This is the narrow one and I say it to the lawyers and they all nod and about a third of them go slightly still.

Detached signature pages are ordinary commercial practice.

They are also the entire mechanism of what happened to my family, and it required no skill whatsoever.

Number them page 3 of 4.

Sign the whole thing as a scan and keep your own copy, dated, of what you signed, with the pages in it.

It takes about ninety seconds per document.

I sign around six hundred a year.
