"The criminal case has reached the Moscow City Court. The date for hearings is to be set within 30 days," press secretary Anna Usacheva said.
The key suspect in the case made an unsuccessful suicide attempt, a member of his defense team said last month.
Ruslan Koblev said his client, notary Fail Sadretdinov, tried to hang himself in a cell of the Butyrsky detention center in December, where he had been held for more than a year, but fellow inmates prevented him from doing so.
A jury earlier cleared Sadretdinov of murder charges, but the Supreme Court overturned the acquittal and ordered repeat hearings. The defendant also faces prosecution on unrelated charges of property fraud and money laundering. He has denied any wrongdoing, and said he was incriminated on fabricated evidence.
Chechens Kazbek Dukuzov and Musa Vakhayev are also defendants in the case.
Klebnikov had worked for Forbes since 1989 and gained a reputation for investigating murky post-Soviet business dealings and corruption. He became the first editor of Forbes Russia when it was launched in April 2004. He was shot dead on a Moscow street three months into the job.
