IHT transferable nil rate

Descrabled

My first wife died in the late 80s and all her small assets passed directly to me. Does the transferable nil rate apply at 100%.

My second wife died in 2010 and used most of her nil rate band to provide for her children through 50% of the value of our house amounting to about 90% of the then nil rate band.

My third wife's will gives all her assets to me if she dies before me.

What is my transferable nil rate band?

Assuming she dies first your executor can cram the full transferable NRB from either your first or third wife. If you die first the full amount can be used from your first wife, but if you are leaving your estate to your third wife it won’t be needed.
