Disclaiming part of an inheritance

I know it is possible to disclaim an inheritance of eg 100 acres of land. But can I disclaim say 80 acres and inherit 20 acres so that I do not have to pay a big inheritance tax bill?

Thanks

My understanding is that it is all or nothing.

Well

Have you checked into Agricultural relief?

What happens if there are say 15 people on a will.... 5 are deceased, 5 have signed disclaimers and the other 5 have taken no legal steps?

what is the relationship bewteen you and the donor?
