Informacion Matrimonial

Hello Nuestros Ranchos Forum,

In Ancestry trees they have a drop down box for marriages that says MArriage Bann, Marriage License and Marriage Contract, does anyone know what the Informacion Matrimonial is? is it a marriage bann, marriage license or marriage contract? i thought maybe it was a marriage contract, but then i thought maybe a dowry was a marriage contract. ?
