Known Donor Agreement

The English Family Court advises known donors and prospective parents to:

  • Obtain specialist legal advice at the outset, and
  • Enter into a written known donor agreement before conception

A written known donor agreement should be tailored to your personal situation, needs and wishes. It requires careful consideration and management of a range of complex legal and practical issues. It can be even more complex when there is an international dimension, a previous close or personal relationship exists between the parties, the parties seek to conceive by private arrangement and where parties need to navigate additional health and fertility issues.

A written known donor agreement has a number of functions, including:

  • Help understanding and navigation of legal issues and risks.
  • Tool to aid communication.
  • Tool to manage expectations and wishes.
  • Evidential use in the event of a subsequent dispute and litigation.
