"Registration as a British Citizen can be a complex issue. There are various circumstances in which an Applicant may be entitled to either register as a British citizen, or already be British without knowing. For example, this could be due to a historical injustice, as nationality law has not always treated men and women equally. In addition, children of unmarried couples (or couples where the mother was married to someone other than the natural father) were historically treated differently to children of married couples. 

The legislation in this area is complex and it can be difficult to obtain the relevant documentation to support an application. Therefore, legal advice should be sought when preparing an application.

The legal team at OTB Legal have significant experience in gaining successful outcomes for applicants seeking to register as British. If you think that you may be eligible to register as British, or may already be British, why not contact us to discuss your enquiry further?”
