giving money to beneficiary

[bill on line]

Dear Group

Is it necessary for English discretionary and interest in possession trusts, that a deed (I am guessing deed of appointment or declaration of trust) is drawn up when the trustees decided to give beneficiary some money (cash)?

If deed is necessary, do all the trustees need to sign and be witnessed?

Or with all the trustees being in agreement I as the named account holder of the trust cash account distribute it, or can I just keep a simple record?

Thank your help in advance
