The Blast website has report that she is looking for more child support from the performer for the 4-year-old.
And she has hired lawyer Lisa Bloom and filed court papers to increase his payments.
Brown currently gets supervised visitation and pays $2,500 per month in support and another $4,000 for a nanny, who happens to be Guzman's mother.
According to the documents, Nia claims Brown has earned an average of $4,269,067 over the last two years, which can be broken down to just over $350,000 per month.
The guidelines for child support guidelines in California, which is based off income, she believes she should receive $21,000 plus per month.
She also claims with that new figure, she is owed $250,000 from Brown in retroactive child support.
However, Brown and his legal team claim her demands are too high, whils she says she his financially strapped.
Her expenses each month include; $3300 (rent), $3500 (food) and $4500 (clothes and entertainment).
Guzman says she only makes around $400 per month from an online clothing store inspired by Royalty.
The judge found in favor of the mother but couldn't order the new support amount until they have all the financial documents about Brown's income.
A decision on the new amount of child support could come next week.
