Leave something intelligible behind
An executor should not have to discover an obscure private-company investment from an old email or share certificate.
A durable ownership record
A Passport can record what the company is, what you believe you own, the evidence supporting the holding and useful company information gathered from public sources.
It can then give executors or advisers a much clearer starting point if the holding later needs to be dealt with as part of an estate.
Unquoted shares can create an awkward problem for an executor: the holding has to be identified and may need to be valued even though there is no readily observable market price. Establishing whether an obscure holding has significant value — or virtually none — can require specialist work and affect the estate’s tax position. A well-maintained Passport gives the executor a much better starting point and could later be used with Bad Angel’s sale-preparation tools to help the executor or their adviser resolve uncertainty quickly.
