Please carefully go through your Terms of employment in your Appointment letter and Company Policy related to Employee Exit.
I assume that you are in a probation period in your current organisation .Generally in most organisations , the Notice Period during probation period is less than a month and only after you get confirmed the probation period is one month.This is for junior and middle level.But at senior level, the notice period during probation is one month.
Firstly,you will have to send your resignation through automated tool.You can check on the notice period during probation and accordingly discuss with your current employer. Also simulatenously you can start your handover so that they can relieve you at the earliest.
if they insist on one month you can ask them to deduct notice pay.
But by misleading your new employer on your employment status you have created a problem for you.
Your current employer will issue you a relieving letter / work experience certifcate mentioning the date on which you will be relieved. Also if your new employer undertakes past employment verification , they will come to know the truth.
Please avoid such things in future.
