Leaving a gift in your Will

As a charity dependent on public support, the Zoological Society of London (ZSL) relies on future gifts in Wills to help to continue its work.

Once you have accounted for your family and friends; including a gift to ZSL in your Will can make a lasting contribution to the worldwide conservation of animals and their habitats well into the future.

Gifts in Wills

A legacy gift left to ZSL as a whole, usually “for general purposes”, is the most useful because ZSL can then use it where the need is greatest at the time of receiving the gift, which could be 20 or 30 years after the Will was made.

However, at ZSL you can leave a legacy gift to an area of our work such as ZSL London Zoo, ZSL Whipsnade Zoo, ZSL Veterinary Services Department, ZSL Conservation Programmes, The Institute of Zoology or ZSL Library.

We would advise against being too specific in order to guard against future problems. For example, if a legacy gift is left expressly for a specific project that the charity has already carried out, the charity may not be able to receive your gift.

If you did want to leave a legacy gift to a particular area of ZSL, it’s useful to include the words “but without imposing a binding obligation” in your Will.

Financial benefits of leaving a gift in your Will

A legacy to charity is generally exempt from inheritance tax, so a gift in your Will to the Zoological Society of London could reduce the level of tax payable on your estate when you die.
