Mr Kipng'etich's mother, Naomi Jeptoo, who was divorced by Mzee Kibor two years ago, backed her son's position.
Justice Anthony Ombwayo of the Land and Environment Court in Eldoret ruled that Mr Kibor is the legal owner of the land and that his sons did not have valid documents to claim ownership of the property.
Mr Kibor, who owns acres of land in Uasin Gishu and Trans Nzoia counties, convinced the court to strike out documents showing that the land in dispute was transferred to his embattled sons.
After winning the four-year court battle against his sons over the multimillion agricultural land, Mr Kibor said he must also get back the gun that was confiscated following an incident with the sons in 2018 over land.
His sons rejected Mr Kibor's claim regarding his security and cautioned the government against giving him back his gun before subjecting him to the requisite tests.
