0317_Afeni-Shakur_tupac_getty-3Tupac Shakur's mom is getting divorced, TMZ has learned, and her husband wants half of that Tupac money.

Afeni Shakur filed for divorce against Gust Davis, her husband of 12 years. For some reason we're told the couple doesn't have a prenup.

Afeni filed in North Carolina, where judges are not required to divide property 50/50, but rather on a case-by-case basis to determine what's fair. They have lots of property and he wants, among other things, the right to live on their 50 acre North Carolina ranch and wants the keys to the houseboats. Gust, who's a minister, also wants to keep his sweet Jag.

Gust also wants alimony. We're told the Tupac Estate rakes in around $900k a year, but according to Gust, after expenses Afeni gets around $20k a month. We're told he wants $10k a month for the rest of his life. 

As for Afeni, she's been separated from Gust for a little more than a year. She's currently living on a houseboat in Sausalito, CA.     

Afeni has filed legal docs asking the judge to shut down Gust's alimony request.
