A solicitors in Hassocks has partnered with the Chailey Heritage Foundation to support its annual Make a Will Fortnight campaign.
Griffith Smith LLP in Keymer Road is offering free will appointments from September 10-21.
However, individuals are requested to consider a donation to the charity.
Suggested donation amounts are £75 to add a Codicil to an existing Will, £120 for a Single Will and £180 for Mirror Wills.
A spokesman said: “According to a 2016 survey, only 37 per cent of the British public have made a will.
“Writing a Will doesn’t just give you peace of mind. It ensures that your wishes will be respected and also saves your loved ones from added stress when the time comes.
“If you don’t yet have a will, or you need to make changes to your will, this is an opportunity to do so.”
