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?
