Background: People with intellectual disabilities are at increased risk of forced marriage compared to those without intellectual disabilities. In the UK, this risk is particularly, though not exclusively, associated with South Asian communities and is linked to the desire to secure long-term care. Method: Focus groups and semi-structured interviews were undertaken with South Asian parents and family carers (n = 22) of adults with intellectual disability and the resultant data thematically analysed. Results: Although securing care for their intellectually disabled relative was identified as a key motivator for forced marriage, other important themes also emerged. These included cultural and religious beliefs about disability and marriage, and limited understanding of relevant laws. Factors militating against forced marriage were also identified, including fears of abuse and neglect. Conclusions: Implications for the provision of services and the need for improved access to information on forced marriage of people with intellectual disabilities are highlighted.
