The electoral petition seeks an order for the result to be declared null and void and a new election to be called within 60 days.
The MDC's 15 grounds include alleged bribery, abuse of "assisted voting" and manipulation of the electoral roll.
Mr Mugabe, 89, won with 61% of the presidential vote.
His Zanu-PF party gained a parliamentary majority of more than two-thirds, with 160 seats against 49 for the MDC.
The MDC is to file a complaint on the parliamentary results at a later date, reports the BBC's Brian Hungwe in the capital Harare.
With a two-thirds majority, Zanu-PF is able to amend the constitution, potentially restoring presidential powers which were reduced earlier this year.
'Turned away'
Lawyers for the MDC, which filed its petition with the country's constitutional court, told the BBC they had "strong evidence of electoral irregularities".
They said a shockingly high number of people were unable to vote at the polls, and that food and other bribes were used to persuade voters to back Mr Mugabe, our correspondent says.
"The Movement of Democratic Change has filed its election petition... what we seek is that this election be declared null and void in terms of section 93 of the constitution of Zimbabwe," said MDC spokesman Douglas Mwonzora.
The challenge comes a day after Zimbabwe's electoral commission said nearly 305,000 voters had been turned away from polling stations on election day. The MDC says the true number is about 900,000.
Mr Mugabe's margin of victory was some 940,000 votes.
A week after the election, Mr Mugabe dismissed criticism of the polls and lashed out at Western countries for their response.
Zimbabwe's nine-member constitutional court has up to 14 days to respond to the legal challenge.
Correspondents say some of the judges are believed to be Mugabe loyalists.
