If Background Check Is Negative After Candidate Joins Should His Payment Be Withheld?

If background check is negative after candidate joins should his payment be withheld?
I have two questions
a)  If Employee who has joined just 1 week back and his background check has come negative (eg. Previous company where he has worked doesn’t exist) we terminate the employment immediately but should he be paid for the days he worked?
b)  Ideally when the employment verification process should start? After the employee joins or before joining?
Help will be appreciated

hello ,
a) He/ she cheated you , so in this case you don't have to pay anything as the duration is only 1 week.
b)Before the joining date .
Hope it will help you.

Hi
Payment can be witheld, but state the appropriate reason, addressing your second question, the verification must be done after the interview are done, but before joining the company.

A) pay for the days worked. the payment is for performing work, you may terminate the employment. but you cannot take free work. the amount may work out to be very small compared to the company's goodwill. The employee is bad, not the organization. Extrapolating the same argument as yours, if the verification process had taken longer , say some months , then what ?

Verification process should ideally being as soon as candidate conveys his acceptance and wants to join.
He should be paid for the limited period he/she worked.
