Expression of Wish
Also often called a Nomination form, this is the form you must
complete in order to nominate the person(s) you want to receive
your lump sum death-in-service benefits.
The pension scheme trustees do not have to
follow the instructions you give them but in the majority of cases
they will do.
If your circumstances change (e.g. if you get
divorced or remarried or have children) you must complete a new
form so the trustees know what your wishes are.
