Love marriage

I am looking for someone who can provide guidance on the legal requirements for a love marriage. I am not looking for assistance in a specific country's marriage laws, but rather general information that can be applied universally. I have some specific issues and concerns that I am anticipating and would like someone who can address those. Ideal skills and experience for this job include knowledge of marriage laws and regulations, experience in dealing with cultural barriers, and the ability to provide support in navigating family objections.
