Client refusing to sign timesheets after taking receipt of work at close of contract

[TheFaQQer]

Query: Do signed timesheets imply acceptance of the work, or are they simply a record of being on site?

It depends on the wording on the timesheet. Mine say something like "I confirm that this timesheet represents a true reflection of the time worked, I am satisfied with the work completed and authorise XYZ Agency to invoice at the agreed rate" (or similar).

Most timesheets I've seen from agencies say something similar - the client signs them and indicates that they can then be charged for your work.
