A trust, known as the Great Stone Bridge Trust, was created, possibly as early as 1511, due, it is said, to complaints made by two ladies of the parish (probably an Urban Legend) who found it inconvenient to reach the church accross the stepping stones, which does not say much for Mathew Mowshurst's repairs of 1447.

It was customary in those times to bequeath money to fund the upkeep of roads and bridges and, whether or not the two ladies were involved, moneys were found and were administered by the Great Stone Bridge Trust, Which still exists today.

The Trustees are a group of local people, at present nine in number. They are responsible to the Charity Commission, set up in 1853, for ensuring that the original concept of the bridge being for the benefit of the people of Edenbridge is upheld.

The Trust's remit even extends nowadays to educational matters such as offering grants to individuals. For example the Trust has materially contributed to the cost of setting up the Eden Valley Museum.
