It looks like the Kardashian clan isn't all that welcoming to their soon-to-be in-law, Blac Chyna, after all.

According to TMZ, the famous sisters are purposefully trying to block Chyna from making bank using the family name.

TMZ obtained docs which show that Kim, Khloé and Kourtney's companies are shutting down Chyna's request to trademark her soon-to-be legal name after marriage, "Angela Renee Kardashian." The model was allegedly trying to get that situated for use professionally in entertainment and social media.

According to the docs, the three sisters say that if Chyna gets her way, they will "suffer damage including irreparable injury to their reputation and goodwill."

Showing that they're not on the Chyna train, they also said in the docs that Rob's fiancé is "deliberately seeking to profit from the goodwill and populatiry" of their family name.
