I am an Australian Citizen getting married in the Philippines.Will need a Moral Character Reference for Legal Capacity to Marriage there?

I don't know the rules for getting married in the Philippines, but being a citizen of Australian will NOT get you out of any requirements that would apply to a citizen of the Philippines. If anything, it will ADD requirements that only apply to foreigners.

Are you 10000% sure this marriage is going to last forever? I hate to be skeptical but divorce is not allowed in the Philippines and it can take 10+ years to get an annulment. Because of this if you have ANY sort of doubts you will be together until you die, consider marrying somewhere else

A Danish friend married a women in the Philippines. She came to Denmark for a few months and was miserable and homesick there and decided to go back home. They have been living apart for 5 years now and he wants to marry someone else and he can't. He can't divorce her as she is a resident of the Philippines. He's spent so much on a lawyer there trying to get an annulment but is told it takes 10 years or more

His wife is not a bad person, she was just too attached to her family and too homesick and couldn't live across the world from them. Had she been from another country, they could have divorced easily and quickly since they were only living together as a married couple for less than a year. But that's not the case since they married in the Philippines and she lives there.

So consider bringing her to Australia to marry there instead so you are covered under Australian law in case things don't work out.
