A gift with reservation of benefit occurs when an individual transfers ownership of a property to someone else but continues to benefit from or use that property. (ELM Legal Services)

A gift with reservation of benefit is when you give something away, like a house, but you still get to use it or benefit from it somehow. For example, if you gift your house to your child but still live in it rent-free, that's a gift with reservation of benefit. (Lawhive)
