What is the ruling for Khul' involving a female Mukatabah (a slave contracted for her freedom)?

Primary text

The ruling concerning a Mukatabah is the same as that concerning an ordinary female slave (Qinn). This is because she does not possess the capacity to dispose of what is in her hands through gratuitous transactions. Furthermore, providing compensation in Khul' yields no benefit in terms of obtaining assets but results in detriment due to the forfeiture of her maintenance (Nafaqah) and part of her dower if the marriage was unconsummated.
