Referring clients to parties offering "bridging finance"

I am an Attorney specialising in conveyancing.

As part of the process, certain debts need to be paid by sellers before transfer is taken and the money is paid for them.

Hence there is a service by third parties called bridging finance. They essentially give a seller a loan against the impending purchase price coming in. This service is probably a riba based model.

I only refer non-Muslim clients to them. For that referral, the third party offers me a referral fee. Is that referral fee halaal for me ?
