Who gives you away? Whoever you want to.
Nobody has to give you away — it isn't a legal requirement, it isn't a humanist requirement, and it's one of the first assumptions I ask couples to drop when we start planning. The processional is just the bit before the ceremony starts. What actually matters is who you want beside you when it happens, and there's no single right answer.
The real options
Walking in with a parent is still lovely, and plenty of couples choose it because it feels right for their family — nothing wrong with tradition when it's actually chosen rather than assumed. But it's one option among many. Both partners can walk in together, side by side, which is what Chris & David chose at House for an Art Lover — two grooms, one entrance, no "giving away" required or expected. A couple can walk in with both parents, one on each arm. Siblings can walk each other in. Children can walk in with a parent. A dog can lead the way. Or — just as validly — everyone can simply already be in the room, no processional at all, and the ceremony starts exactly where you are.
Blended families and who to include
This is where the old assumption causes the most quiet stress — whose dad walks you in, if you have two, or none, or a step-parent who's been more present than a biological one. There's no rulebook here, only the honest answer: whoever has actually been there for you. A step-parent walking you in is exactly as real as a biological one. So is being walked in by your mum, your best friend, your kids, or all of the above at once. I ask every couple who they'd genuinely want beside them for those thirty seconds, without worrying about who "should" do it — and the answer is almost always someone specific, once the assumption is out of the way.
Good to know
Whatever you choose, tell your musician or playlist person the timing in advance — a walk-in song needs to match the actual walking pace of whoever's coming down the aisle, not a wedding-video pace. If two or more people are walking in separately (say, each partner with their own parent), agree the order beforehand so it isn't decided awkwardly in the doorway. And if you'd rather skip the processional altogether and have guests already seated when you enter — or skip an entrance entirely and simply begin — that's a complete ceremony too, not a lesser one. I've stood at the front of rooms that started every one of these ways, and none of them made the marriage any less real.
