Dear friend,
Components of a Relieving Letter
Basically, a relieving letter should contain the name of the employee, their designation, the circumstances or reasons, and the date on which the employee is relieved.
Concerns with Conditional Relieving Letters
If the relieving letter prescribes any conditions like the one mentioned in the post, it shows poor drafting as well as over-cautiousness. Logically, a resignation can be accepted subject to certain reasonable conditions like serving the notice period in full, properly handing over the charge, returning all the assets of the employer entrusted to the employee in connection with the job, and clearing all dues, etc. When the employer takes their own time to disburse the F&F settlement, how can they issue a conditional relieving letter for relieving the employee from the organization? Strictly speaking, a relieving order or letter indicates the final stroke of separation by putting a mutual end to the contract of employment.
Understanding from a Legal Perspective
However, if your prospective employer has a legal bent of mind and an understanding of the essentials of a relieving letter, I don't think they'll have any objection. Even otherwise, you have the bank records for the transactions in this regard. Perhaps, your previous employer will provide the particulars of receipt in the statement of F&F settlement. If not, insist on a separate receipt.
