Your tenant doesn't need permission to use Split Pay — they sign up on their own. But for them to pay you through Split Pay, you do need to do two things:
Accept the payment request they send you, within 5 business days
Create a Split Pay landlord account and connect your bank
Creating your account and connecting your bank takes about two minutes, and you only do it once. You accept once per rent plan — after that, every scheduled payment on that plan is sent to your bank account automatically. If your tenant starts a new plan, you'll get a new request to accept. No invoicing, no chasing, no fees on your end.
So technically your tenant can sign up for Split Pay any time, but they can't actually pay you with it until you've accepted and connected your bank.

Worth knowing: Split Pay also works for mortgages, car payments and student loans. If you've got any of these, same idea: split the payment, and your lender receives the full amount.
