My FIL recently passed away leaving his estate to his 2 children- my DH and my SIL. A couple of years ago my SIL had a new car, there was no conversation about the car, and none was expected other than “What a lovely car” etc. It was just assumed she had bought it herself. When my DH and SIL were sorting through FIL papers they discovered that the my FIL had been paying for the car on finance. SIL said that she had believed it was an outright gift from him and was surprised that it still had £5K debt to pay on it. They are now having a disagreement about whether she should receive the outstanding £5K in addition to her half of the estate, or whether it should be included within her half of the estate.
I’d be grateful to get a wider perspective on this to help resolve it.
