How long does the £10,000 need to be seasoned in my UK bank account for a Non-O marriage visa application?

Hello,

I posted another post but I think it’s pointless trying to come back to phuket to get a non o marriage visa based on my passport stamps with too many tourist entries.

I’ll probably get turned away, it’s not wort. The risk.

I’m going to apply as suggested to me to get a non o marriage visa before I leave the UK for Thailand.

My only question is the £10,000 I have to show on an official document when applying, how long does it need to be seasoned in my UK bank account?

Is it only 1 day?

Or 2 months?

I went on the royal thai embassy of London and it doesn’t say a period of time.

Just that I have to prove I have those funds in my account.

I have my money in investments and I can put the £10k into my bank account today and apply if it’s only 1 day.

Thanks in advance 🙏
