Hakan Aysal, 40, was arrested for the murder of his wife Semra Aysal, 32, and their unborn baby while on holiday in Butterfly Valley in Mugla, Turkey.
Prosecutors allege Aysal brutally pushed his wife off the 1,000ft cliff so that he could cash in on the insurance he had taken out on her life.
The seven-months pregnant woman and her unborn child were both instantly killed following the incident in June 2018.
The couple had been taking pictures on the cliff, and prosecutors say the "accident" was in fact murder carried out by the husband.
They claimed his motive was cashing in on the insurance he previously took out.
In the indictment prepared for the crime of "deliberate murder" against the husband, it stated he planned the ordeal in order to get the guarantee of £40,865 from insurance.
Prosecutors claimed that the only reason they sat on top of the cliff for three hours was so that he could make sure no one was around.
As soon as he realised they were alone, he deliberately killed her by pushing her off the cliff, according to prosecutors.
The indictment also noted that Aysal had claimed the insurance payment a short while later, but it was declined when news of the investigation was unveiled.
The Fethiye High Criminal Court has ruled that he be remanded in custody for premeditated murder.
In a video interview, the court heard from the victim’s brother, Naim Yolcu, who said: "When we went to the Forensic Medicine Institute to get the body, Hakan was sitting in the car.
"My family and I were destroyed, but Hakan did not even appear sad."
He added: "My sister was always against taking out loans. However, after she died, we learned that she had three loans taken by Hakan on behalf of my sister.
"Also, Hakan had a fear of heights, what extreme sport is she going to be doing when she is scared of heights?"
Asked about the questionable insurance premiums, Aysal said: "I have been interested in extreme sports since 2014; parachute, bungee jumping, rafting. That is why I had life insurance before I got married."
Aysal was also asked about the article in the accident personal insurance which stated that he was the heir if she died.
Aysal said: "I did not examine the policy much. The banker arranged the paperwork.
"I just brought it to my wife to get it signed. I was not aware that there was such an article."
He has denied being responsible for her death, saying: "After taking a photo, my wife put the phone in her bag.
"Later she asked me to give her the phone. I got up and then heard my wife scream behind me when I walked a few steps away to get the phone from her bag.
"When I turned back, she was not there. I did not push my wife."
The investigation is ongoing.
