No, incestuous relationships, including dating siblings, are criminalized under Irish law. The Criminal Law (Sexual Offences) Act 2017 prohibits sexual relations between close family members, with penalties up to life imprisonment. Consent is irrelevant in such cases.
Key Regulations for Dating Siblings in Ireland
- Criminal Law (Sexual Offences) Act 2017: Explicitly criminalizes sexual acts between siblings, regardless of consent. Section 48 defines “incest” as sexual intercourse between lineal ancestors/descendants or siblings.
- Family Law Act 1995: Prohibits marriage or civil partnership between siblings, reinforcing the prohibition under the 2017 Act. Non-compliance voids such unions.
- Child and Family Agency (Tusla) Mandates: Tusla may intervene if minors are involved, assessing safeguarding risks under the Children First Act 2015. Even non-sexual sibling relationships may trigger welfare assessments.
Irish courts have upheld these provisions in cases like DP v. DPP (2019), where sibling relationships were deemed unlawful despite lack of coercion. The 2026 Criminal Justice (Sexual Offences) (Amendment) Bill proposes stricter penalties for incest involving minors, aligning with EU directives on familial sexual abuse. Legal professionals must advise clients against such relationships to avoid prosecution and civil liability.
