離婚 FAQ – 通姦 (Adultery)

Q1: 在香港，什麼是「通姦」？

A (中文)：通姦是指 已婚人士與異性發生自願性行為，而對方並非其配偶。同性關係或純粹的精神出軌（如曖昧或談戀愛）並不算通姦，但可能屬於「行為不合理」。
A (English): Adultery means voluntary sexual intercourse between a married person and someone of the opposite sex who is not their spouse. Same-sex relationships or emotional affairs do not legally count as adultery, but may amount to “unreasonable behaviour”.

Q2: 如何證明配偶通姦？

A (中文)：

• 直接證據：如承認、照片或錄影（較罕見）
• 間接證據：例如證明配偶與第三者同住酒店、長時間單獨相處
• 自白：如對方承認通姦，法院一般會直接接受

A (English):

• Direct evidence: e.g. admission, photos, or video (rare)
• Circumstantial evidence: e.g. staying overnight in a hotel with a third party
• Admission: if the respondent admits, the court usually accepts without further proof

Q3: 如果我知道對方通姦，但還繼續一起住，會怎樣？

A (中文)：如果在知道對方通姦後 仍同居超過 6 個月，法律會視為「原諒」(condonation)，就不能再以通姦作為離婚理由。你需要依靠其他理由（例如「行為不合理」或「分居」）。
A (English): If you continue to live together for more than 6 months after discovering adultery, the law treats it as “forgiveness” (condonation). You cannot rely on adultery as a ground anymore, and must use another fact such as “unreasonable behaviour” or “separation”.

Q4: 誰可以用「通姦」作為離婚理由？

A (中文)：只有「受害一方」可以提出。即：如果你是被通姦的一方，可以用這個理由。犯下通姦的一方不能以自己的通姦為理由離婚。
A (English): Only the “innocent spouse” can rely on adultery. The party who committed adultery cannot use their own adultery as a reason to divorce.

Q5: 有沒有真實案例？
