H.W. Fowler’s opinion was that in using presume, the speaker believes the supposition is true and will believe it until he learns otherwise. In using assume, the speaker feels no certainty that his supposition is true or not.
In a legal context, presume means “to take as proved until contrary evidence is presented.” Ex. The defendant is presumed innocent.
Because of the association of the word presume with legal contexts, it carries a connotation of formality. For the fiction writer, presume would be the preferable choice in the speech of a remote or officious character. (Reference Daily Writing Tips).

The concept of reasonable courses through all considerations of the subject and is the cornerstone as to when trustees can recover costs. Being a trustee can be onerous, and at times, down right dangerous. The quid pro quo is reimbursement of costs – but such costs must be properly incurred. Trustees must not presume that all costs will be met.
Interestingly in Triezenberg v Mason notwithstanding that the reasonableness of the substantive application had not been decided, having formed a view that the trustees had acted reasonably (on the face of contested evidence) the trustees were entitled to an order that trust funds be made avilailable to meet their costs.
However, there was no corollary order to ensure “equality” between the parties. The test being whether it could be satisfactorily evidenced that the trustees had acted unreasonably in taking advice and pursuing proceedings.
Sometimes it is said that it is better to seek forgiveness than to ask permission. Trustees would be wise to never ever adopt this course of action.
