Or do we have to let them know.
We applied for probate, didn't bother with inheritance tax form as it's below the threshold.
HMRC wrote to us saying we did need to fill in the IHT400 after all, which I did. We've received a letter from them saying we don't need to pay inheritance tax, but also giving us a code and saying we can now 'apply for probate'.
Can't get hold of anyone in probate office and DH seems to think the HMRC will have notified them directly.
This is all such a ball ache.
