Marriage banns, also known as "publications of marriage," are a legal requirement in the Philippines before a couple can get married. The purpose of the banns is to ensure that there are no legal impediments to the marriage and to give the public an opportunity to object to the union.

The process of obtaining marriage banns begins with the couple obtaining a marriage license from the local government office. The couple must present several documents, including their birth certificates, baptismal certificates, and a certificate of no impediment to marriage. They must also provide proof that they have undergone pre-marital counseling.

Once the couple has obtained the marriage license, they must then have the banns posted in a public place, such as the local church or town hall. The banns must be posted for three consecutive Sundays before the wedding date, giving the public an opportunity to object to the marriage.

If there are no objections, the couple can proceed with their wedding. However, if there are objections, the couple must resolve the issue before they can proceed with their wedding. This could include proving that any legal impediments to the marriage have been resolved or addressing any concerns raised by objectors.

It is important to note that marriage banns are unique to the Philippines, and that the process may vary slightly depending on the specific region or municipality. It is always best to check with the local government office or church for specific requirements.

In summary, marriage banns are a legal requirement in the Philippines before a couple can get married. It is a process of posting the couple's intention of marriage in a public place for three consecutive Sundays before the wedding date, giving the public an opportunity to object to the marriage. If there are no objections, the couple can proceed with their wedding, otherwise, they must resolve the issues before they can proceed with their wedding.
