Well yeah, many parents will pay something towards their DC's wedding. We paid a third towards our DD's wedding, her DH's parents paid a third, and DD and her DH paid a third. Around £4K each. If I was to message DD back and ask for the £4K back, she'd laugh. She'd laugh at the ridiculousness of it ... Who DOES that? 
As @mindutopia said, it's sometimes best to not take money off ANYone, as they can - and will - use it against you if things go a bit 'wrong.' (And you have a falling out.) They will hold it against you.
One of my friends was in a tiny 2 bed terraced house, and she and her DH had twins, and the house just became too small. They couldn't afford to upsize. So in 2023, her dad said he would give her £85K towards a 4 bed house - literally two - to two and a half times bigger.
He and her mum lived in Spain and had lived there since 2017. He said 'at least we'll have somewhere to stay when we come to visit instead of getting a Travelodge.' Only stipulation was that he goes on the deeds too. She and her DH weren't keen, but needed to upsize, so agreed. (This was early summer 2023.)
BIG mistake.
Earlier this year, less than 2 years after they bought the house, her mum and dad announced that they're coming back to the UK, and are moving in! 😱The dad's name is on the deeds, so he is a co-owner. Now, 5-6 months later he is still there. And her mum too. My friend HATES it, and says they are so intrusive and judgy and nosey, and it's putting a huge strain on her marriage.
Why the hell she let her dad onto the deeds just baffles me!
I'd have stayed in the tiny house and just made do!
