If your father in-law is considering gifting higher amounts of cash, but doesn't feel he is able to as he needs to keep money behind for his own use, a Discounted Gift Trust may be useful here.
This would allow him to gift a sum of cash to you, but would allow him to take a regular tax free income from the gift he has given you, for life. This would not break any IHT rules, including Gift with reservation of benefit, and finance Act 2004 too.
This means ultimately you would reduce very much more any IHT bill in the end.
Feel free to contact me directly if you want more info on this.
