Unfortunately the rules have now been amended and specifically say that the money can only be in the name of the applicant or the applicants parents or legal guardian, therefore I don't think you can rely on this case. Presumably your friend is an adult and therefore I am not sure her husband could be appointed her legal guardian now but I suppose it depends on how things work in her country. It would be far easier if the money was in her name or a joint account with her husband.

Appendix C para 13
