I'd never lend money to a large organisation in my own name*, anyway. "You're trying to disfellowship me for taking a brother to court, Elder Smith? I'm not suing anyone. The plaintiff is NotFormer* LLC/LTD/PTY. LTD." (Whatever applies in which country)
The same would apply to financial deals and contracts within a congregation. Those would be between companies, not individuals.
*Apart from my personal bank accounts; I'm kind of stuck with that. 🙄
**Just my usual disclaimer: I never was a JW. I'm just using my screen name for the example.
