Tim Duncan -- NBA Star Says He's Too Busy to Get Divorced

NBA superstar Tim Duncan has filed legal docs in his divorce case, asking the judge to put the brakes on the dissolution of his marriage until the San Antonio Spurs clinch the NBA championship.

TMZ has obtained legal docs filed in Bexar County, Texas, in which Duncan makes the case that his employment "is currently making extraordinary demands on him and hopefully will continue to make those demands for the next 30 or so days." Translation -- he's banking on a ring.

Duncan's wife, Amy, filed for divorce in March, saying she wanted to end their 12-year marriage which she says has become "insupportable because of discord and conflict."

In the docs, Duncan reveals he has a prenup, which he wants enforced. This is important because Duncan got married 4 years AFTER he was selected in the first round of the NBA draft. In 2012, he inked a 3-year, $36 million deal, and that's just the last contract. Dude is worth a fortune.

Duncan also says he expects he and Amy will reach an agreement on financial support for their two small kids.
