Any person wishing to make the Altrincham Branch a beneficiary in their will should use these words:
"I give £____ to the Royal Society for the Prevention of Cruelty to Animals ALTRINCHAM Branch and I
declare that the receipt of the Honorary Treasurer or other proper officer for the time being of the said Branch shall be a
full and sufficient discharge for the said legacy"
If you already have a will, your solicitor can add it to a section (a 'codicil') based on the above words.
