we don’t have a form as such. We usually pre-authorise any trustee expenses at trust board meetings and the clerk refunds money on production of a receipt. We normally do this via e-mail with the reason for the expense in the subject line. For example I’m attending the 2025 members day, I paid my own fee and for my own train ticket. The Clerk will refund me at our next meeting (when a report by me on the members day will be on the agenda).
