Cash gift from friends and family outside UK

I am a pre-settled EU citizen (soon would be settled) planning to buy a home in the UK. My sister-in-law, who lives overseas, wants to give us a cash gift of £200k towards the deposit for our first home. I have a few questions: 1) Can a non-UK resident family member, like a sister-in-law or even a friend, give a cash gift for a property purchase? 2) Is there a limit on the amount of cash gifts that can be received from overseas? 3) Will I need to pay tax on this cash gift? 4) What documents do I need to provide to HMRC to prove the gift?

Hi,
There are no tax implication on the giving or receiving of cash gifts. There is no limit to giving or receiving a cash gift. Any interet the cash gift generates, is taxable and should be declared. You do not need to declare the cash gift.
Thank you.
