So long as your partners debts are not in your name then it should not have any implications for you at all from a technical point of view.
Even when couples live together in the same house and one person goes bankrupt then this will not affect the other persons financial status.
Often people worry that their credit rating will be effected but this is simply not the case if there is no financial connection between the individuals concerned.
It is also possible to submit a letter of Financial Disassociation to the credit reference agencies if a person is particulary concerned about this issue.
