Worked examples
A will survives as a photograph. The family has three letters and a bank form. For each item, record its custodian, date and the basis for attributing its signature to the deceased. A signature on a traceable form answers a different question from a name typed by a relative.
Seek material from around the date of the will, including signatures that look different from one another. Supply complete items and identify the copies. If the original will still exists, leave it unmarked and ask the examiner how to deliver it.
