Three adults claiming to be biological sons of a UN official have sued for maintenance and upkeep. The three want retired lieutenant colonel John Kimanzi, currently an official at the UN, to fund their college education.

Elijah Muthui, Nicholas Muindi and Paul Muthama said Kimanzi forced their mother and them out of their residential home at Kahawa Barracks in Nairobi in 2003.

They said their mother has been taking care of them without any assistance from their father as provided for by the Children's Act. "It has become increasingly difficult for me to provide for the three children as I retired from Kenya Prison Forces on medical grounds," says Priscilla Katiti, their mother.

Katiti said her sons are in "dire need" of college education but their biological father has failed to honour his parental responsibility. "Their father is capable but unwilling to maintain them. He has been in gainful employment and is still earning his retirement benefits having retired recently as a lieutenant colonel in the Kenya Armed Forces. He is currently working with UN," Katiti said.

The three are seeking orders to compel their father to deposit their school fees to their respective colleges upon admission. Katiti wants the parental responsibility of her three sons be extended beyond their 18 birthday. The case will be heard on December 4.
