How does the UK(specifically NI) treat outstanding loans during a divorce?

My sister is trying to find a solution for a loan that is solely under her name for a business her ex-husband runs.

In the US (we’re Americans) some states have community property and things like this can be figured out through the courts. What options does she have in removing herself or closing this loan if the ex-husband doesn’t qualify for a loan on his own? TYIA!
I need to know how the UK handles outstanding loans during a divorce. My sister has a loan for her ex-husband's business. How can she either remove herself from the loan or close it if her ex-husband isn't able to own it himself? I know in the US, such issues can be figured out in court through community property rules and such.
