1. If the gift is left ring fenced in your name at his request then your father could write a letter of gift and this would give some protection in the event of a divorce. However, if you invest the money in the marriage or purchase marital assets, the court would be able to take these into account in any division of property. 2. If your father dies within 7 years of the gift it would be added back to his estate for Inheritance Tax purposes if it is over £3000. If he survives for 7 years it will not. I hope that helps. Please leave a positive rating so that I am credited for my time.
