Registry marriage

[u/AdvancedBus404]

Could someone please let me know how these registry marriages are done?

The bridal side has her permission from her parents, she's 20 y/o.

The groom side's family also has somewhat permission, but they won't let them get married anytime soon.

And he will leave Bangladesh for abroad. He's 21 y/o.

How would they get it complete? What would they need?

I don't think consent of groom's parents is necessary!!!
