We strongly recommend you have your Will drafted by a solicitor to ensure your wishes are properly carried out. Here are some examples you may find useful:
Residuary Gift (the remains of your estate after any specific gifts have been distributed, and any debts have been paid):
“I give free of Inheritance Tax (…%) of the residue of my estate to The Guide Dogs for the Blind Association…”
A Pecuniary Gift (a specific sum):
“I give free of Inheritance Tax the sum of...pounds to The Guide Dogs for the Blind Association…”
Then follow with:
“…whose Registered Office is situated at Hillfields, Burghfield Common, Reading, Berkshire RG7 3YG (Registered Charity No. 209617 or SC038979 or 1334), for the general charitable purposes of the Association, and I declare that the receipt of an authorised official for the time being shall be a good discharge to my executors.”
For a pecuniary gift, you may wish your gift to be adjusted for inflation. We suggest you see a solicitor for suitable wording.
