A scheme to attract donations in return for will-writing services raised more than £1m in donations and £5.3m in legacies for nine charities last year.
The Will Aid scheme involves recruiting volunteer solicitors to draw up basic wills and encourage clients to donate to charity rather than paying the usual fee. Nine thousand people took part in the scheme during November.
Claire Routley, chair of Will Aid, said: "The income from this appeal makes a fantastic difference to our work with vulnerable people in the UK and all around the world. The campaign will run again in November 2010 with the same partner charities, and we hope that its appeal will continue to grow."
