Not necessarily so Carol - as I stated, some states do not require a seal - CT being one.
Further “you will occasionally get a document which will require both your signature and your stamp and no one signs the document but yourself. This is Illegal! You CANNOT AND MUST NOT stamp any document unless it is for the purposed of acknowledging someone else’s signature.”
Again, not necessarily so - there are some acts in some states where only the notary signs the cert and the stamp is required - here in FL I’ll point to Certified Copies, VIN Verification, and Safe Deposit Box Inventory You may be referring to that company who wants us to sign and stamp the ID form without the signature…and yes, I’d agree with you on that point.
It is all very state-specific and can vary widely from state to state… MO, where the OP is from, has specific wording in their regulations - they MUST use a seal OR embosser.
