My mother's estate is in probate. I have a general idea of the value of the estate and it's over the 8938 threshold, but obviously sales of shares, the house and bills make it difficult to exactly value and the solicitor won't be providing a final accounting until the estate is out of probate. I received an initial bequest from the estate in 2014 of ~$30k....would that be the value I should use for 8938 purposes?
