At Thursdays hearing, the Seoul High Court will set the order of witnesses and evidence for the appeal trial, which is expected to begin in mid-October.
Since Lee filed for appeal late last month, the appellate court is likely to try to rule by next January, as under Korean law, he can only be kept in detention a maximum of four months while the court considers his appeal.
Whichever side loses is likely to appeal again to the Supreme Court.
Four other Samsung executives were also convicted in the lower court in the bribery case.
Lees legal team has added new lawyers for the appeal, including former Seoul Central District Court chief and new lead counsel Lee In-jae.
Earlier this month, the defence team laid out its strategy submitted in hundreds of pages of arguments to the High Court.
The defence is expected to question the lower courts logic that Lee expected Parks help in "succession operations," which the court defined as all actions Samsung affiliates took "to strengthen Lees control of Samsung Electronics."
Lees defence has argued there was no such thing as "succession operations" and actions such as a 2015 merger of two Samsung affiliates was taken for the companies own perceived profit.
The lower court ruled that while Lee never asked for Parks help directly, the fact that the merger did help cement Lees control over Samsung Electronics "implied" he was asking for the presidents help.
Another defence argument turns on whether there was in fact a bribe as defined under South Korean law, which says only civil servants come under the statute. Lee was found guilty of providing financial support for former president Parks close friend and confidante, who was not a civil servant.
The lower court found that Samsung provided financial support to entities backed by Parks friend Choi Soon-sil, including 7.2 billion won ($6.4 million) to sponsor the equestrian career of Chois daughter.
The court said this was a straightforward case of bribery as "it can be considered the same as she (Park) herself receiving it." Lees defense is expected to argue no evidence exists to back that assertion.
Lees defence counsel at law firm Bae, Kim & Lee LLC declined comment.
Lee testified during the trial he had limited knowledge and authority over business decisions in affiliates except Samsung Electronics and related tech affiliates, which took up about 90 per cent of his work.
His lower court trial began after Park was impeached, but before her successor, President Moon Jae-in, a liberal critic of the conglomerates known as chaebol, was elected in a special presidential vote in May.
