It is not uncommon for an employee to be offered a severance package that provides payments that come out of the regular payroll program. In that case, the employee continues to receive a paycheck at the normal interval along with other benefits, such as health care insurance and help finding another job. However, some employers will offer a lump-sum severance payment in order to make a clean break with the employee.
Settlement payments are normally given in a lump sum. If you and your attorney agreed that the attorney would be paid on a contingency, you will be required to share that settlement payment with your attorney. That is accomplished by either having separate checks for the attorney and the employee, or having one check where each person must cosign the check.
