Last week, after a long drawn out court battle, Usher was granted primary custody over Usher Raymond V, 4, and Naviyd Ely Raymond, 3, reported TMZ online.
Tameka believes that the ruling was biased given that the law firm that provided Usher's representative lawyer, has ties with the ruling judge.
Following the ruling, Tameka vowed to appeal against the decision and now she is ready to follow through with her promise.
Tameka said that Usher was represented by a solicitor, who was personally responsible for nearly half of the contributions to the judge's re-election campaign in 2008.
She also claimed that the lawyer served on the judge's re-election campaign committee.
During the initial ruling, Tameka pointed out that there was no evidence presented in court that showed that she wasn't fit to take care of her two kids.
She also said that she presented clear evidence of Usher's "past, current, and future inability" to care for the two children.
As of now, the judge has not ruled on her motion to appeal against the decision.
