Sinha assumed office on January 17, 2015 as the country's 21st Chief Justice. He is scheduled to retire on January 31 next.
"His (Sinha's) resignation letter has reached Bangabhaban (presidential palace)," President's press secretary Joynal Abedin told PTI without elaborating, but legal experts said this confirmation meant that Sinha has quit his office.
Officials familiar with the development said, Sinha submitted his resignation letter to Bangladesh Embassy in Singapore on the last day of his month-long leave yesterday, where he had gone for medical checkups.
Before his departure, Sinha had said that he was "embarrassed" over the controversy surrounding his July ruling.

"I am the guardian of the judiciary, in the interest of the judiciary, I am leaving temporarily so that its image does not get hurt. I will return," he briefly told newsmen before leaving Dhaka.
Row with the government and the higher judiciary started in July this year when the apex court declared as void the 16th constitutional amendment, scrapping Parliament's authority in impeaching SC judges.
Before leaving home, Sinha said he "firmly believes" that his stance over the verdict was misinterpreted to the government, upsetting Prime Minister Sheikh Hasina but expected her to realise soon the fact.
A day after his departure, the Supreme Court issued a statement saying that other judges of the apex court had decided not to sit in the bench with Sinha over allegations of "grave" graft and moral lapses, brought to their notice by President Abdul Hamid.
It said the allegations included some grave charges like money laundering, financial irregularities, corruption and moral lapses.
In unitary Bangladesh, the Supreme Court has two wings, the High Court Division and the apex Appellate Division.
According to the SC statement, all the five apex court judges held a meeting on the next day and subsequently met Sinha and sought his explanation about the allegations but "didn't get any acceptable explanation or reply".
Former Prime Minister Khaleda Zia-led main opposition outside parliament, BNP had put their weight behind Sinha while its standing Committee Member and former law minister Moudud Ahmed blamed the government for "forcing" him to quit.
"Sinha's resignation day will be marked as a black chapter," he said accusing the government of "smashing independence" in the judiciary.
The President had appointed senior most judge of the apex court Abdul Wahhab Miah as the acting chief justice. According to Bangladesh Constitution, if the chief justice's office becomes vacant, the next senior most judge of the Appellate Division will perform his duties.
