An Unabridged Marriage Certificate is a legal document which lists all information concerning a marriage such as the names of two spouses, the spouses ID numbers, the date and the place of marriage. In comparison with an abridged certificate, the unabridged one, contrary to an abridged one, discloses all data and is accepted throughout the world. Many times they are demanded when applying to immigrate, when processing visas, when it comes to dual citizenship, legal transactions in a foreign country, and official procedures when detailed evidence of marriage is required. This is particularly valuable when either or both spouses are seeking home country residency and/or citizenship and work permits. Possession of a marriage certificate in its full form helps in absence of delays or problems in the matters of law, traveling, or documentation. It gives genuine, comprehensive proof of marriage status which is the reason why it becomes an important document in any marriage which has to face international legal or administrative issues. Always retain one copy certified so as to have it in future use.
