Chris Brown is being accused of failing to pay child support for his daughter.

Nia Guzman, the mother of five-year-old Royalty, claims the singer has yet to pay up even after being ordered to fork over $17,743 a month back in February, according to court documents obtained by the Blast.

So Guzman now is seeking over $258,000 in back child support from the R&B singer.

She now claims that along with still owing the back pay, he also has not yet provided the 'value of housing [he] agreed to supply.'

The Loyal singer is claimed to earn $7.5 million a year in the documents.

Guzman also says the lack of payment has created a 'great hardship' because she does not work and relies on him for financial support.

And Guzman claims that the 30-year-old 'has repeatedly engaged in conduct that dramatically increased the cost of litigation.

'He has ignored deposition notices, offered to participate in mediation in a court hearing then failed to even respond to potential mediation dates when proposed, and ignored settlement offers altogether,' the court docs explained.

The pair welcomed their daughter in 2015, though Chris was not made aware of her paternity until the following year. Their originally child support arrangement had him paying $2,500 monthly.

Chris and Nia have been locked in a battle over the monthly fee and last year Guzman initially requested $21,000 a month and $250k in back payment.

They were originally said to have settled on an undisclosed amount with Chris agreeing to buy Guzman a house.

Insiders told TMZ last fall that Chris and Nia, who have a famously turbulent relationship, are now on more amicable terms and getting on better than ever.

In September, the Beautiful People singer argued their daughter would be 'spoilt' if he increased his payments in line with Nia's request or gave her the $250,000 in retroactive child support she had also asked for.

He argued in court documents: 'Providing a four year old with everything she demands could be harmful and is not in her best interest.'

Nia has also claimed that Chris only has Royalty 20 percent of the time, but the chart-topper insisted he has her for at least 12 days a month.
