Hello and thank you for your question. I will be very pleased to assist you. I'm a practicing lawyer in England with over 10 years experience.
May I clarify that this relates to England and Wales please?
Thanks. It is lawful for cousins to marry in England and Wales. This has been the case for a very long time. Marriage between other genetic relatives is not allowed with the exception of cousin - cousin marriages.
Is there anything above I can clarify for you?
