The mother is not a payee of the check. Assuming the check is not a cashiers check, teller's check, or certified check, you can absolutely place a case-by-case hold on it and if you have sufficient cause, you can place an exception hold.
If the check is a cashiers check, tellers check, or certified check, you can still place a case-by-case hold on it, because it is not deposited into an account of the payee. You can also place an exception hold on the item based on applicable cause.
