An Affidavit of No Marriage in Kenya, also known as an Affidavit of No Impediment to Marriage, is a sworn statement confirming that an individual is single and legally free to marry. It is often required by registrars, religious institutions, or foreign embassies when applying for marriage in Kenya or abroad.

The document is signed before a Commissioner for Oaths or Notary Public and may need to be authenticated for use outside Kenya. It assures authorities that no prior marriage exists, which would make the intended union unlawful.
