The divorce attorney for Nina Reiser says the missing woman's husband, Hans Reiser, failed to pay thousands in child support and that divorce proceedings were "very hostile."
Thirty-one-year-old Nina Reiser disappeared in September 2006 after dropping off her son and daughter at Hans Reiser's Oakland home.
Even though a body has never been found, her husband has been
charged with murder.
The defense maintains that she might be living in her native Russia.
On Tuesday, Hans Reiser's attorney aggressively questioned the divorce attorney, Shelley Gordon, asking whether Nina Reiser's estate would have any stake in Hans Reiser's computer company, Namesys, if he is convicted of murder.
Gordon said yes, but added that the computer company is valueless.
