Legal advice! Annulling a marriage.

I guess I should start this by saying me and my boyfriend are both Pimo.

We've been together for awhile but we're being forced to get married before moving in together.

We both want to get married in the future but our family is forcing us to do now, or we have no support.

We have been trying to brainstorm for ways to get the marriage certificate but not actually be married. Wether we annull right after. Don't consumate and get annulled.

We're pretty desperate and need some advice.

I don't know if it's even possible to keep the marriage certificate after an annulment. Having the certificate is kinda important for proof that we're 'married'
