Prince Yuvaneath attended Sisowath High School in Phnom Penh where he learnt to speak French and English along with his native Khmer.

They would reside together in Beijing until Yuvaneath moved with his wife Tea Kim Yin to go live in Hong Kong.

His son Prince Norodom Ekcharin had died as a child in 1976 during the Khmer Rouge regime.
