Eh, I haven't actually given birth at Muar Hospital myself, but a few of my mum friends who bersalin there said the standard ones lah, your IC, husband's IC, marriage cert, and your antenatal card (the pink/blue booklet from clinic). Best to call the hospital directly first though, sebab sometimes they add extra requirements or specific forms they need, and better safe than sorry when you're already in labour! Do check with them a day or two before your due date to confirm everything, easier than rushing around last minute.
