President Joko Widodo won 55.5 per cent of votes in the poll to lead the world's third-biggest democracy, beating retired general Prabowo, who got 44.5 per cent, the General Election Commission (KPU).
The election supervisory agency has said previously there was no evidence of systematic cheating and independent observers have said the poll was free and fair.
"Hopefully this will be a part of realising a democratic nation that is based on the rule of law," said lawyer Bambang Widjojanto while handing over a thick dossier to the Constitutional Court late on Friday.
After the KPU's announcement this week, Prabowo repeated earlier claims that there had been widespread cheating in favour of the incumbent and thousands of his supporters protested against the result in the capital, at times violently.
Eight people were killed, including three teenagers, while more than 900 were hurt in two nights of rioting and clashes between police and protesters, Jakarta Governor Anies Baswedan and the city health department said.
The Constitutional Court is scheduled to hold the first hearing on the case on June 14 and to deliver a verdict on June 28, according to court spokesman Fajar Laksono.
An exit poll conducted by pollster Indikator Politik Indonesia on election day showed that 94 per cent of voters believed the election had been free and fair.
Police have arrested hundreds of people accused of taking part in the riots or provoking violence, two of whom were members of a militant group that had pledged support for Islamic State, national police spokesman Muhammad Iqbal said.
A small number of protesters gathered peacefully near the Constitutional Court on Friday.
The government has deployed 58,000 police and soldiers across Jakarta to maintain security and put temporary blocks on some social media to prevent unrest sparked by fake news.
