The Institute of Fundraising is to publish additional guidance for charities on whether to accept or refuse donations.
A spokeswoman told Third Sector that discussions on the guidance had started earlier this year and had not been inspired by the recent debate about whether charities should accept donations from the News of the World.
The guidance, which has a working title of Gift Acceptance Processes, will sit alongside the IoF's Acceptance or Refusal of Donations Code of Fundraising Practice.
The institute pointed charities to its code last week when it advised them to be cautious about accepting offers of free advertising in the last edition of News of the World.
The spokeswoman said: "We feel it's something that requires extra guidance. Sometimes, these issues can be quite high-profile and there is increasing awareness of where charity gifts come from."
She said the guidance was likely to include extra information on what to look for when researching donors. It will also encourage charities to think about who should make decisions about whether to accept gifts.
No publication date has been set for the guidance. The institute's policy team is working with its Researchers in Fundraising special interest group to put the guidance together.
