Husband Divorced Wife Who Insulted Their Landlord In Ekiti

Joseph Idowu, a 31-year-old man has divorced his wife of 5
years, Omolara who insulted their landlord while settling a
dispute.
Joseph filed for divorce from his wife and the mother of his 2
children on August 31st, 2013 at a Customary Court in Ikole
Ekiti.
He told the court that Omolara insulted his landlord when he
was trying to settle a dispute between the couple, and later
moved out of his house because she got annoyed for being
corrected.
The woman, who denied the allegation, gave her evidence on
oath to the effect that she did not insult their landlord.
She accused the plaintiff of conniving with the landlord to
sack her by giving flimsy excuses, so that he could get
another wife.
Omolara stated that she packed out of her matrimonial home
because of her husband's habit of beating her, and to escape
being killed.
She, however, consented to the divorce and prayed for the
custody of her second child who was a year and nine months
old.
The president of the court, Mrs Yemisi Ojo, dissolved the
marriage.
She upheld the prayer of the defendant on the custody of the
second child and ordered both parties to be jointly responsible
for the care, maintenance, support and education of the second
child.
She ordered that the plaintiff should single-handedly cater for
the need of the first child in his custody.
It's obvious this man is out of love for his wife.

Landlord?
