queensland's Court of Appeal.

The 44-year-old father-of-three is serving a life sentence after he was convicted last July of murdering his 43-year-old wife at their Brisbane home.

Appeal documents lodged two days after Baden-Clay's conviction outlined several grounds for challenge.

They include that the conviction was unreasonable, that there had been a miscarriage of justice and that the judge had made errors in his directions to jurors.

Allison Baden-Clay's body was found on a west Brisbane creek bank at Anstead on April 30 2012, 10 days after her husband reported her missing.

Baden-Clay, once a successful property agent, was charged with murder in June 2012.

Details of the pair's crumbling marriage, financial problems and Baden-Clay's multiple infidelities were aired at his Brisbane Supreme Court trial.
