#Practical implications
#Amicus strategy: meet Mumo Matemu test
When applying to appear as amicus curiae in the Supreme Court, ensure your client demonstrates expertise, independence, impartiality, and public interest as per Mumo Matemu. The court will scrutinise these elements even if the respondent objects. Prepare a focused brief that shows how your client’s input will assist the court on specific legal issues.
NGOs can influence family property law
Businesses involved in property or family law should note that the Supreme Court is open to expert input from civil society on cohabitation property rights. This ruling signals that the court values comparative analysis from experienced organisations. If your business relies on clear property rules, monitor this case as it may shape future division of assets for unmarried couples.
Cohabitation property rights under review
If you are in a cohabiting relationship not recognised as marriage, this case could affect how property is divided if you separate. The Supreme Court is considering legal frameworks for such situations. An expert NGO is now helping the court. Stay informed because the outcome may change your rights when acquiring assets with a partner.
